Patch for cocos android

  • Dynamic load game
// Load game by AssetManager.addAssetPath method
public static boolean addAssetPath(Activity activity, String path) {
        try {
            AssetManager assetManager = activity.getAssets();
            Object result = AssetManager.class.getDeclaredMethod("addAssetPath", String.class).invoke(
                    assetManager, path);
            Log.i(TAG, "addAssetPath result:" + result.toString());

            int resultInt = (int) result;
            if (resultInt != 0) {
                return true;
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return false;
}
  • Disable check task root
protected final static boolean IS_CHECK_ROOT = false;
if (IS_CHECK_ROOT && !isTaskRoot()) {
        // Android launched another instance of the root activity into an existing task
        //  so just quietly finish and go away, dropping the user back into the activity
        //  at the top of the stack (ie: the last state of this task)
        // Don't need to finish it again since it's finished in super.onCreate .
        return;
}
  • Disable decrypt js
Modify AppDelegate.cpp, need dynamic set decrypt key, or set the default key for all game.
// jsb_set_xxtea_key("3b4139a4-456c-42");
