Calls from a {@literal @}{@code FastNative} method implementation to JNI functions\n * that access the managed heap or call managed code also have faster internal transitions.\n *\n *

\n * While executing a {@literal @}{@code FastNative} method, the garbage collection cannot\n * suspend the thread for essential work and may become blocked. Use with caution. Do not use\n * this annotation for long-running methods, including usually-fast, but generally unbounded,\n * methods. In particular, the code should not perform significant I/O operations or acquire\n * native locks that can be held for a long time. (Some logging or native allocations, which\n * internally acquire native locks for a short time, are generally OK. However, as the cost\n * of several such operations adds up, the {@literal @}{@code FastNative} performance gain\n * can become insignificant and overshadowed by potential GC delays.)\n * Acquiring managed locks is OK as it internally allows thread suspension.\n *

\n *\n *

\n * For performance critical methods that need this annotation, it is strongly recommended\n * to explicitly register the method(s) with JNI {@code RegisterNatives} instead of relying\n * on the built-in dynamic JNI linking.\n *

\n *\n *

\n * The {@literal @}{@code FastNative} optimization was implemented for system use since\n * Android 8 and became CTS-tested public API in Android 14. Developers aiming for maximum\n * compatibility should avoid calling {@literal @}{@code FastNative} methods on Android 13-.\n * The optimization is likely to work also on Android 8-13 devices (after all, it was used\n * in the system, albeit without the strong CTS guarantees), especially those that use\n * unmodified versions of ART, such as Android 12+ devices with the official ART Module.\n * The built-in dynamic JNI linking is working only in Android 12+, the explicit registration\n * with JNI {@code RegisterNatives} is strictly required for running on Android versions 8-11.\n * The annotation is ignored on Android 7-.\n *

\n *\n *

\n * Deadlock Warning: As a rule of thumb, any native locks acquired in a\n * {@literal @}{@link FastNative} call (despite the above warning that this is an unbounded\n * operation that can block GC for a long time) must be released before returning to managed code.\n *

\n *\n *

\n * Say some code does:\n *\n * \n * fast_jni_call_to_grab_a_lock();\n * does_some_java_work();\n * fast_jni_call_to_release_a_lock();\n * \n *\n *

\n * This code can lead to deadlocks. Say thread 1 just finishes\n * {@code fast_jni_call_to_grab_a_lock()} and is in {@code does_some_java_work()}.\n * GC kicks in and suspends thread 1. Thread 2 now is in {@code fast_jni_call_to_grab_a_lock()}\n * but is blocked on grabbing the native lock since it's held by thread 1.\n * Now thread suspension can't finish since thread 2 can't be suspended since it's doing\n * FastNative JNI.\n *

\n *\n *

\n * Normal JNI doesn't have the issue since once it's in native code,\n * it is considered suspended from java's point of view.\n * FastNative JNI however doesn't do the state transition done by JNI.\n *

\n *\n *

\n * Note that even in FastNative methods you are allowed to\n * allocate objects and make upcalls into Java code. A call from Java to\n * a FastNative function and back to Java is equivalent to a call from one Java\n * method to another. What's forbidden in a FastNative method is blocking\n * the calling thread in some non-Java code and thereby preventing the thread\n * from responding to requests from the garbage collector to enter the suspended\n * state.\n *

\n *\n *

\n * Has no effect when used with non-native methods.\n *

\n * 1、ContentProvider天生支持多进程访问；
\n * 2、使用内部私有BroadcastReceiver实现多进程OnSharedPreferenceChangeListener监听；
\n * \n * 使用方法：AndroidManifest.xml中添加provider申明：
\n * 
\n * <provider android:name=\"com.tencent.mm.sdk.patformtools.MultiProcessSharedPreferences\"\n * android:authorities=\"com.tencent.mm.sdk.patformtools.MultiProcessSharedPreferences\"\n * android:exported=\"false\" />\n * <!-- authorities属性里面最好使用包名做前缀，apk在安装时authorities同名的provider需要校验签名，否则无法安装；--!/>
\n *
\n * \n * ContentProvider方式实现要注意：
\n * 1、当ContentProvider所在进程android.os.Process.killProcess(pid)时，会导致整个应用程序完全意外退出或者ContentProvider所在进程重启；
\n * 重启报错信息：Acquiring provider for user 0: existing object's process dead；
\n * 2、如果设备处在“安全模式”下，只有系统自带的ContentProvider才能被正常解析使用，因此put值时默认返回false，get值时默认返回null；
\n * \n * 其他方式实现SharedPreferences的问题：
\n * 使用FileLock和FileObserver也可以实现多进程SharedPreferences读写，但是会有兼容性问题：
\n * 1、某些设备上卸载程序时锁文件无法删除导致卸载残留，进而导致无法重新安装该程序（报INSTALL_FAILED_UID_CHANGED错误）；
\n * 2、某些设备上FileLock会导致僵尸进程出现进而导致耗电；
\n * 3、僵尸进程出现后，正常进程的FileLock会一直阻塞等待僵尸进程中的FileLock释放，导致进程一直阻塞；

