Android Wear應用程式java.lang.OutOfMemoryError：無法分配

Question

我有一個問題。 我想為我的Android Wear設備制作一個Android應用。 我想獲取當前位置的緯度和經度。 但是當我運行應用程序時，出現此錯誤：

這是我的代碼：

        @Override
        public void onLayoutInflated(WatchViewStub stub) {


            onClickInfoButtonListener();
        }
    });
}

    btSetHuidigeLocatie.setOnClickListener(
            new View.OnClickListener(){
