关于demo 本项目是动态so加载的核心流程，所以并不直接演示so的下载过程，需要demo使用者将test_so_package的三个demo so库放到指定的演示位置（模拟so已经下载好了，可对接自己使用的下载方式），本例子是放在目录 ``` data/data/com.example.sillyboy/files/dynamic_so ``` ![image](https://user-images.githubusercontent.com/65278264/235083927-1a23914d-44da-493f-88ab-1b3dfa99326d.png) ## 设计原理 文档请看这里：https://juejin.cn/post/7107958280097366030 ## 使用说明 ### 声明 注意：由于这是一个基础库，如果需要在正式项目中使用，还是需要继续封装或者优化的，这里只是动态加载so的实现，在实战中应当配合so版本管理，下载器等实际使用 ### 使用步骤 1. 如何删除本地的so库【可选】 ``` 方式1 packagingOptions下增加 exclude 'lib/arm64-v8a/xxx.so' exclude 'lib/armeabi-v7a/xxx.so' ``` ``` 方式2 复制以下task到app的build.gradle 如果需要删除so的过程中进行一些列的定制化操作，可参考如下task，见app目录例子 ext { deleteSoName = ["libnativecpptwo.so","libnativecpp.so"] } // 这个是初始化 -配置 -执行阶段中，配置阶段执行的任务之一，完成afterEvaluate就可以得到所有的tasks，从而可以在里面插入我们定制化的数据 task(dynamicSo) { }.doLast { println("dynamicSo insert!!!! ") //projectDir 在哪个project下面，projectDir就是哪个路径 print(getRootProject().findAll()) def file = new File("${projectDir}/build/intermediates/merged_native_libs/debug/out/lib") //默认删除所有的so库 if (file.exists()) { file.listFiles().each { if (it.isDirectory()) { it.listFiles().each { target -> print("file ${target.name}") def compareName = target.name deleteSoName.each { if (compareName.contains(it)) { target.delete() } } } } } } else { print("nil") } } afterEvaluate { print("dynamicSo task start") def customer = tasks.findByName("dynamicSo") def merge = tasks.findByName("mergeDebugNativeLibs") def strip = tasks.findByName("stripDebugDebugSymbols") if (merge != null || strip != null) { customer.mustRunAfter(merge) strip.dependsOn(customer) } } ``` 2. 初始化 通过initDynamicSoConfig 方法初始化，第一个参数是context，第二个参数是path，即下载完的so的path，第三个参数是一个回调，在调用动态so加载的时候会先回调，如果返回值为true，才会真正进入到so的加载逻辑，提供给使用者版本校验等一些列活动 ``` // 在合适的时候将自定义路径插入so检索路径 需要使用者自己负责在这个路径上有写入权限 DynamicSoLauncher.INSTANCE.initDynamicSoConfig(this, path, s -> { // 处理一些自定义逻辑 return true; }); ``` 3. 调用so加载【有两种使用姿势】 3.1 手动加载 在使用到某个so方法前，需要调用loadSoDynamically（代替System.loadLibrary方法），参数是so的名称或者一个File，该File位于初始化时传入的path之内即可 ``` DynamicSoLauncher.INSTANCE.loadSoDynamically(file) ``` 3.2 注解加载 在需要采取动态so加载的类上，添加@DynamicLoad注解即可，内部会采用字节码插桩的方式，会把类中所有的System.loadLibrary 替换为DynamicSoLauncher内部的so加载 ``` //@DynamicLoad public class MainActivity extends AppCompatActivity { ``` 注意，执行这个步骤需要发布当前的lib_sillyplugin插件 ![image](https://user-images.githubusercontent.com/65278264/235086729-fa92051d-4282-4ffe-9817-d04de2587711.png) 之后在需要的工程build.gradle引入即可，跟一般的插件引入方式一样 ``` apply plugin: 'com.plugins.core' ``` ps：这里其实已经可以实现了无痕替代，只是考虑到大多数可能只动态加载少数的so，才提供出来注解的方式去限定范围。 ## 项目层级介绍 * **app下是使用例子** * **lib_sillyboy 是dyso的封装实现** * **lib_sillyplugin 是dyso的插件，用于替换代码的System.loadLibrary,默认关闭了，可看代码注释打开** ## 环境准备 建议直接用最新的稳定版本Android Studio打开工程。目前项目已适配`Android Studio Arctic Fox | 2020.3.1` ### ## 后续todo * **maven发布** * **贡献者名单** ================================================ FILE: app/.gitignore ================================================ /build ================================================ FILE: app/build.gradle ================================================ apply plugin: 'com.android.application' apply plugin: 'kotlin-android' // 替换System.loadLibrary的插件 //apply plugin: 'com.plugins.core' android { compileSdkVersion 31 packagingOptions { exclude 'META-INF/DEPENDENCIES' exclude 'migrateToAndroidx/migration.xml' exclude 'META-INF/common.kotlin_module' } defaultConfig { applicationId "com.example.sillyboy" minSdkVersion 23 targetSdkVersion 29 versionCode 1 versionName "1.0" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' } } compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } kotlinOptions { jvmTarget = '1.8' } viewBinding { enabled = true } } ext { deleteSoName = ["libnative1.so","libnative2.so","libnative3.so"] } // 这个是初始化 -配置 -执行阶段中，配置阶段执行的任务之一，完成afterEvaluate就可以得到所有的tasks，从而可以在里面插入我们定制化的数据 task(dynamicSo) { }.doLast { println("dynamicSo insert!!!!