It also adds the `MMKVConfig` all-in-one configuration and several bug fixes.\n\n### Changes for All Platforms\n* **Feature:** Refactored the callback system into a **unified `MMKVHandler`** interface. All callbacks (log redirecting, error handling, content change notification, content loaded notification) are now grouped in a single handler registered via `registerHandler()`. The old per-callback `registerLogHandler()` / `registerErrorHandler()` / `registerContentChangeHandler()` / `registerContentLoadedHandler()` APIs have been removed.\n* **Feature:** Added `onMMKVContentLoadSuccessfully` callback, triggered when an MMKV file is loaded/mapped successfully.\n* **Feature:** Added `MMKVConfig` for all-in-one instance configuration, supporting all options (`mode`, `cryptKey`, `aes256`, `expectedCapacity`, `enableKeyExpire`, `expiredInSeconds`, `enableCompareBeforeSet`, `recover`, `itemSizeLimit`) in a single struct/class.\n* **Feature:** Added `defaultMMKV(config)` variant for creating the default instance with full configuration.\n* **Fix:** Robust check on encryption mode ([#1642](https://github.com/nicksunday/mmkv/issues/1642)).\n* **Fix:** Protect from `delete` file failure on corrupted files.\n* **Fix:** Protect from `m_file` not valid for `isDiskOfMMAPFileCorrupted()`.\n* **Fix:** Reduce `absolutePath()` calls as much as possible.\n* Drop old-style actual size downgrade support.\n* MMKV must be compiled with **C++17**.\n\n### Android\n* **Change:** Merged `MMKVContentChangeNotification` into `MMKVHandler`. The old `MMKVContentChangeNotification` interface is now `@Deprecated`.\n* **Fix:** Fix `fcntl()` OFD lock failure on ashmem ([#1637](https://github.com/nicksunday/mmkv/issues/1637)).\n* Merge ashmem size with `expectedCapacity`.\n* Correctly collect so-symbols.\n\n### iOS/macOS\n* **Feature:** Added `getBytes()` with `string_view` key for ObjC++.\n* **Fix:** Fixed a memory leak on getting `NameSpace` instance.\n* Support **Swift Package Manager** ([#535](https://github.com/nicksunday/mmkv/issues/535)).\n* Fix compile error on `tryAtomicRename()`.\n\n### HarmonyOS NEXT\n* Merge ashmem size with `expectedCapacity`.\n\n### Flutter\n* Updated to use the unified `MMKVHandler` callback interface.\n\n### Win32\n* Fix: Convert log message to UTF-8 for Win32 client.\n* Verify all pages for corrupted file detection.\n\n## v2.3.0 / 2025-12-03 (Breaking Change)\n\nThis release is a **breaking change** and introduces **AES-256 encryption** for enhanced security.\n\n### All Platforms\n\n* **Feature:** Added **AES-256 encryption** functionality. To upgrade an existing encrypted MMKV instance to AES-256, first load it using the old key. Then, call the `reKey()` method with the new key and set the `aes256` parameter to `true`, e.g., `reKey(newKey, aes256=true)`. After this, you should use the new key for all future loads of this instance.\n* **Fix:** Resolved a crash that occurred when loading an empty file in `ReadOnly` mode.\n* **Fix:** Added protection against the `weakly_canonical()` exception caused by an invalid file path.\n* **Fix:** Fixed an issue where the file size could change during multi-process loading.\n* **Fix:** Corrected a bug where a single key could be overridden incorrectly when upgrading from a v1.1.x version.\n\n### iOS/macOS/watchOS\n\n* **Change:** Dropped support for the **armv7k** architecture on Apple Watch. To adapt, you should add `armv7k` to the **\"Excluded Architectures\"** setting for your Apple Watch App or Extension target.\n* **Important:** Do not upgrade to this version if you need to maintain `armv7k` support.\n* **Change:** Dropped deprecated methods that use the `relativePath:` parameter. If you were using these methods, please migrate to those using the `rootPath:` parameter instead.\n\n### POSIX\n\n* **Change:** Dropped support for **armv7** architecture. **Do not** upgrade to this version if you need to maintain `armv7` support.\n\n## v2.2.4 / 2025-09-25\nThis is a hotfix release mainly for iOS/macOS CocoaPods users.\n\n### Changes for All platforms\n* Improve the performance of MMBuffer a little bit in some cases.\n\n### iOS/macOS\n* Make MMKV and MMKVCore podspec define modules.\n\n## v2.2.3 / 2025-08-20\nThis is a feature release that brings **full desktop support to Flutter**. It also includes key bug fixes and enhancements for Android and other platforms.\n\n### Flutter\n* **Added Full Desktop Support**: MMKV for Flutter now officially supports **Windows**, **macOS**, and **Linux**.\n* **Example App**: The example application has been updated to run on all new desktop platforms.\n\n### Android\n* **Feature**: Added `MMKVHandler.getNativeLogHandler()` to allow native handling of MMKV logs from C++ code, improving performance.\n* **Fix**: Corrected an integer overflow bug where a native memory address exceeding `Long.MAX_VALUE` was misinterpreted as a negative number.\n* **Fix**: Prevented potential memory overflow by ensuring JNI local references are deleted after use. \n* **Fix**: Fixed an issue where directories for special relative paths were not being created correctly.\n* **Enhancement**: Improved the thread-safety of the callback handler to prevent crashes.\n\n### iOS/macOS\n\n* **Fix**: Resolved a build error on Apple platforms that occurred when the `MMKV_APPLE` flag was not set.\n* **Fix**: Addressed a naming conflict in the Swift implementation.\n\n### Windows\n\n* **Fix**: Corrected character encoding issues in the Win32 demo by converting files to UTF-8.\n\n## v2.2.2 / 2025-05-08\nThis is a hot fix version mainly **for Android/Linux platforms**. It’s highly recommended for v2.2.0~v2.2.1 users.\n### Changes for All platforms\n* Improve file lock consistency for Mayfly FD MMKV instances.\n\n### Android\n* Fix a potential ANR on multi-process mode MMKV init/creation.\n\n### POSIX\n* Fix a potential ANR on multi-process mode MMKV init/creation on Linux.\n\n### iOS/macOS\n* Retain the callback handler to prevent a potential short-lived callback handler from crashing.\n\n### Win32\n* Improve efficiency on MMKV instance init/creation.\n\n## v2.2.1 / 2025-04-25\n### Changes for All platforms\n* Add `importFrom()`.\n\n### Android\n* Fix a bug on initialization.\n\n## v2.2.0 / 2025-04-24\nWe introduce the **Mayfly FD** (short-lived file descriptor) enhancement, reducing MMKV's fd footprint by half and more. For a single-process mode MMKV instance, the fd footprint is reduced to zero (except Android/OHOS, details below). For a multi-process mode MMKV instance, the fd footprint is reduced by half, for we still need a long-lived fd to inter-process lock the shared memory.\n### Changes for All platforms\n* Add **Mayfly FD** (short-lived file descriptor) enhancement.\n* Improve multi-process access efficiency by about 20%.\n* Add `checkExist()` to check if a MMKV instance exists on disk.\n* Drop deprecated armv7 AES hardware acceleration.\n\n### Android\n* Reduce the fd footprint by half. For a single-process mode MMKV instance, we still need a long-lived fd to support the **process-mode checker** and **legacy name upgrading**. In the far future, when all legacy names have been upgraded, we might drop the long-lived fd like other platforms.\n* Upgrade Android compileSdk/targetSdk to 35, NDK to 28.1, Java to 11, Gradle to 8.11.1, and AGP to 8.9.2.\n\n### HarmonyOS NEXT\n* Reduce the fd footprint by half. For a single-process mode MMKV instance, we still need a long-lived fd to support the **legacy name upgrading**. In the far future, when all legacy names have been upgraded, we might drop the long-lived fd like other platforms.\n* Drop `checkProcessMode()`, it’s never been used.\n* Improve obfuscation configuration with relative path.\n\n### iOS\n* Add `+mmkvGroupPath` to get the group folder for MMKV multi-process storage.\n\n### Flutter\n* Add `isFileValid()`.\n* Add `groupPath()` on iOS.\n* Fix `checkContentChangedByOuterProcess()` not working bug.\n\n## v2.1.0 / 2025-02-18\nHappy Chinese New Year! \nThis is a **breaking change version for the Android/OHOS** platform. Read the change log bellow and upgrade carefully.\n### Changes for All platforms\n* Add the `NameSpace` feature that easily supports customizing a root directory.\n* Add protection from bad disk records of MMKV files.\n* Fix FileLock not being unlocked on destruction.\n* Improve directory creation on `ReadOnly` mode.\n\n### Android\n* **Breaking change**: Migrate legacy MMKV in a custom directory to normal MMKV. Historically Android/OHOS mistakenly use mmapKey as mmapID, which will be problematic with the `NameSpace` feature. Starting from v2.1.0, MMKV will try to migrate them back to normal when possible. \nIt's highly recommended that you **upgrade to v2.0.2/v1.3.11 first** with **forward support** of normal MMKV in a custom directory.\n* Supports using MMKV directly in C++ code.\n* Improve inter-process locking by using `F_OFD_SETLK` instead of `F_SETLK`.\n* Add *experimental* protection from bad disk records of MMKV files.\n\n### HarmonyOS NEXT\n* **Breaking change**: Migrate legacy MMKV in a custom directory to normal MMKV. Historically Android/OHOS mistakenly use mmapKey as mmapID, which will be problematic with the `NameSpace` feature. Starting from v2.1.0, MMKV will try to migrate them back to normal when possible. \nIt's highly recommended that you **upgrade to v2.0.2/v1.3.11 first** with **forward support** of normal MMKV in a custom directory.\n* Supports using MMKV directly in C++ code.\n* Improve inter-process locking by using `F_OFD_SETLK` instead of `F_SETLK`.\n* Add *experimental* protection from bad disk records of MMKV files.\n\n### iOS/macOS\n* Upgrade to iOS 13, macOS 10.15, and watchOS 6 to support the `NameSpace` functionality.\n* Supports using MMKV directly in C++ code.\n* Drop the background `mlock()` protection given that we are iOS 13+.\n* Add *tested* protection from bad disk records of MMKV files.\n* Fix a package error when using MMKV by submodule.\n\n### Flutter\n* Remove unused imports and fix deprecated implementations. \n* Support flutter 3.29.\n\n### Win32\n* Add *tested* protection from bad disk records of MMKV files.\n\n### POSIX\n* Improve inter-process locking by using `F_OFD_SETLK` instead of `F_SETLK`.\n* Add *experimental* protection from bad disk records of MMKV files.\n* Fix a compile error on the GNU toolchain.\n\n### Golang\n* Fix a link error in the armv8 arch.\n* Improve multi-platform building.\n\n## v2.0.2 / 2024-12-27\nMary holiday and a happy new year!\n### Changes for All platforms\n* Fix a bug that MMKV might fail to backup/restore across different filesystems.\n* Add protection from invalid value size of auto-key-expire mmkv.\n\n### Android\n* If the running App is 32-bit only, warn about it (by throwing `UnsupportedArchitectureException`) before trying to load native lib.\n* Add forward support for the correct filename with a custom root path.\n\n### HarmonyOS NEXT\n* Obfuscation fully supported.\n* Use atomic file rename on OHOS.\n* Add forward support for the correct filename with a custom root path.\n\n### Win32\n* Only `mmap()` on `ftruncate()`/`zeroFillFile()` failure iff we have a valid file mapping before.\n\n## v2.0.1 / 2024-11-12\n**This is a hotfix release.**\n### Changes for All platforms\n* Fix a bug that might cause MMKV to become dead-locked for other threads after decoding container-type values. The affected platforms and value types are listed below. So don't be surprised if you find no update on the unaffected platforms.\n\n### HarmonyOS NEXT\n* Fix a bug that MMKV might become dead-locked for other threads after `decodeStringSet()` / `decodeNumberSet` / `decodeBoolSet` or decoding `TypedArray`.\n\n### Flutter\n* Fix the bug on HarmonyOS NEXT listed above. A version named v2.0.1 was added to fix the Android version conflict between the LTS series & v2.0. Thanks to the federated plugins framework, only the underlying `mmkv_ohos` plugin is upgraded, the `mmkv` plugin stays the same.\n\n### POSIX\n* Fix a bug that MMKV might become dead-locked for other threads after decoding `std::vector` or `std::span` values.\n\n## v2.0.0 / 2024-10-21\n**This release is a breaking change release, especially for Android.**\n### Changes for All platforms\n* Add **readonly mode** support.\n* Fix a compile error when `MMKV_DISABLE_CRYPT` is defined and MMKV is built by source in DEBUG.\n\n### Android\n* Support 16K page size for Android 15.\n* Drop the support of **32-bit ABI**.\n* Bump the mini **SDK level to API 23**.\n\n### iOS / macOS\n* Add Mac Catalyst support\n\n### Flutter\n* Add add log/error/content-change callback.\n\n### HarmonyOS NEXT\n* Add add log/error/content-change callback.\n* Support obfuscation. For the time being, you will have to manually copy the content of MMKV's [consumer-rules.txt](https://github.com/Tencent/MMKV/blob/master/OpenHarmony/MMKV/consumer-rules.txt) into your App's obfuscation-rules.txt.\n\n### Win32\n* Replace `random()` with `rand()` to fix a compile error.\n\n## v1.3.9 / 2024-07-26\n**This is a Long Term Support (LTS) release.**\n### Changes for All platforms\n* Fix a data corruption bug on an encrypted MMKV with only one key value stored.\n* Make encryption more resilient from brute force cracking.\n* Fix a bug that `pthread_mutex` is not being destroyed correctly.\n\n### Android\n* Use an alternative way to get the process name to avoid potential App review issues.\n* Upgrade to NDK 26.3.11579264.\n\n### Flutter\n* Add support for HarmonyOS NEXT. In fact, a temp version named v1.3.8 adds this support with the native lib of v1.3.7. To avoid potential confusion, bump both versions to v1.3.9.\n\n## v1.3.7 / 2024-07-08\n### Android & Flutter\n**This Long Term Support (LTS) release** primarily reintroduces support for the ARMv7 architecture and lowers the minimum SDK version requirement to 21. Please note that only critical bug fixes will be applied to the 1.3.x series. New features will be introduced in version 2.0 and later, which will discontinue support for 32-bit architectures and raise the minimum SDK version requirement to 23.\n\n### For other platforms\nThis is exactly the same as v1.3.6, so don't be surprised if you don't see this version in CocoaPods or OHPM.\n\n## v1.3.6 / 2024-07-05\n### Changes for All platforms\n* The Core library now upgrades the C++ standard from C++17 to C++20 to make the most of morden C++ feature such as `Concept` & unordered containers with `std::string_view` as key. From now on, if you build MMKV by source (iOS, Windows, POSIX, etc), you will need a C++ compiler that supports the C++20 standard. If you only use MMKV in binary (Android, OHOS, etc), this upgrade of the C++ compiler is not required.\n* The key type changes from `std::string` to `std::string_view`, to avoid unnecessary string construction and destruction when the key is a raw string.\n\n### Android\n* Use the latest ashmem API if possible.\n* Use the latest API to get the device API level.\n\n### Flutter\n* MMKV will try to load libmmkv.so before Dart code, to reduce the error of loading library in Android.\n\n### HarmonyOS NEXT\n* Fix a bug that a `String` value might get truncated on encoding.\n* MMKV returns `undefined` when a key does not exist, previously a default value of the type (`false` for `boolean`, `0` for `number`, etc) is returned.\n* Add the feature to encode/decode a `float` value.\n* Add the feature to encode/decode a `TypedArray` value.\n* Support encoding a part of an `ArrayBuffer`.\n\n### iOS/macOS\n* Hide the default `NSObject.initialize()` from Swift/ObjC to prevent potential misuse.\n\n### POSIX\n* Support encode/decode `std::vector` or `std::span` values, with T as primitive types.\n* Fix a compile error on Linux env.\n* Fix a compile error on the GNU compiler.\n* Fix a compile error with some old version of zlib (on CentOS).\n\n### Python\n* Python now runs on Windows. Check out the latest [wiki](https://github.com/Tencent/MMKV/wiki/python_setup) for instructions.\n\n### Windows\n* Support encode/decode `std::vector` or `std::span` values, with T as primitive types.\n* Python now runs on Windows. Check out the latest [wiki](https://github.com/Tencent/MMKV/wiki/python_setup) for instructions.\n\n## v1.3.5 / 2024-04-24\n### HarmonyOS NEXT\n* This is the first official support of HarmonyOS NEXT.\n* Most things actually work!\n* Checkout the [wiki](https://github.com/Tencent/MMKV/wiki/ohos_setup) for more.\n\n### Flutter\n* Migrate to federated plugins to avoid the iOS rename headache. From now on, no more renaming from `mmkv` to `mmkvflutter` is needed.\n* Bump iOS Deployment Target to iOS 12.\n* Bump Android minSdkVersion to 23.\n\n### iOS & macOS\n* Avoid using so-called privacy APIs (`lstat()`, `fstat()`, `NSUserDefaults`).\n* Bump iOS Deployment Target to iOS 12.\n\n### Android\n* Bump minSdkVersion to 23.\n* Drop armv7 & x86 support.\n\n### POSIX\n* Use the embedded libz when libz can not be found.\n* Fix compile error when building with gcc.\n\n### Windows\n* Support x64 architecture.\n\n## v1.3.4 / 2024-03-15\n### Changes for All platforms\n* Make `trim()` more robust in multi-process mode.\n\n### iOS & macOS\n* Support visionOS.\n\n### POSIX\n* Fix a compile error on `::unlink()`.\n\n## v1.3.3 / 2024-01-25\n### Changes for All platforms\n* Add `removeStorage()` static method to safely delete underlying files of an MMKV instance.\n* Add protection from a potential crash of a multi-process MMKV loading due to the MMKV file not being valid.\n* Add back the lazy load feature. It was first introduced in v1.2.16. But it was rollbacked in v1.3.0 of potential ANR & file corruption. Now it's clear that the bug was caused by something else, it's time to bring it back.\n* **Optimize loading speed** by using shared inter-process lock unless there's a need to truncate the file size, which is rare.\n* Make these two lately added features **more robust**: customizing the initial file size & optimizing write speed when there's only one key inside MMKV.\n\n### Android\n* Fix a bug that `null` is returned when the value is in fact an empty ByteArray.\n* Fix AGP >= 8 package namespace error.\n* Fix the `FastNative` naming conflict.\n* Upgrade to SDK 34.\n* Upgrade `androidx.annotation` to v1.7.1.\n\n### iOS & macOS\n* On the Xcode 15 build, an App will crash on iOS 14 and below. Previously we have recommended some workarounds (check the v1.3.2 release note for details). Now you can use Xcode 15.1 to fix this issue.\n* Fix a bug that the multi-process mode won't configure correctly. It was introduced in v1.3.2.\n* Fix a macro naming conflict.\n* Avoid using a so-called privacy API when creating temp files.\n\n### POSIX\n* Fix a compile error on `memcpy()`.\n\n### Golang\n* Fix a compile error when `MMKV_DISABLE_CRYPT` is on.\n\n## v1.3.2 / 2023-11-20\nAmong most of the features added in this version, the credit goes to @kaitian521.\n### Changes for All platforms\n* Add the feature of customizing the **initial file size** of an MMKV instance.\n* **Optimize write speed** when there's only one key inside MMKV, the new key is the same as the old one, and MMKV is in `SINGLE_PROCESS_MODE`.\n* **Optimize write speed** by overriding from the beginning of the file instead of append in the back, when there's zero key inside MMKV, and MMKV is in `SINGLE_PROCESS_MODE`.\n* Add the feature of `clearAll()` with keeping file disk space unchanged, **reducing the need to expand file size** on later insert & update operations. This feature is off by default, you will have to call it with relative params or newly added methods. \n* Add the feature of **comparing values before setting/encoding** on the same key.\n* Fix a potential bug that the MMKV file will be invalid state after a successful expansion but a failure `zeroFill()`, will lead to a crash.\n* Fix a potential crash due to other module/static lib turn-off **RTTI**, which will cause MMKV to fail to catch `std::exception`.\n* Fix several potential crash due to the MMKV file not being valid.\n\n### Android\n* Use the `-O2` optimization level by default, which will **reduce native lib size** and improve read/write speed a little bit.\n* Experimantal use `@fastNative` annotation on `enableCompareBeforeCompare()` to speed up JNI call.\n\n### iOS & macOS\n* Optimize auto-clean logic to **reduce lock waiting time**.\n* Turn-off mlock() protection in background on iOS 13+. We have **verified it on WeChat** that the protection is no longer needed from at least iOS 13. Maybe iOS 12 or older is also not needed, but we don't have the chance to verify that because WeChat no longer supports iOS 12.\n\n#### Known Issue\n* On Xcode 15 build, App will crash on iOS 14 and below. The bug is introduced by Apple's new linker. The official solutions provided by Apple are either:\n * Drop the support of iOS 14.\n * Add `-Wl,-weak_reference_mismatches,weak` or `-Wl,-ld_classic` options to the `OTHER_LDFLAGS` build setting of Xcode 15. Note that these options are **not recognized** by older versions of Xcode.\n * Use older versions of Xcode, or **wait for Xcode 15.2**.\n\n## v1.3.1 / 2023-8-11\nThis is a hotfix version. It's **highly recommended** that v1.2.16 & v1.3.0 users upgrade as soon as possible.\n\n### Changes for All platforms\n* Fix a critical bug that might cause multi-process MMKV corrupt. This bug was introduced in v1.2.16.