   super.onCreate(savedInstanceState);
   gameHelper = new GameHelper(this, GameHelper.CLIENT_GAMES);
   gameHelper.enableDebugLog(false);
   GameHelperListener gameHelperListener = new GameHelper.GameHelperListener() {
        @Override
        public void onSignInSucceeded() {
        }

        @Override
        public void …
