Minimum Android version supported is Honeycomb (API level 11). For a version compatible with Unity 4 or with older Android devices, please checkout changeset tagged `1.0`.\nThe C# API of the plugin is available in `IGooglePlayObbDownloader` interface. Use `GooglePlayObbDownloadManager.GetGooglePlayObbDownloader()` to obtain an instance.\n\n0.\tAdd the plugin to your project. You need the AAR and the C# scripts (`Assets/Plugins/Android/unityOBBDownloader.aar`, `Assets/Scripts/GooglePlayDownloader.cs` and `Assets/Scripts/GooglePlayDownloaderImpl.cs`)\n1.\tIn your script, don't forget to set `PublicKey` to your own value. You'll see a message logged and probably a crash if you skip this step\n2.\tChange the Bundle Identifier / Version Code so it matches the application already available on Google Play (that has .obb files attached)\n3.\tBuild and Run on your Android device\n\nFor a script sample, please refer to `Assets/Scripts/DownloadObbExample.cs`.\n\n## How to Build\nRun `gradlew assemble` from src/UnityAndroidPermissions/\n\n## License\nCopyright (C) 2016-2017 Yury Habets\n\nLicensed under the Apache License, Version 2.0 (the \"License\");\nyou may not use this file except in compliance with the License.\nYou may obtain a copy of the License at\n\n http://www.apache.org/licenses/LICENSE-2.0\n\nUnless required by applicable law or agreed to in writing, software\ndistributed under the License is distributed on an \"AS IS\" BASIS,\nWITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\nSee the License for the specific language governing permissions and\nlimitations under the License.\n\n## See also\nFor more information on using .obb files in Unity, please refer to http://docs.unity3d.com/Manual/android-OBBsupport.html and http://developer.android.com/guide/market/expansion-files.html\n\nFor more information on Unity Android plugins, please refer to http://docs.unity3d.com/Manual/PluginsForAndroid.html\n" }, { "path": "src/unityOBBDownloader/build.gradle", "content": "apply plugin: 'com.android.library'\n\nbuildscript {\n\trepositories {\n\t\tjcenter()\n\t\tgoogle()\n\t}\n\n\tdependencies {\n\t\tclasspath 'com.android.tools.build:gradle:3.0.1'\n\t}\n} \n\nandroid {\n compileSdkVersion 26\n buildToolsVersion \"26.0.2\"\n\n defaultConfig {\n minSdkVersion 11\n targetSdkVersion 26\n }\n\n buildTypes {\n release {\n minifyEnabled true\n proguardFiles 'proguard.cfg'\n }\n }\n}\n" }, { "path": "src/unityOBBDownloader/gradle/wrapper/gradle-wrapper.properties", "content": "distributionBase=GRADLE_USER_HOME\ndistributionPath=wrapper/dists\nzipStoreBase=GRADLE_USER_HOME\nzipStorePath=wrapper/dists\ndistributionUrl=https\\://services.gradle.org/distributions/gradle-4.2.1-bin.zip\n" }, { "path": "src/unityOBBDownloader/gradlew", "content": "#!/usr/bin/env sh\n\n##############################################################################\n##\n## Gradle start up script for UN*X\n##\n##############################################################################\n\n# Attempt to set APP_HOME\n# Resolve links: $0 may be a link\nPRG=\"$0\"\n# Need this for relative symlinks.\nwhile [ -h \"$PRG\" ] ; do\n ls=`ls -ld \"$PRG\"`\n link=`expr \"$ls\" : '.*-> \\(.*\\)$'`\n if expr \"$link\" : '/.*' > /dev/null; then\n PRG=\"$link\"\n else\n PRG=`dirname \"$PRG\"`\"/$link\"\n fi\ndone\nSAVED=\"`pwd`\"\ncd \"`dirname \\\"$PRG\\\"`/\" >/dev/null\nAPP_HOME=\"`pwd -P`\"\ncd \"$SAVED\" >/dev/null\n\nAPP_NAME=\"Gradle\"\nAPP_BASE_NAME=`basename \"$0\"`\n\n# Add default JVM options here.

The IPC is implemented using an Android Messenger and a service Binder. The connect method\n * should be called whenever the client wants to bind to the service.