\n* Add the ability to filter expired keys on `count()` & `allKeys()` methods when auto key expiration is turn on.\n* Reduce the `msync()` call on newly created MMKV instances.\n\n### iOS & macOS\n* Fix a bug that NSKeyedArchive object might fail to decode when auto key expiration is turn on.\n\n## v1.3.0 / 2023-06-14\n### Changes for All platforms\n* Add auto key expiration feature. Note that this is a breaking change, once upgrade to auto expiration, the MMKV file is not valid for older versions of MMKV (v1.2.16 and below) to correctly operate.\n* Roll back the lazy load optimization due to reported ANR issues. It was introduced in v1.2.16.\n\n### iOS & macOS\n* Fix a potential memory leak on setting a new value for an existing key.\n* Upgrade min support target to iOS 11 / macOS 10.13 / tvOS 13 / watchOS 4.\n\n### Windows\n* Fix a bug that might fail to truncate the file size to a smaller size in some cases.\n\n### Flutter\n* The version of MMKV for Flutter is now the same as the MMKV native library.\n* Starting from v1.3.0, Flutter for Android will use `com.tencent:mmkv`. Previously it's `com.tencent:mmkv-static`. It's the same as `com.tencent:mmkv` starting from v1.2.11.\n\n## v1.2.16 / 2023-04-20\n### Changes for All platforms\n* Optimization: The actual file content is lazy loaded now, saving time on MMKV instance creation, and avoiding lock waiting when a lot of instances are created at the same time.\n* Fix a bug when restoring a loaded MMKV instance the meta file might mistakenly report corrupted.\n\n### Android\n* Optimization: Remove unnecessary binder call on main process instantiation.\n\n### Flutter\n* Fix a crash on decoding an empty list.\n* Remove deprecated dependence.\n* Make the script more robust to fix the iOS Flutter plugin name.\n\n### Windows\n* Fix a string format bug on the MinGW64 environment.\n\n### golang\n* Fix a build error on 32-bit OS.\n\n## v1.2.15 / 2023-01-12\n### Changes for All platforms\n* Log handler now handles all logs from the very beginning, especially the logs in initialization.\n* Log handler register method is now deprecated. It's integrated with `initialize()`.\n* Fix a bug that `lock()`/`unlock()`/`try_lock()` is not thread-safe.\n\n### Flutter\n* Reduce the privacy info needed to obtain android `sdkInt`, avoid unnecessary risk on Android App Review.\n\n### iOS & macOS\n* Fix a compile error on macOS.\n* Fix a bug that some ObjC exceptions are not being caught.\n* Add assert on nil MMKV base path, protect from mis-using MMKV in global variable initialization.\n* Starting from v1.2.15, one must call `+[MMKV initializeMMKV:]` manually before calling any MMKV methods.\n\n### golang\n* Fix a compile error on GCC.\n\n### Windows\n* Support CMake project on Windows.\n\n## v1.2.14 / 2022-08-10\n### Changes for All platforms\n* Fix a bug that `MMKV.getXXX()` may return invalid results in multi-process mode.\n\n### Android\n* Return `[]` instead of `null` on empty `StringSet` from `MMKV.decodeStringSet()` methods.\n* Upgrade Android Compile & Target SDK to `32`.\n\n### iOS\n* Protect from the crash in `-[MMKV getObject:forKey:]` method when the key-value doesn't exist.\n\n## v1.2.13 / 2022-03-30\n\n### Android\n* Fix crash on using Ashmem while `MMKV_DISABLE_CRYPT` macro is defined.\n\n### iOS\n* Add ability to retrieve key existece while getting value, aka `-[MMKV getXXX:forKey:hasValue:]` methods.\n\n### POSIX\n* Add ability to retrieve key existece while getting value, aka `MMKV::getXXX(key, defaultValue, hasValue)` methods.\n\n### Windows\n* Add ability to retrieve key existece while getting value, aka `MMKV::getXXX(key, defaultValue, hasValue)` methods.\n\n## v1.2.12 / 2022-01-17\n### Changes for All platforms\n* Fix a bug that a subsequential `clearAll()` call may fail to take effect in multi-process mode.\n* Hide some OpenSSL symbols to prevent link-time symbol conflict, when an App somehow also static linking OpenSSL.\n\n### Android\n* Upgrade `compileSdkVersion` & `targetSdkVersion` from `30` to `31`.\n\n## v1.2.11 / 2021-10-26\n\n### Android\n* Due to increasing report about crash inside STL, we have decided to make MMKV **static linking** `libc++` **by default**. Starting from v1.2.11, `com.tencent:mmkv-static` is the same as `com.tencent:mmkv`.\n* For those still in need of MMKV with shared linking of `libc++_shared`, you could use `com.tencent:mmkv-shared` instead.\n* Add backup & restore ability.\n\n### iOS / macOS\n* Add backup & restore ability.\n* Support tvOS.\n* Fix a compile error on some old Xcode.\n\n### Flutter (v1.2.12)\n* Add backup & restore ability.\n\n### POSIX / golang / Python\n* Add backup & restore ability.\n* Fix a compile error on Gentoo.\n\n### Windows\n* Add backup & restore ability.\n\n## v1.2.10 / 2021-06-25\nThis version is mainly for Android & Flutter. \n\n### Android\n* Complete **JavaDoc documentation** for all public methods, classes, and interfaces. From now on, you can find the [API reference online](https://javadoc.io/doc/com.tencent/mmkv).\n* Drop the support of **armeabi** arch. Due to some local build cache mistake, the last version (v1.2.9) of MMKV still has an unstripped armeabi arch inside. This is fixed.\n* Change `MMKV.mmkvWithID()` from returning `null` to throwing exceptions on any error.\n* Add `MMKV.actualSize()` to get the actual used size of the file.\n* Mark `MMKV.commit()` & `MMKV.apply()` as deprecated, to avoid some misuse after migration from SharedPreferences to MMKV.\n\n### Flutter (v1.2.11)\n* Bug Fixed: When building on iOS, occasionally it will fail on symbol conflict with other libs. We have renamed all public native methods to avoid potential conflict.\n* Keep up with MMKV native lib v1.2.10.\n\n## v1.2.9 / 2021-05-26\nThis version is mainly for Android & Flutter. \n\n### Android\n* Drop the support of **armeabi** arch. As has been mention in the last release, to avoid some crashes on the old NDK (r16b), and make the most of a more stable `libc++`, we have decided to upgrade MMKV's building NDK in this release. That means we can't support **armeabi** anymore. Those who still in need of armeabi can **build from sources** by following the [instruction in the wiki](https://github.com/Tencent/MMKV/wiki/android_setup).\n\nWe really appreciate your understanding.\n\n### Flutter (v1.2.10)\n* Bug Fixed: When calling `MMKV.encodeString()` with an empty string value on Android, `MMKV.decodeString()` will return `null`.\n* Bug Fixed: After **upgrading** from Flutter 1.20+ to 2.0+, calling `MMKV.defaultMMKV()` on Android might fail to load, you can try calling `MMKV.defaultMMKV(cryptKey: '\\u{2}U')` with an **encrytion key** '\\u{2}U' instead.\n* Keep up with MMKV native lib v1.2.9.\n\n## v1.2.8 / 2021-05-06\nThis will be the last version that supports **armeabi arch** on Android. To avoid some crashes on the old NDK (r16b), and make the most of a more stable `libc++`, we have decided to upgrade MMKV's building NDK in the next release. That means we can't support **armeabi** anymore. \n\nWe really appreciate your understanding.\n\n### Android\n* Migrate MMKV to Maven Central Repository. For versions older than v1.2.7 (including), they are still available on JCenter.\n* Add `MMKV.disableProcessModeChecker()`. There are some native crash reports due to the process mode checker. You can disable it manually.\n* For the same reason described above (native crashed), MMKV will now turn off the process mode checker on a non-debuggable app (aka, a release build).\n* For MMKV to detect whether the app is debuggable or not, when calling `MMKV.initialize()` to customize the root directory, a `context` parameter is required now.\n\n### iOS / macOS\n* Min iOS support has been **upgrade to iOS 9**.\n* Support building by Xcode 12.\n\n### Flutter (v1.2.9)\n* Support null-safety.\n* Upgrade to flutter 2.0.\n* Fix a crash on the iOS when calling `encodeString()` with an empty string value.\n\n**Known Issue on Flutter** \n\n* When calling `encodeString()` with an empty string value on Android, `decodeString()` will return `null`. This bug will be fixed in the next version of Android Native Lib. iOS does not have such a bug.\n\n### Windows\n* Fix a compile error on Visual Studio 2019.\n\n## v1.2.7 / 2020-12-25\nHappy holidays everyone!\n \n### Changes for All platforms\n* Fix a bug when calling `sync()` with `false ` won't do `msync()` asynchronous and won't return immediately.\n\n### Android\n* Fix an null pointer exception when calling `putStringSet()` with `null`.\n* Complete review of all MMKV methods about Java nullable/nonnull annotation.\n* Add API for `MMKV.initialize()` with both `Context` and `LibLoader` parammeters.\n\n### Flutter (v1.2.8)\n* Fix a crash on the iOS simulator when accessing the default MMKV instance.\n* Fix a bug on iOS when initing the default MMKV instance with a crypt key, the instance is still in plaintext.\n\n### Golang\nAdd golang for POSIX platforms. Most things actually work!. Check out the [wiki](https://github.com/Tencent/MMKV/wiki/golang_setup) for information.\n\n## v1.2.6 / 2020-11-27\n### Changes for All platforms\n* Fix a file corruption when calling `reKey()` after `removeKeys()` has just been called.\n\n### Android\n* Fix compile error when `MMKV_DISABLE_CRYPT` is set.\n* Add a preprocess directive `MMKV_DISABLE_FLUTTER` to disable flutter plugin features. If you integrate MMKV by source code, and if you are pretty sure the flutter plugin is not needed, you can turn that off to save some binary size.\n\n### Flutter (v1.2.7)\nAdd MMKV support for **Flutter** on iOS & Android platform. Most things actually work! \nCheck out the [wiki](https://github.com/Tencent/MMKV/wiki/flutter_setup) for more info.\n\n## v1.2.5 / 2020-11-13\nThis is a pre-version for Flutter. The official Flutter plugin of MMKV will come out soon. Stay Tune!\n\n### iOS / macOS\n* Fix an assert error of encrypted MMKV when encoding some `` objects.\n* Fix a potential leak when decoding duplicated keys from the file.\n* Add `+[MMKV pageSize]`, `+[MMKV version]` methods.\n* Add `+[MMKV defaultMMKVWithCryptKey:]`, you can encrypt the default MMKV instance now, just like the Android users who already enjoy this for a long time.\n* Rename `-[MMKV getValueSizeForKey:]` to `-[MMKV getValueSizeForKey: actualSize:]` to align with Android interface.\n\n### Android\n* Fix a potential crash when getting MMKV instances in multi-thread at the same time.\n* Add `MMKV.version()` method.\n\n## v1.2.4 / 2020-10-21\nThis is a hotfix mainly for iOS.\n\n### iOS / macOS\n* Fix a decode error of encrypted MMKV on some devices.\n\n### Android\n* Fix a potential issue on checking `rootDir` in multi-thread while MMKV initialization is not finished.\n\n## v1.2.3 / 2020-10-16\n### Changes for All platforms\n* Fix a potential crash on 32-bit devices due to pointer alignment issue.\n* Fix a decode error of encrypted MMKV on some 32-bit devices.\n\n### iOS / macOS\n* Fix a potential `crc32()` crash on some kind of arm64 devices.\n* Fix a potential crash after calling `+[MMKV onAppTerminate]`.\n\n### Android\n* Fix a rare lock conflict on `checkProcessMode()`.\n\n### POSIX\nAdd MMKV support for **Python** on POSIX platforms. Most things actually work! \nCheck out the [wiki](https://github.com/Tencent/MMKV/wiki/python_setup) for more info.\n\n## v1.2.2 / 2020-07-30\n\n### iOS / macOS\n* Add auto clean up feature. Call `+[MMKV enableAutoCleanUp:]` to enable auto cleanup MMKV instances that not been accessed recently.\n* Fix a potential crash on devices under iPhone X.\n\n### Android\n* Add multi-process mode check. After so many issues had been created due to mistakenly using MMKV in multi-process mode in Android, this check is added. If an MMKV instance is accessed with `SINGLE_PROCESS_MODE` in multi-process, an `IllegalArgumentException` will be thrown.\n\n### POSIX\n* Add support for armv7 & arm64 arch on Linux.\n\n## v1.2.1 / 2020-07-03\nThis is a hotfix release. Anyone who has upgraded to v1.2.0 should upgrade to this version **immediately**.\n\n* Fix a potential file corruption bug when writing a file that was created in versions older than v1.2.0. This bug was introduced in v1.2.0.\n* Add a preprocess directive `MMKV_DISABLE_CRYPT` to turn off MMKV encryption ability once and for all. If you integrate MMKV by source code, and if you are pretty sure encryption is not needed, you can turn that off to save some binary size.\n* The parameter `relativePath` (customizing a separate folder for an MMKV instance), has been renamed to `rootPath`. Making it clear that an absolute path is expected for that parameter.\n\n### iOS / macOS\n* `-[MMKV mmkvWithID: relativePath:]` is deprecated. Use `-[MMKV mmkvWithID: rootPath:]` instead. \n* Likewise, `-[MMKV mmkvWithID: cryptKey: relativePath:]` is deprecated. Use `-[MMKV mmkvWithID: cryptKey: rootPath:]` instead. \n\n## v1.2.0 / 2020-06-30\nThis is the second **major version** of MMKV. Everything you call is the same as the last version, while almost everything underneath has been improved. \n\n* **Reduce Memory Footprint**. We used to cache all key-values in a dictionary for efficiency. From now on we store the offset of each key-value inside the mmap-memory instead, **reducing memory footprint by almost half** for (non-encrypt) MMKV. And the accessing efficiency is almost the same as before. As for encrypted MMKV, we can't simply store the offset of each key-value, the relative encrypt info needs to be stored as well. That will be too much for small key-values. We only store such info for large key-values (larger than 256B).\n* **Improve Writeback Efficiency**. Thanks to the optimization above, we now can implement writeback by simply calling **memmove()** multiple times. Efficiency is increased and memory consumption is down.\n* **Optimize Small Key-Values**. Small key-values of encrypted MMKV are still cached in memory, as all the old versions did. From now on, the struct `MMBuffer` will try to **store small values in the stack** instead of in the heap, saving a lot of time from `malloc()` & `free()`. In fact, all primitive types will be store in the stack memory.\n\nAll of the improvements above are available to all supported platforms. Here are the additional changes for each platform.\n\n### iOS / macOS\n* **Optimize insert & delete**. Especially for inserting new values to **existing keys**, or deleting keys. We now use the UTF-8 encoded keys in the mmap-memory instead of live encoding from keys, cutting the cost of string encoding conversion.\n* Fix Xcode compile error on some projects.\n* Drop the support of iOS 8. `thread_local` is not available on iOS 8. We choose to drop support instead of working around because iOS 8's market share is considerably small.\n\n### POSIX\n* It's known that GCC before 5.0 doesn't support C++17 standard very well. You should upgrade to the latest version of GCC to compile MMKV.\n\n## v1.1.2 / 2020-05-29\n\n### Android / iOS & macOS / Windows / POSIX\n\n* Fix a potential crash after `trim()` a multi-process MMKV instance.\n* Improve `clearAll()` a bit.\n\n## v1.1.1 / 2020-04-13\n\n### iOS / macOS\n\n* Support WatchOS.\n* Rename `+[MMKV onExit]` to `+[MMKV onAppTerminate]`, to avoid naming conflict with some other OpenSource projects.\n* Make background write protection much more robust, fix a potential crash when writing meta info in background.\n* Fix a potential data corruption bug when writing a UTF-8 (non-ASCII) key.\n\n### Android\n\n* Fix a crash in the demo project when the App is hot reloaded.\n* Improve wiki & readme to recommend users to init & destruct MMKV in the `Application` class instead of the `MainActivity` class.\n\n### POSIX\n* Fix two compile errors with some compilers.\n\n## v1.1.0 / 2020-03-24\nThis is the first **major breaking version** ever since MMKV was made public in September 2018, introducing bunches of improvement. Due to the Covid-19, it has been delayed for about a month. Now it's finally here! \n\n* **Improved File Recovery Strategic**. We store the CRC checksum & actual file size on each sync operation & full write back, plus storing the actual file size in the same file(aka the .crc meta file) as the CRC checksum. Base on our usage inside WeChat on the iOS platform, it cuts the file **corruption rate down by almost half**.\n* **Unified Core Library**. We refactor the whole MMKV project and unify the cross-platform Core library. From now on, MMKV on iOS/macOS, Android, Windows all **share the same core logic code**. It brings many benefits such as reducing the work to fix common bugs, improvements on one platform are available to other platforms immediately, and much more.\n* **Supports POSIX Platforms**. Thanks to the unified Core library, we port MMKV to POSIX platforms easily.\n* **Multi-Process Access on iOS/macOS**. Thanks to the unified Core library, we add multi-process access to iOS/macOS platforms easily.\n* **Efficiency Improvement**. We make the most of armv8 ability including the AES & CRC32 instructions to tune **encryption & error checking speed up by one order higher** than before on armv8 devices. There are bunches of other speed tuning all around the whole project.\n\nHere are the old-style change logs of each platform.\n\n### iOS / macOS\n* Adds **multi-process access** support. You should initialize MMKV by calling `+[MMKV initializeMMKV: groupDir: logLevel:]`, passing your **app group id**. Then you can get a multi-process instance by calling `+[MMKV mmkvWithID: mode:]` or `+[MMKV mmkvWithID: cryptKey: mode:]`, accessing it cross your app & your app extensions.\n* Add **inter-process content change notification**. You can get MMKV changes notification of other processes by implementing `- onMMKVContentChange:` of `` protocol.\n* **Improved File Recovery Strategic**. Cuts the file corruption rate down by almost half. Details are above.\n* **Efficiency Improvement**. Encryption & error checking speed are up by one order higher on armv8 devices(aka iDevice including iPhone 5S and above). Encryption on armv7 devices is improved as well. Details are ahead.\n* Other speed improvements. Refactor core logic using **MRC**, improve std::vector `push_back()` speed by using **move constructors** & move assignments.\n* `+[MMKV setMMKVBasePath:]` & `+[MMKV setLogLevel:]` are marked **deprecated**. You should use `+[MMKV initializeMMKV:]` or `+[MMKV initializeMMKV: logLevel:]` instead.\n* The `MMKVLogLevel` enum has been improved in Swift. It can be used like `MMKVLogLevel.info` and so on.\n\n### Android\n* **Improved File Recovery Strategic**. Cuts the file corruption rate down by almost half. Details are above.\n* **Efficiency Improvement**. Encryption & error checking speed are up by one order higher on armv8 devices with the `arm64-v8a` abi. Encryption on `armeabi` & `armeabi-v7a` is improved as well. Details are ahead.\n* Add exception inside core encode & decode logic, making MMKV much more robust.\n* Other speed improvements. Improve std::vector `push_back()` speed by using **move constructors** & move assignments.\n\n### Windows\n* **Improved File Recovery Strategic**. Cuts the file corruption rate down by almost half. Details are above.\n* Add exception inside core encode & decode logic, making MMKV much more robust.\n* Other speed improvements. Improve std::vector `push_back()` speed by using **move constructors** & move assignments.\n\n### POSIX\n* Most things actually work! We have tested MMKV on the latest version of Linux(Ubuntu, Arch Linux, CentOS, Gentoo), and Unix(macOS, FreeBSD, OpenBSD) on the time v1.1.0 is released.\n\n## v1.0.24 / 2020-01-16\n\n### iOS / macOS\nWhat's new \n\n* Fix a bug that MMKV will fail to save any key-values after calling `-[MMKV clearMemoryCache]` and then `-[MMKV clearAll]`.\n* Add `+[MMKV initializeMMKV:]` for users to init MMKV in the main thread, to avoid an iOS 13 potential crash when accessing `UIApplicationState` in child threads.\n* Fix a potential crash when writing a uniquely constructed string.\n* Fix a performance slow down when acquiring MMKV instances too often.\n* Make the baseline test in MMKVDemo more robust to NSUserDefaults' caches.\n\n### Android\nWhat's new \n\n* Fix `flock()` bug on ashmem files in Android.\n* Fix a potential crash when writing a uniquely constructed string.\n* Fix a bug that the MMKVDemo might crash when running in a simulator.\n\n### Windows\n* Fix a potential crash when writing a uniquely constructed string or data.\n\n## v1.0.23 / 2019-09-03\n\n### iOS / macOS\nWhat's new \n\n* Fix a potential security leak on encrypted MMKV.\n\n### Android\nWhat's new \n\n* Fix a potential security leak on encrypted MMKV.\n* Fix filename bug when compiled on Windows environment.\n* Add option for decoding String Set into other `Set<>` classes other than the default `HashSet`, check `decodeStringSet()` for details.\n* Add `putBytes()` & `getBytes()`, to make function names more clear and consistent.\n* Add notification of content changed by other process, check the new `MMKVContentChangeNotification<>` interface & `checkContentChangedByOuterProcess()` for details.\n\n### Windows\nWhat's new \n\n* Fix a potential security leak on encrypted MMKV.\n* Fix `CriticalSection` init bug.\n\n## v1.0.22 / 2019-06-10\n\n### iOS / macOS\nWhat's new \n\n* Fix a bug that MMKV will corrupt while adding just one key-value, and reboot or clear memory cache.

