VirtualAPK is a powerful yet lightweight plugin framework for Android. It can dynamically load and run an APK file (we call it LoadedPlugin) seamlessly as an installed application. Developers can use any Class, Resources, Activity, Service, Receiver and Provider in LoadedPlugin as if they are registered in app's manifest file.

Add a dependency in build.gradle in root of host project as following.

dependencies {
    classpath 'com.didi.virtualapk:gradle:0.9.8.6'
}

Apply plugin in application module of build.gradle.

apply plugin: 'com.didi.virtualapk.host'

Compile VirtualAPK in application module of build.gradle.

compile 'com.didi.virtualapk:core:0.9.8'

Initialize PluginManager in YourApplication::attachBaseContext().

@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    PluginManager.getInstance(base).init();
}

Modify proguard rules to keep VirtualAPK related files.

-keep class com.didi.virtualapk.internal.VAInstrumentation { *; }
-keep class com.didi.virtualapk.internal.PluginContentResolver { *; }

-dontwarn com.didi.virtualapk.**
-dontwarn android.**
-keep class android.** { *; }

Finally, load an APK and have fun!

String pluginPath = Environment.getExternalStorageDirectory().getAbsolutePath().concat("/Test.apk");
File plugin = new File(pluginPath);
PluginManager.getInstance(base).loadPlugin(plugin);

// Given "com.didi.virtualapk.demo" is the package name of plugin APK, 
// and there is an activity called `MainActivity`.
Intent intent = new Intent();
intent.setClassName("com.didi.virtualapk.demo", "com.didi.virtualapk.demo.MainActivity");
startActivity(intent);

Add a dependency in build.gradle in root of plugin project as following.

dependencies {
    classpath 'com.didi.virtualapk:gradle:0.9.8.6'
}

Apply plugin in application module of build.gradle.

apply plugin: 'com.didi.virtualapk.plugin'

Config VirtualAPK. Remember to put following lines at the end of build.gradle.

virtualApk {
    packageId = 0x6f             // The package id of Resources.
    targetHost='source/host/app' // The path of application module in host project.
    applyHostMapping = true      // [Optional] Default value is true. 
}
