Android PluginManager

dynamic load uninstalled apk

PluginManager is used to manage android applications like eclipse plugins. you can start an activity from an uninstalled apk placed in sdcard,just like it has installed or registed in the application's AndroidManifest.xml.

• a normal apk is regard as plug-in
• start activity from plug-in
• start other Activity from plug activity
• plug activity with theme
• plug with custom Application
• plug with .so
• support android2.x

it's easy to use:

• declare permission in your AndroidManifest.xml:

  <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />

  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

• regist an activity

  <activity android:name="androidx.pluginmgr.DynamicActivity" />

• init PluginMgr in your application

  @Override
  public void onCreate(){
     PluginManager.init(this);
     //...
  }

• load plugin from plug apk:

  PluginManager mgr = PluginManager.getSingleton();
  File myPlug = new File("/mnt/sdcard/Download/myplug.apk");
  PlugInfo plug = pluginMgr.loadPlugin(myPlug).iterator().next();

• start activity: mgr.startMainActivity(context, plug);

• Plugin verify feature

    PluginManager.getSingleton().setPluginOverdueVerifier(new PluginOverdueVerifier() {
            @Override
            public boolean isOverdue(File originPluginFile, File targetExistFile) {
                //check If the plugin has expired
                return true;
            }
        });

• Use custom selector

    PluginManager.getSingleton().setActivitySelector(new DynamicActivitySelector() {
            @Override
            public Class<? extends Activity> selectDynamicActivity(ActivityInfo pluginActivityInfo) {
  
                return YourProxyActivity.class;
            }
        });

• 破壳系统 - 取得存在于宿主中的对象

    Context hostContext = (Context) getSystemService("GetHostContext");
    String pluginPackageName = (String) getSystemService("GetPluginPkgName");
    PackageInfo pluginPackageInfo = (PackageInfo) getSystemService("GetPluginPkgInfo");
    //...
    //破壳系统支持的操作详见 androidx/pluginmgr/Globals.java