Use them if you worry about disk / memory / fd usage.\n* Fix an issue that MMKV's file size might expand unexpectly large in some case.\n\nKnown Issues\n\n* Setting `nil` value to reset a key will be ignored. Use `remove` instead.\n\n### Android\nWhat's new \n\n* Add static linked of libc++ to trim AAR size. Use it when there's no other lib in your App embeds `libc++_shared.so`. Or if you already have an older version of `libc++_shared.so` that doesn't agree with MMKV. \nAdd `implementation 'com.tencent:mmkv-static:1.0.13'` to your App's gradle setting to integrate.\n* Special chars like `/` are supported in MMKV now. The file name of MMKV with special mmapID will be encoded with md5 and stored in seperate folder.\n* Add **callback** for MMKV error handling. You can make MMKV to recover instead of discard when crc32 check fail happens.\n* Add `trim` and `close` operation. Generally speaking they are not necessary in daily usage.

MMKV does type erasure while storing values. That means it's hard for MMKV to do value-type-checking, if not impossible.\n\n### Android \nWhat's new \n\n* Some performance improvement\n\nKnown Issues\n\n* Getting an MMKV instance with mmapID that contains `/` may fail. \nMMKV uses mmapID as its filename, so don't contain any `/` inside mmapID.\n* Storing a value of `type A` and getting by `type B` may not work. \nMMKV does type erasure while storing values. That means it's hard for MMKV to do value-type-checking, if not impossible.\n* `registerOnSharedPreferenceChangeListener` not supported. \nThis is intended. We believe doing data-change-listener inside a storage framework smells really bad to us.

After full testing, `dev` will be merged to `master` branch for the next release.\n\t2. **You are recommended to submit bugfix or feature PR on `dev` branch.**\n3. `hotfix` branch. \n\t1. It is the latest tag version for hot fix. If we accept your pull request, we may just tag with version number `1.1.1`, `1.2.3`.\n\t2. **Only submit urgent PR on `hotfix` branch for next specific release.**\n\nNormal bugfix or feature request should be submitted to `dev` branch. After full testing, we will merge them to `master` branch for the next release. \n\nIf you have some urgent bugfixes on a published version, but the `master` branch have already far away with the latest tag version, you can submit a PR on hotfix. And it will be cherry picked to `dev` branch if it is possible.\n\n```\nmaster\n ↑\ndev <--- hotfix PR\n ↑ \nfeature/bugfix PR\n``` \n\n### Make Pull Requests\nThe code team will monitor all pull request, we run some code check and test on it. After all tests passed, we will accecpt this PR. But it won't merge to `master` branch at once, which have some delay.\n\nBefore submitting a pull request, please make sure the followings are done:\n\n1. Fork the repo and create your branch from `master` or `hotfix`.\n2. Update code or documentation if you have changed APIs.\n3. Add the copyright notice to the top of any new files you've added.\n4. Check your code lints and checkstyles.\n5. Test and test again your code.\n6. Now, you can submit your pull request on `dev` or `hotfix` branch.\n\n## Code Style Guide\nWe choose the `LLVM code style` for MMKV project, with the specialization that using 4 space width for indent, and using tab for ObjC indentation. To make things simple, we have already defined our code style inside [clang-format](./.clang-format). \nYou can just run `make format_code` on top directory to format all your changes before committing them. \n\nAdditionly, check out [Code Style](./Android/MMKV/checkstyle.xml) for Java and Android.\n\n## License\nBy contributing to MMKV, you agree that your contributions will be licensed\nunder its [BSD LICENSE](./LICENSE.txt)\n" }, { "path": "Core/.gitignore", "content": "include/\n" }, { "path": "Core/CMakeLists.txt", "content": "#\n# Tencent is pleased to support the open source community by making\n# MMKV available.\n#\n# Copyright (C) 2019 THL A29 Limited, a Tencent company.\n# All rights reserved.\n#\n# Licensed under the BSD 3-Clause License (the \"License\"); you may not use\n# this file except in compliance with the License.

Added `onMMKVContentLoadSuccessfully` callback.\r\n* **Feature:** Added `MMKVConfig` for all-in-one instance configuration.\r\n* **Feature:** Added `defaultMMKVWithConfig()` for creating the default instance with full configuration.\r\n* **Fix:** Robust check on encryption mode.\r\n* Merge ashmem size with `expectedCapacity`.\r\n\r\n## v2.3.0 / 2025-12-03\r\n\r\nThis release introduces **AES-256 encryption** for enhanced security.\r\n\r\n* **Feature:** Added **AES-256 encryption** functionality. To upgrade an existing encrypted MMKV instance to AES-256, first load it using the old key. Then, call the `reKey()` method with the new key and set the `aes256` parameter to `true`, e.g., `reKey(newKey, true)`. After this, you should use the new key for all future loads of this instance.\r\n* **Fix:** Resolved a crash that occurred when loading an empty file in `ReadOnly` mode.\r\n* **Fix:** Added protection against the `weakly_canonical()` exception caused by an invalid file path.\r\n* **Fix:** Fixed an issue where the file size could change during multi-process loading.\r\n* **Fix:** Corrected a bug where a single key could be overridden incorrectly when upgrading from a v1.1.x version.\r\n\r\n## v2.2.4 / 2025-09-25\r\n* Improve the performance of MMBuffer a little bit in some cases.\r\n\r\n## v2.2.3 / 2025-08-20\r\n* Keep up with Core library v2.2.3.\r\n\r\n## v2.2.2 / 2025-05-08\r\nThis is a hot fix version mainly **for Android/Linux platforms**. It’s highly recommended for v2.2.0~v2.2.1 users.\r\n* Improve file lock consistency for Mayfly FD MMKV instances.\r\n\r\n## v2.2.1 / 2025-04-25\r\n* Add `importFrom()`.\r\n\r\n## v2.2.0 / 2025-04-24\r\nWe introduce the **Mayfly FD** (short-lived file descriptor) enhancement, reducing MMKV's fd footprint by half and more. For a single-process mode MMKV instance, the fd footprint is reduced to zero (except Android/OHOS, details below). For a multi-process mode MMKV instance, the fd footprint is reduced by half, for we still need a long-lived fd to inter-process lock the shared memory.\r\n* Add **Mayfly FD** (short-lived file descriptor) enhancement. Reduce the fd footprint by half. For a single-process mode MMKV instance, we still need a long-lived fd to support the **legacy name upgrading**. In the far future, when all legacy names have been upgraded, we might drop the long-lived fd like other platforms.\r\n* Improve multi-process access efficiency by about 20%.\r\n* Add `checkExist()` to check if a MMKV instance exists on disk.\r\n* Drop deprecated armv7 AES hardware acceleration.\r\n* Drop `checkProcessMode()`, it’s never been used.\r\n* Improve obfuscation configuration with relative path.\r\n\r\n## v2.1.0 / 2025-02-18\r\n* **Breaking change**: Migrate legacy MMKV in a custom directory to normal MMKV. Historically Android/OHOS mistakenly use mmapKey as mmapID, which will be problematic with the `NameSpace` feature. Starting from v2.1.0, MMKV will try to migrate them back to normal when possible. \r\n It's highly recommended that you **upgrade to v2.0.2 first** with **forward support** of normal MMKV in a custom directory.\r\n* Supports using MMKV directly in C++ code.\r\n* Improve inter-process locking by using `F_OFD_SETLK` instead of `F_SETLK`.\r\n* Improve directory creation on `ReadOnly` mode.\r\n* Add *experimental* protection from bad disk records of MMKV files.\r\n* Fix FileLock not being unlocked on destruction.\r\n\r\n## v2.0.2 / 2024-12-27\r\n* Obfuscation fully supported.\r\n* Use atomic file rename on OHOS.\r\n* Add forward support for the correct filename with a custom root path.\r\n\r\n## v2.0.1 / 2024-11-12\r\n* Fix a bug that MMKV might become dead-locked for other threads after `decodeStringSet()` / `decodeNumberSet` / `decodeBoolSet` or decoding `TypedArray`.\r\n\r\n## v2.0.0 / 2024-10-21\r\n* Support obfuscation. For the time being, you will have to manually copy the content of MMKV's [consumer-rules.txt](https://github.com/Tencent/MMKV/blob/master/OpenHarmony/MMKV/consumer-rules.txt) into your App's obfuscation-rules.txt.\r\n* Support read-only mode.\r\n* Add add log/error/content-change callback for Flutter & ArtTS\r\n\r\n## v1.3.9 / 2024-07-26\r\n* Fix a data corruption bug on an encrypted MMKV with only one key value stored.\r\n* Make encryption more resilient from brute force cracking.\r\n\r\n## v1.3.7 / 2024-07-12\r\n* Add support of Flutter on HarmonyOS NEXT.\r\n\r\n## v1.3.6 / 2024-07-05\r\n* Fix a bug that a `String` value might get truncated on encoding.\r\n* MMKV returns `undefined` when a key does not exist, previously a default value of the type (`false` for `boolean`, `0` for `number`, etc) is returned.\r\n* Add the feature to encode/decode a `float` value.\r\n* Add the feature to encode/decode a `TypedArray` value.\r\n* Support encoding a part of an `ArrayBuffer`.\r\n\r\n## v1.3.5 / 2024-04-24\r\nFix a bug in `MMKV.initialize()` that fails to handle the optional parameter _logLevel_.\r\n\r\n## v1.3.4 / 2024-04-17\r\n\r\nThe first official HarmonyOS NEXT package of MMKV. Most things actually work!\r\n" }, { "path": "OpenHarmony/MMKV/Index.ets", "content": "export { MMKV } from \"./src/main/ets/utils/MMKV\";\nexport { MMKVLogLevel } from \"./src/main/ets/utils/MMKVLogLevel\";\nexport { NativeBuffer } from \"./src/main/ets/utils/NativeBuffer\";\nexport { MMKVHandler, MMKVRecoverStrategic } from \"./src/main/ets/utils/MMKVHandler\";\nexport { MMKVConfig } from \"./src/main/ets/utils/MMKVConfig\";\n" }, { "path": "OpenHarmony/MMKV/LICENSE", "content": "Tencent is pleased to support the open source community by making MMKV available. \nCopyright (C) 2018 THL A29 Limited, a Tencent company.

It's now available on **HarmonyOS NEXT**.\r\n\r\n# MMKV for HarmonyOS NEXT\r\n\r\n## Features\r\n\r\n* **Efficient**. MMKV uses mmap to keep memory synced with file, and protobuf to encode/decode values, making the most of native platform to achieve best performance.\r\n * **Multi-Process concurrency**: MMKV supports concurrent read-read and read-write access between processes.\r\n\r\n* **Easy-to-use**. You can use MMKV as you go. All changes are saved immediately, no `sync`, no `flush` calls needed.\r\n\r\n* **Small**.\r\n * **A handful of files**: MMKV contains process locks, encode/decode helpers and mmap logics and nothing more. It's really tidy.\r\n * **About 600K in binary size**: MMKV adds about 600K per architecture on App size, and much less when zipped (HAR/HAP).\r\n\r\n\r\n## Getting Started\r\n\r\n### Prerequisites\r\n\r\n* Apps using MMKV can target: HarmonyOS Next (3.0.0.13) or later (API 12).\r\n* ARM64 & x86_64 architecture.\r\n* DevEco Studio NEXT Developer Beta1 (5.0.3.100) or later.\r\n\r\n### Installation via OHPM:\r\nThis is the fastest and recommended way to add MMKV to your project.\r\n```bash\r\nohpm install @tencent/mmkv\r\n```\r\nOr, you can add it to your project manually.\r\n* Add the following lines to `oh-package.json5` on your app module.\r\n\r\n ```json\r\n \"dependencies\": {\r\n \"@tencent/mmkv\": \"~2.4.0\",\r\n }\r\n ```\r\n* Then run\r\n \r\n ```bash\r\n ohpm install\r\n ```\r\n\r\nFor additional installation methods, checkout the [wiki](https://github.com/Tencent/MMKV/wiki/ohos_setup#installation).\r\n\r\n### Setup\r\nYou can use MMKV as you go. All changes are saved immediately, no `sync`, no `apply` calls needed. \r\nSetup MMKV on App startup, say your `EntryAbility.onCreate()` function, add these lines:\r\n\r\n```js\r\nimport { MMKV } from '@tencent/mmkv';\r\n\r\nexport default class EntryAbility extends UIAbility {\r\n onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void {\r\n let appCtx = this.context.getApplicationContext();\r\n let mmkvRootDir = MMKV.initialize(appCtx);\r\n console.info('mmkv rootDir: ', mmkvRootDir);\r\n ……\r\n }\r\n```\r\n\r\n### CRUD Operations\r\n\r\n* MMKV has a global instance, that can be used directly:\r\n\r\n ```js\r\n import { MMKV } from '@tencent/mmkv';\r\n \r\n let mmkv = MMKV.defaultMMKV();\r\n mmkv.encodeBool('bool', true);\r\n console.info('bool = ', mmkv.decodeBool('bool'));\r\n \r\n mmkv.encodeInt32('int32', Math.pow(2, 31) - 1);\r\n console.info('max int32 = ', mmkv.decodeInt32('int32'));\r\n \r\n mmkv.encodeInt64('int', BigInt(2**63) - BigInt(1));\r\n console.info('max int64 = ', mmkv.decodeInt64('int'));\r\n \r\n let str: string = 'Hello OpenHarmony from MMKV';\r\n mmkv.encodeString('string', str);\r\n console.info('string = ', mmkv.decodeString('string'));\r\n\r\n let arrayBuffer: ArrayBuffer = StringToArrayBuffer('Hello OpenHarmony from MMKV with bytes');\r\n mmkv.encodeBytes('bytes', arrayBuffer);\r\n let bytes = mmkv.decodeBytes('bytes');\r\n console.info('bytes = ', ArrayBufferToString(bytes));\r\n\r\n let arr = new Uint8Array([0, 255, 1, 255]);\r\n mmkv.encodeTypedArray('uint8-array', arr);\r\n let newUI8Arr = kv.decodeUint8Array('uint8-array');\r\n console.info('uint8-array = ', newUI8Arr);\r\n ```\r\n\r\n As you can see, MMKV is quite easy to use.\r\n \r\n* **Deleting & Querying**:\r\n\r\n ```js\r\n mmkv.removeValueForKey('bool');\r\n console.info('contains \"bool\"', mmkv.containsKey('bool'));\r\n\r\n mmkv.removeValuesForKeys(['int32', 'int']);\r\n console.info('all keys: ', mmkv.allKeys().join());\r\n ```\r\n\r\n* If different modules/logic need **isolated storage**, you can also create your own MMKV instance separately:\r\n\r\n ```js\r\n var mmkv = MMKV.mmkvWithID('test');\r\n mmkv.encodeBool('bool', true);\r\n console.info('bool = ', mmkv.decodeBool('bool'));\r\n ```\r\n\r\n* If **multi-process accessing** is needed，you can set `MMKV.MULTI_PROCESS_MODE` on MMKV initialization:\r\n\r\n ```dart\r\n var mmkv = MMKV.mmkvWithID('test-multi-process', MMKV.MULTI_PROCESS_MODE);\r\n mmkv.encodeBool('bool', true);\r\n console.info('bool = ', mmkv.decodeBool('bool'));\r\n ```\r\n\r\n### Supported Types\r\n* Primitive Types:\r\n - `boolean, number, bigint, string`\r\n\r\n* Classes & Collections:\r\n - `boolean[], number[], string[], ArrayBuffer, TypedArray`\r\n\r\n### Log\r\n\r\n* By default, MMKV prints log to hilog, which is not convenient for diagnosing online issues. \r\nYou can setup MMKV **log redirecting** on App startup on the **native** interface of MMKV. \r\nCheckout how to do it on [C++](https://github.com/Tencent/MMKV/wiki/posix_tutorial#logs).\r\nDue to the current limitation of NAPI runtime, we **can't efficiently** redirect log to the JavaScript side.\r\n\r\n* You can turn off MMKV's logging once and for all on initialization (which we strongly disrecommend). \r\n\r\n ```js\r\n import { MMKV, MMKVLogLevel } from '@tencent/mmkv';\r\n\r\n MMKV.initialize(appCtx, MMKVLogLevel.None);\r\n ```\r\n\r\n### Encryption\r\n* By default MMKV stores all key-values in plain text on file, relying on Android's/iOS's sandbox to make sure the file is encrypted. Should you worry about information leaking, you can choose to encrypt MMKV.\r\n\r\n ```js\r\n let encryptKey = 'MyEncryptKey';\r\n let mmkv = MMKV.mmkvWithID('test-encryption', MMKV.SINGLE_PROCESS_MODE, encryptKey);\r\n ```\r\n\r\n* You can change the encryption key later as you like. You can also change an existing MMKV instance from encrypted to unencrypted, or vice versa.\r\n\r\n ```js\r\n // an unencrypted MMKV instance\r\n let mmkv = MMKV.mmkvWithID('test-encryption');\r\n\r\n // change from unencrypted to encrypted with AES-128 key length\r\n mmkv.reKey('Key_seq_1');\r\n\r\n // change encryption key with AES-258 key length\r\n mmkv.reKey('Key_Seq_Very_Looooooooong', true);\r\n\r\n // change from encrypted to unencrypted\r\n kmmkv.reKey();\r\n ```\r\n \r\n### Customize location\r\n* By default, MMKV stores file inside `$(FilesDir)/mmkv/`. You can customize MMKV's **root directory** on App startup:\r\n\r\n ```js\r\n let appCtx = this.context.getApplicationContext();\r\n let rootDir = appCtx.filesDir + '/mmkv_2';\r\n let cacheDir = appCtx.cacheDir;\r\n MMKV.initializeWithPath(rootDir, cacheDir);\r\n ```\r\n\r\n* You can even customize any MMKV instance's location:\r\n\r\n ```js\r\n let appCtx = this.context.getApplicationContext();\r\n let rootDir = appCtx.filesDir + '/mmkv_3';\r\n var mmkv = MMKV.mmkvWithID('testCustomDir', MMKV.SINGLE_PROCESS_MODE, null, rootDir);\r\n ```\r\n **Note:** It's recommended to store MMKV files **inside** your App's sandbox path. **DO NOT** store them on external storage(aka SD card).\r\n\r\n### Additional docs\r\nFor additional documents, checkout the [wiki](https://github.com/Tencent/MMKV/wiki/ohos_setup).\r\n\r\n## License\r\nMMKV is published under the BSD 3-Clause license.

It's currently available on **Android**, **iOS/macOS**, **Windows**, **POSIX** and **HarmonyOS NEXT**.\r\n\r\n# MMKV for Android\r\n\r\n## Features\r\n\r\n* **Efficient**. MMKV uses mmap to keep memory synced with files, and protobuf to encode/decode values, making the most of Android to achieve the best performance.\r\n * **Multi-Process concurrency**: MMKV supports concurrent read-read and read-write access between processes.\r\n\r\n* **Easy-to-use**. You can use MMKV as you go. All changes are saved immediately, no `sync`, no `apply` calls needed.\r\n\r\n* **Small**.\r\n * **A handful of files**: MMKV contains process locks, encode/decode helpers and mmap logics, and nothing more. It's really tidy.\r\n * **About 50K in binary size**: MMKV adds about 50K per architecture on App size, and much less when zipped (APK).\r\n\r\n\r\n## Getting Started\r\n\r\n### Installation Via Maven\r\nAdd the following lines to `build.gradle` on your app module:\r\n\r\n```gradle\r\ndependencies {\r\n implementation 'com.tencent:mmkv:2.4.0'\r\n // replace \"2.4.0\" with any available version\r\n}\r\n```\r\n\r\nStarting from v2.0.0, MMKV **no longer supports 32-bit** arch and API level 22 or 21, if you want 32-bit or API level 21~22, use v1.3.x LTS series. \r\n\r\nFor other installation options, see [Android Setup](https://github.com/Tencent/MMKV/wiki/android_setup).\r\n\r\n### Quick Tutorial\r\nYou can use MMKV as you go. All changes are saved immediately, no `sync`, no `apply` calls needed. \r\nSetup MMKV on App startup, say your `Application` class, add these lines:\r\n\r\n```Java\r\npublic void onCreate() {\r\n super.onCreate();\r\n\r\n String rootDir = MMKV.initialize(this);\r\n System.out.println(\"mmkv root: \" + rootDir);\r\n //……\r\n}\r\n```\r\n\r\nMMKV has a global instance, that can be used directly:\r\n\r\n```Java\r\nimport com.tencent.mmkv.MMKV;\r\n \r\nMMKV kv = MMKV.defaultMMKV();\r\n\r\nkv.encode(\"bool\", true);\r\nboolean bValue = kv.decodeBool(\"bool\");\r\n\r\nkv.encode(\"int\", Integer.MIN_VALUE);\r\nint iValue = kv.decodeInt(\"int\");\r\n\r\nkv.encode(\"string\", \"Hello from mmkv\");\r\nString str = kv.decodeString(\"string\");\r\n```\r\n\r\nMMKV also supports **Multi-Process Access**. Full tutorials can be found here [Android Tutorial](https://github.com/Tencent/MMKV/wiki/android_tutorial).\r\n\r\n## Performance\r\nWriting random `int` for 1000 times, we get this chart: \r\n![](https://github.com/Tencent/MMKV/wiki/assets/profile_android_mini.png) \r\nFor more benchmark data, please refer to [our benchmark](https://github.com/Tencent/MMKV/wiki/android_benchmark).\r\n\r\n# MMKV for iOS/macOS\r\n\r\n## Features\r\n\r\n* **Efficient**. MMKV uses mmap to keep memory synced with files, and protobuf to encode/decode values, making the most of iOS/macOS to achieve the best performance.\r\n \r\n* **Easy-to-use**. You can use MMKV as you go, no configurations are needed. All changes are saved immediately, no `synchronize` calls are needed.\r\n\r\n* **Small**.\r\n * **A handful of files**: MMKV contains encode/decode helpers and mmap logics and nothing more. It's really tidy.\r\n * **Less than 30K in binary size**: MMKV adds less than 30K per architecture on App size, and much less when zipped (IPA).\r\n\r\n## Getting Started\r\n\r\n### Installation Via CocoaPods:\r\n 1. Install [CocoaPods](https://guides.CocoaPods.org/using/getting-started.html);\r\n 2. Open the terminal, `cd` to your project directory, run `pod repo update` to make CocoaPods aware of the latest available MMKV versions;\r\n 3. Edit your Podfile, add `pod 'MMKV'` to your app target;\r\n 4. Run `pod install`;\r\n 5. Open the `.xcworkspace` file generated by CocoaPods;\r\n 6. Add `#import ` to your source file and we are done.\r\n\r\nFor other installation options, see [iOS/macOS Setup](https://github.com/Tencent/MMKV/wiki/iOS_setup).\r\n\r\n### Quick Tutorial\r\nYou can use MMKV as you go, no configurations are needed. All changes are saved immediately, no `synchronize` calls are needed.\r\nSetup MMKV on App startup, in your `-[MyApp application: didFinishLaunchingWithOptions:]`, add these lines:\r\n\r\n```objective-c\r\n- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {\r\n // init MMKV in the main thread\r\n [MMKV initializeMMKV:nil];\r\n\r\n //...\r\n return YES;\r\n}\r\n```\r\n\r\nMMKV has a global instance, that can be used directly:\r\n\r\n```objective-c\r\nMMKV *mmkv = [MMKV defaultMMKV];\r\n \r\n[mmkv setBool:YES forKey:@\"bool\"];\r\nBOOL bValue = [mmkv getBoolForKey:@\"bool\"];\r\n \r\n[mmkv setInt32:-1024 forKey:@\"int32\"];\r\nint32_t iValue = [mmkv getInt32ForKey:@\"int32\"];\r\n \r\n[mmkv setString:@\"hello, mmkv\" forKey:@\"string\"];\r\nNSString *str = [mmkv getStringForKey:@\"string\"];\r\n```\r\n\r\nMMKV also supports **Multi-Process Access**. Full tutorials can be found [here](https://github.com/Tencent/MMKV/wiki/iOS_tutorial).\r\n\r\n## Performance\r\nWriting random `int` for 10000 times, we get this chart: \r\n![](https://github.com/Tencent/MMKV/wiki/assets/profile_mini.png) \r\nFor more benchmark data, please refer to [our benchmark](https://github.com/Tencent/MMKV/wiki/iOS_benchmark).\r\n\r\n\r\n# MMKV for Windows\r\n\r\n## Features\r\n\r\n* **Efficient**. MMKV uses mmap to keep memory synced with files, and protobuf to encode/decode values, making the most of Windows to achieve the best performance.\r\n * **Multi-Process concurrency**: MMKV supports concurrent read-read and read-write access between processes.\r\n\r\n* **Easy-to-use**.

It's really tidy.\r\n * **About 10K in binary size**: MMKV adds about 10K on application size, and much less when zipped.\r\n\r\n\r\n## Getting Started\r\n\r\n### Installation Via Source\r\n1. Getting source code from git repository:\r\n \r\n ```\r\n git clone https://github.com/Tencent/MMKV.git\r\n ```\r\n \r\n2. Add `Core/core.vcxproj` to your solution;\r\n3. Add `MMKV` project to your project's dependencies;\r\n4. Add `$(OutDir)include` to your project's `C/C++` -> `General` -> `Additional Include Directories`;\r\n5. Add `$(OutDir)` to your project's `Linker` -> `General` -> `Additional Library Directories`;\r\n6. Add `mmkv.lib` to your project's `Linker` -> `Input` -> `Additional Dependencies`;\r\n7. Add `#include ` to your source file and we are done.\r\n\r\n\r\nnote: \r\n\r\n1. MMKV is compiled with `MT/MTd` runtime by default. If your project uses `MD/MDd`, you should change MMKV's setting to match your project's (`C/C++` -> `Code Generation` -> `Runtime Library`), or vice versa.\r\n2. MMKV is developed with Visual Studio 2017, change the `Platform Toolset` if you use a different version of Visual Studio.\r\n\r\nFor other installation options, see [Windows Setup](https://github.com/Tencent/MMKV/wiki/windows_setup).\r\n\r\n### Quick Tutorial\r\nYou can use MMKV as you go. All changes are saved immediately, no `sync`, no `save` calls needed. \r\nSetup MMKV on App startup, say in your `main()`, add these lines:\r\n\r\n```C++\r\n#include \r\n\r\nint main() {\r\n std::wstring rootDir = getYourAppDocumentDir();\r\n MMKV::initializeMMKV(rootDir);\r\n //...\r\n}\r\n```\r\n\r\nMMKV has a global instance, that can be used directly:\r\n\r\n```C++\r\nauto mmkv = MMKV::defaultMMKV();\r\n\r\nmmkv->set(true, \"bool\");\r\nstd::cout << \"bool = \" << mmkv->getBool(\"bool\") << std::endl;\r\n\r\nmmkv->set(1024, \"int32\");\r\nstd::cout << \"int32 = \" << mmkv->getInt32(\"int32\") << std::endl;\r\n\r\nmmkv->set(\"Hello, MMKV for Windows\", \"string\");\r\nstd::string result;\r\nmmkv->getString(\"string\", result);\r\nstd::cout << \"string = \" << result << std::endl;\r\n```\r\n\r\nMMKV also supports **Multi-Process Access**. Full tutorials can be found here [Windows Tutorial](https://github.com/Tencent/MMKV/wiki/windows_tutorial).\r\n\r\n# MMKV for POSIX\r\n\r\n## Features\r\n\r\n* **Efficient**. MMKV uses mmap to keep memory synced with files, and protobuf to encode/decode values, making the most of POSIX to achieve the best performance.\r\n * **Multi-Process concurrency**: MMKV supports concurrent read-read and read-write access between processes.\r\n\r\n* **Easy-to-use**. You can use MMKV as you go. All changes are saved immediately, no `save`, no `sync` calls are needed.\r\n\r\n* **Small**.\r\n * **A handful of files**: MMKV contains process locks, encode/decode helpers and mmap logics, and nothing more. It's really tidy.\r\n * **About 7K in binary size**: MMKV adds about 7K on application size, and much less when zipped.\r\n\r\n\r\n## Getting Started\r\n\r\n### Installation Via CMake\r\n1. Getting source code from the git repository:\r\n \r\n ```\r\n git clone https://github.com/Tencent/MMKV.git\r\n ```\r\n2.

"flutter/mmkv/CHANGELOG.md", "content": "# MMKV for Flutter Change Log\n## v2.4.0 / 2026-03-18\n* **Feature:** Refactored the callback system into a unified `MMKVHandler` interface. Added `onMMKVContentLoadSuccessfully` callback.\n* **Feature:** Added `MMKVConfig` for all-in-one instance configuration.\n* **Feature:** Added `defaultMMKV(config)` for creating the default instance with full configuration.\n* **Fix:** Robust check on encryption mode.\n* Android: Fix `fcntl()` OFD lock failure on ashmem.\n* iOS: Fixed a memory leak on getting `NameSpace` instance.\n\n## v2.3.0 / 2025-12-03\nThis release is a **breaking change** and introduces **AES-256 encryption** for enhanced security.\n* **Feature:** Added **AES-256 encryption** functionality. To upgrade an existing encrypted MMKV instance to AES-256, first load it using the old key. Then, call the `reKey()` method with the new key and set the `aes256` parameter to `true`, e.g., `reKey(newKey, aes256: true)`. After this, you should use the new key for all future loads of this instance.\n* **Fix:** Resolved a crash that occurred when loading an empty file in `ReadOnly` mode.\n* **Fix:** Added protection against the `weakly_canonical()` exception caused by an invalid file path.\n* **Fix:** Fixed an issue where the file size could change during multi-process loading.\n* **Fix:** Corrected a bug where a single key could be overridden incorrectly when upgrading from a v1.1.x version.\n\n## v2.2.4 / 2025-09-25\nThis is a hotfix release mainly for iOS/macOS CocoaPods users.\n\n* Improve the performance of MMBuffer a little bit in some cases.\n* iOS/macOS: Make MMKV and MMKVCore podspec define modules.\n\n## v2.2.3 / 2025-08-20\nThis is a feature release that brings **full desktop support to Flutter**.\n* **Added Full Desktop Support**: MMKV for Flutter now officially supports **Windows**, **macOS**, and **Linux**.\n* **Example App**: The example application has been updated to run on all new desktop platforms.\n\n## v2.2.2 / 2025-05-08\nThis is a hot fix version mainly **for Android platforms**. It’s highly recommended for v2.2.0~v2.2.1 users.\n* Improve file lock consistency for Mayfly FD MMKV instances.\n* Fix a potential Android ANR on multi-process mode MMKV init/creation.\n\n## v2.2.1 / 2025-4-25\n* Add `importFrom()`.\n* Fix Android initialize bug.\n\n## v2.2.0 / 2025-04-24\n* Add `checkExist()`.\n* Add `isFileValid()`.\n* Add `groupPath()` for iOS.\n* Reduce file descriptor usage by a half and more.\n* Improve multi-process access efficiency by about 20%.\n* Fix `checkContentChangedByOuterProcess()` not working bug.\n\n## v2.1.1 / 2025-03-06\nThis is a **critical hotfix** for v2.1.0. It's highly recommended to upgrade as soon as possible.\n* Fix a bug that MMKV instance from non-namespace fails to create.\n\n## v2.1.0 / 2025-02-18\n* **Breaking change**: Migrate legacy MMKV in a custom directory to normal MMKV. Historically Android/OHOS mistakenly use mmapKey as mmapID, which will be problematic with the `NameSpace` feature. Starting from v2.1.0, MMKV will try to migrate them back to normal when possible. \n It's highly recommended that you **upgrade to v2.0.2 first** with **forward support** of normal MMKV in a custom directory.\n* Improve inter-process locking by using `F_OFD_SETLK` instead of `F_SETLK` in Android/OHOS.\n* Improve directory creation on `ReadOnly` mode.\n* Add protection from bad disk records of MMKV files.\n* Fix FileLock not being unlocked on destruction.\n\n## v2.0.2 / 2024-12-27\n* Add version limitation of < v2.1.0 on MMKV platform plugins.\n\n## v2.0.1 / 2024-10-25\n* Fix breaking changes on platform interface package.\n\n## v1.3.10 / 2024-10-25\n* Rollback some breaking changes on platform interface package.\n\n## v2.0.0 / 2024-10-21\n* Support read-only mode.\n* Add add log/error/content-change callback for Flutter & ArtTS\n* Bump Android minSdkVersion to 23.\n* Drop 32-bit arch support.\n\n## v1.3.9 / 2024-07-26\nThis will be **the last LTS release of MMKV for Flutter**.\n* Modify the dependency of native lib in a way that no Dart package update is needed for any LTS release in the future.\n* Fix a data corruption bug on an encrypted MMKV with only one key value stored.\n* Make encryption more resilient from brute force cracking.\n* Fix a bug that pthread_mutex is not being destroyed correctly.\n* Android: Use an alternative way to get the process name to avoid potential App review issues.\n* Android: Upgrade to NDK 26.3.11579264.\n\n## v1.3.8 / 2024-07-12\n* Add support for **HarmonyOS NEXT**.\n\n## v1.3.7 / 2024-07-08\n**Sync with Latest Android Native Binary:**\n\nThis Long Term Support (LTS) release primarily reintroduces support for the ARMv7 architecture and lowers the minimum SDK version requirement to 21. Please note that only critical bug fixes will be applied to the 1.3.x series. New features will be introduced in version 2.0 and later, which will discontinue support for 32-bit architectures and raise the minimum SDK version requirement to 23.\n\n## v1.3.6 / 2024-07-05\n* Android: MMKV will try to load libmmkv.so before Dart code, to reduce the error of loading library in Android.\n* Android: Use the latest ashmem API if possible.\n* Android: Use the latest API to get the device API level.\n\n## v1.3.5 / 2024-04-24\n* Migrate to federated plugins to avoid the iOS rename headache. From now on, no more renaming from `mmkv` to `mmkvflutter` is needed.\n* Bump iOS Deployment Target to iOS 12.\n* Bump Android minSdkVersion to 23.\n\n## v1.3.4 / 2024-03-15\n* Make `trim()` more robust in multi-process mode.\n\n## v1.3.3 / 2024-01-25\n* Add `removeStorage()` static method to safely delete underlying files of an MMKV instance.\n* Add protection from a potential crash of a multi-process MMKV loading due to the MMKV file not being valid.\n* Add back the lazy load feature. It was first introduced in v1.2.16. But it was rollbacked in v1.3.0 of potential ANR & file corruption. Now it's clear that the bug was caused by something else, it's time to bring it back.\n* **Optimize loading speed** by using shared inter-process lock unless there's a need to truncate the file size, which is rare.\n* Make these two lately added features **more robust**: customizing the initial file size & optimizing write speed when there's only one key inside MMKV.\n* On the Xcode 15 build, an App will crash on iOS 14 and below. Previously we have recommended some workarounds (check the v1.3.2 release note for details). Now you can use Xcode 15.1 to fix this issue.\n\n## v1.3.2 / 2023-11-20\nAmong most of the features added in this version, the credit goes to @kaitian521.\n\n* Add the feature of customizing the **initial file size** of an MMKV instance.\n* **Optimize write speed** when there's only one key inside MMKV, the new key is the same as the old one, and MMKV is in `SINGLE_PROCESS_MODE`.\n* **Optimize write speed** by overriding from the beginning of the file instead of append in the back, when there's zero key inside MMKV, and MMKV is in `SINGLE_PROCESS_MODE`.\n* Add the feature of `clearAll()` with keeping file disk space unchanged, **reducing the need to expand file size** on later insert & update operations. This feature is off by default, you will have to call it with relative params or newly added methods. \n* Add the feature of **comparing values before setting/encoding** on the same key.\n* Fix a potential bug that the MMKV file will be invalid state after a successful expansion but a failure `zeroFill()`, will lead to a crash.\n* Fix a potential crash due to other module/static lib turn-off **RTTI**, which will cause MMKV to fail to catch `std::exception`.\n* Fix several potential crash due to the MMKV file not being valid.\n* Android: Use the `-O2` optimization level by default, which will **reduce native lib size** and improve read/write speed a little bit.\n* Android: Experimantal use `@fastNative` annotation on `enableCompareBeforeCompare()` to speed up JNI call.\n* Turn-off mlock() protection in background on iOS 13+. We have **verified it on WeChat** that the protection is no longer needed from at least iOS 13. Maybe iOS 12 or older is also not needed, but we don't have the chance to verify that because WeChat no longer supports iOS 12.\n\n#### Known Issue\n* On Xcode 15 build, App will crash on iOS 14 and below. The bug is introduced by Apple's new linker. The official solutions provided by Apple are either:\n * Drop the support of iOS 14.\n * Add `-Wl,-weak_reference_mismatches,weak` or `-Wl,-ld_classic` options to the `OTHER_LDFLAGS` build setting of Xcode 15. Note that these options are **not recognized** by older versions of Xcode.\n * Use older versions of Xcode, or **wait for Xcode 15.2**.\n\n## v1.3.1 / 2023-8-11\nThis is a hotfix version. It's **highly recommended** that v1.2.16 & v1.3.0 users upgrade as soon as possible.\n* Fix a critical bug that might cause multi-process MMKV corrupt. This bug was introduced in v1.2.16.\n* Add the ability to filter expired keys on `count()` & `allKeys()` methods when auto key expiration is turn on.\n* Reduce the `msync()` call on newly created MMKV instances.\n\n## v1.3.0 / 2023-06-14\n* Add auto key expiration feature. Note that this is a breaking change, once upgrade to auto expiration, the MMKV file is not valid for older versions of MMKV (v1.2.16 and below) to correctly operate.\n* Roll back the lazy load optimization due to reported ANR issues. It was introduced in v1.2.16.\n* The version is now the same as the MMKV native library.\n* Starting from v1.3.0, Flutter for Android will use `com.tencent:mmkv`. Previously it's `com.tencent:mmkv-static`. It's the same as `com.tencent:mmkv` starting from v1.2.11.\n\n## v1.2.17 / 2023-04-20\n* Optimization: The actual file content is lazy loaded now, saving time on MMKV instance creation, and avoiding lock waiting when a lot of instances are created at the same time.\n* Fix a bug when restoring a loaded MMKV instance the meta file might mistakenly report corrupted.\n* Fix a crash on decoding an empty list.\n* Remove deprecated dependence.\n* Make the script more robust to fix the iOS Flutter plugin name.\n* Keep up with MMKV native lib v1.2.16.\n\n## v1.2.16 / 2023-01-12\n* Reduce the privacy info needed to obtain android sdkInt, avoid unnecessary risk on Android App Review.\n* Log handler now handles all logs from the very beginning, especially the logs in initialization.\n* Log handler register method is now deprecated. It's integrated with initialize().\n* Keep up with MMKV native lib v1.2.15.\n\n## v1.2.15 / 2022-08-10\n* Fix a bug that `MMKV.decodeXXX()` may return invalid results in multi-process mode.\n* Upgrade to Flutter 3.0.\n* Keep up with MMKV native lib v1.2.14.\n\n## v1.2.14 / 2022-03-30\n* Replace the deprecated `device_info` package with `device_info_plus`.\n* Keep up with MMKV native lib v1.2.13.\n\n## v1.2.13 / 2022-01-17\n* Fix a bug that a subsequential `clearAll()` call may fail to take effect in multi-process mode.\n* Hide some OpenSSL symbols to prevent link-time symbol conflict, when an App somehow also static linking OpenSSL.\n* Upgrade Android `compileSdkVersion` & `targetSdkVersion` from `30` to `31`.\n* Keep up with MMKV native lib v1.2.12.\n\n## v1.2.12 / 2021-10-26\n* Add backup & restore ability.\n* Keep up with MMKV native lib v1.2.11.\n\n## v1.2.11 / 2021-06-25\n* Bug Fixed: When building on iOS, occasionally it will fail on symbol conflict with other libs. We have renamed all public native methods to avoid potential conflict.\n* Keep up with MMKV native lib v1.2.10.\n\n## v1.2.10 / 2021-05-26\n* Bug Fixed: When calling `MMKV.encodeString()` with an empty string value on Android, `MMKV.decodeString()` will return `null`.\n* Bug Fixed: After upgrading from Flutter 1.20+ to 2.0+, calling `MMKV.defaultMMKV()` on Android might fail to load, you can try calling `MMKV.defaultMMKV(cryptKey: '\\u{2}U')` instead.\n* Keep up with MMKV native lib v1.2.9, which drops the **armeabi** arch on Android.\n\n## v1.2.9 / 2021-05-06\n* Support null-safety.\n* Upgrade to Flutter 2.0.\n* Keep up with MMKV native lib v1.2.8, which migrates the Android Native Lib to Maven Central Repository.\n* Fix `MMKV.encodeString()` crash on iOS with an empty string value.\n\n### Known Issue\n* When calling `MMKV.encodeString()` with an empty string value on Android, `MMKV.decodeString()` will return `null`. This bug will be fixed in the next version of Android Native Lib. iOS does not have such a bug.\n\n## v1.2.8 / 2020-12-25\n* Keep up with MMKV native lib v1.2.7, which fix the `MMKV.sync(false)` not being asynchronous bug.\n* Fix `MMKV.defaultMMKV()` crash on iOS simulator.\n* Fix `MMKV.defaultMMKV(cryptKey)` not encrypted as expected bug on iOS.\n\n## v1.2.7 / 2020-11-27\nFix iOS symbol not found bug.\n\n## v1.2.6 / 2020-11-27\nThe first official flutter plugin of MMKV.

It's currently available on **Android** and **iOS**.\r\n\r\n# MMKV for Flutter\r\n\r\n## Features\r\n\r\n* **Efficient**. MMKV uses mmap to keep memory synced with file, and protobuf to encode/decode values, making the most of native platform to achieve best performance.\r\n * **Multi-Process concurrency**: MMKV supports concurrent read-read and read-write access between processes.\r\n\r\n* **Easy-to-use**. You can use MMKV as you go. All changes are saved immediately, no `sync`, no `apply` calls needed.\r\n\r\n* **Small**.\r\n * **A handful of files**: MMKV contains process locks, encode/decode helpers and mmap logics and nothing more. It's really tidy.\r\n * **About 100K in binary size**: MMKV adds about 100K per architecture on App size, and much less when zipped (apk/ipa).\r\n\r\n\r\n## Getting Started\r\n\r\n### Installation\r\nAdd the following lines to `pubspec.yaml` on your app module. Then run `flutter pub get`.\r\n\r\n```yaml\r\ndependencies:\r\n mmkv: \"^2.4.0\"\r\n```\r\n\r\nIf you already include MMKV native lib in your App, you need to upgrade to version newer than v2.0.0. \r\n\r\n#### iOS \r\nStarting from v1.3.5, there's **no need** to change the plugin name 'mmkv' to 'mmkvflutter'. You should remove the script (`fix_mmkv_plugin_name()`) previously added in your Podfile. \r\n\r\n#### Android \r\nIf you previously use `com.tencent.mmkv-static` or `com.tencent.mmkv-shared` in your Android App, you should move to `com.tencent.mmkv`.\r\nAnd if your App depends on any 3rd SDK that embeds `com.tencent.mmkv-static` or `com.tencent.mmkv-shared`, you can add this lines to your `build.gradle` to avoid conflict:\r\n\r\n```gradle\r\n dependencies {\r\n ...\r\n\r\n modules {\r\n module(\"com.tencent:mmkv-static\") {\r\n replacedBy(\"com.tencent:mmkv\", \"Using mmkv for flutter\")\r\n }\r\n module(\"com.tencent:mmkv-shared\") {\r\n replacedBy(\"com.tencent:mmkv\", \"Using mmkv for flutter\")\r\n }\r\n }\r\n }\r\n```\r\n\r\n### Setup\r\nYou can use MMKV as you go. All changes are saved immediately, no `sync`, no `apply` calls needed. \r\nSetup MMKV on App startup, say your `main()` function, add these lines:\r\n\r\n```dart\r\nimport 'package:mmkv/mmkv.dart';\r\n\r\nvoid main() async {\r\n\r\n // must wait for MMKV to finish initialization\r\n final rootDir = await MMKV.initialize();\r\n print('MMKV for flutter with rootDir = $rootDir');\r\n\r\n runApp(MyApp());\r\n}\r\n```\r\nNote that you have to **wait for MMKV to finish initialization** before accessing any MMKV instance.\r\n\r\n### CRUD Operations\r\n\r\n* MMKV has a global instance, that can be used directly:\r\n\r\n ```dart\r\n import 'package:mmkv/mmkv.dart';\r\n \r\n var mmkv = MMKV.defaultMMKV();\r\n mmkv.encodeBool('bool', true);\r\n print('bool = ${mmkv.decodeBool('bool')}');\r\n \r\n mmkv.encodeInt32('int32', (1<<31) - 1);\r\n print('max int32 = ${mmkv.decodeInt32('int32')}');\r\n \r\n mmkv.encodeInt('int', (1<<63) - 1);\r\n print('max int = ${mmkv.decodeInt('int')}');\r\n \r\n String str = 'Hello Flutter from MMKV';\r\n mmkv.encodeString('string', str);\r\n print('string = ${mmkv.decodeString('string')}');\r\n\r\n str = 'Hello Flutter from MMKV with bytes';\r\n var bytes = MMBuffer.fromList(Utf8Encoder().convert(str))!;\r\n mmkv.encodeBytes('bytes', bytes);\r\n bytes.destroy();\r\n\r\n bytes = mmkv.decodeBytes('bytes')!;\r\n print('bytes = ${Utf8Decoder().convert(bytes.asList()!)}');\r\n bytes.destroy();\r\n ```\r\n\r\n As you can see, MMKV is quite easy to use.\r\n \r\n **Note**: If you come across to failing to load `defaultMMKV()` **on Android** after **upgrading** Flutter from 1.20+ to 2.0+, you can try passing this encryption key `'\\u{2}U'` instead. \r\n\r\n ```dart\r\n var mmkv = MMKV.defaultMMKV(cryptKey: '\\u{2}U');\r\n ```\r\n \r\n* **Deleting & Querying**:\r\n\r\n ```dart\r\n var mmkv = MMKV.defaultMMKV();\r\n\r\n mmkv.removeValue('bool');\r\n print('contains \"bool\": ${mmkv.containsKey('bool')}');\r\n\r\n mmkv.removeValues(['int32', 'int']);\r\n print('all keys: ${mmkv.allKeys}');\r\n ```\r\n\r\n* If different modules/logic need **isolated storage**, you can also create your own MMKV instance separately:\r\n\r\n ```dart\r\n var mmkv = MMKV(\"test\");\r\n mmkv.encodeBool('bool', true);\r\n print('bool = ${mmkv.decodeBool('bool')}');\r\n ```\r\n\r\n* If **multi-process accessing** is needed，you can set `MMKV.MULTI_PROCESS_MODE` on MMKV initialization:\r\n\r\n ```dart\r\n var mmkv = MMKV(\"test-multi-process\", mode: MMKVMode.MULTI_PROCESS_MODE);\r\n mmkv.encodeBool('bool', true);\r\n print('bool = ${mmkv.decodeBool('bool')}');\r\n ```\r\n\r\n### Supported Types\r\n* Primitive Types:\r\n - `bool, int, double`\r\n\r\n* Classes & Collections:\r\n - `String, List, MMBuffer`\r\n\r\n### Log\r\n\r\n* By default, MMKV prints log to logcat/console, which is not convenient for diagnosing online issues. \r\nYou can setup MMKV **log redirecting** on App startup on the **native** interface of MMKV. \r\nCheckout how to do it on [Android](https://github.com/Tencent/MMKV/wiki/android_advance#log) / [iOS](https://github.com/Tencent/MMKV/wiki/ios_advance#log).\r\nDue to the current limitation of Flutter runtime, we can't redirect log on the Flutter side.\r\n\r\n* You can turn off MMKV's logging once and for all on initialization (which we strongly disrecommend). \r\n\r\n ```dart\r\n final rootDir = await MMKV.initialize(logLevel: MMKVLogLevel.None);\r\n ```\r\n### Encryption\r\n* By default MMKV stores all key-values in plain text on file, relying on Android's/iOS's sandbox to make sure the file is encrypted. Should you worry about information leaking, you can choose to encrypt MMKV.\r\n\r\n ```dart\r\n final encryptKey = 'MyEncryptKey';\r\n var mmkv = MMKV(\"test-encryption\", cryptKey: encryptKey);\r\n ```\r\n\r\n* You can change the encryption key later as you like. You can also change an existing MMKV instance from encrypted to unencrypted, or vice versa.\r\n\r\n ```dart\r\n // an unencrypted MMKV instance\r\n var mmkv = MMKV(\"test-encryption\");\r\n\r\n // change from unencrypted to encrypted with AES-128 key length\r\n mmkv.reKey(\"Key_seq_1\");\r\n\r\n // change encryption key with AES-256 key length\r\n mmkv.reKey(\"Key_Seq_Very_Looooooooong\", aes256: true);\r\n\r\n // change from encrypted to unencrypted\r\n kmmkv.reKey(null);\r\n ```\r\n \r\n### Customize location\r\n* By default, MMKV stores file inside `$(FilesDir)/mmkv/`. You can customize MMKV's **root directory** on App startup:\r\n\r\n ```dart\r\n final dir = await getApplicationSupportDirectory();\r\n final rootDir = await MMKV.initialize(dir, rootDir: dir.path + '/mmkv_2');\r\n print('MMKV for flutter with rootDir = $rootDir');\r\n ```\r\n\r\n* You can even customize any MMKV instance's location:\r\n\r\n ```dart\r\n final dir = await getApplicationSupportDirectory();\r\n var mmkv = MMKV('testCustomDir', rootDir: dir.path + '/mmkv_3');\r\n ```\r\n **Note:** It's recommended to store MMKV files **inside** your App's sandbox path. **DO NOT** store them on external storage(aka SD card). If you have to do it, you should follow Android's [scoped storage](https://developer.android.com/preview/privacy/storage) enforcement.\r\n\r\n### Additional docs\r\nFor additional documents, checkout the [wiki](https://github.com/Tencent/MMKV/wiki/flutter_setup).\r\n\r\n## License\r\nMMKV is published under the BSD 3-Clause license.
