当我尝试从片段（Android 6+；）将应用程序转换为MyApplication时，java.lang.ClassCastException

我有一个片段，它扩展了android.app.fragment。在onCreateView中，在某些情况下，当我尝试将应用程序强制转换为应用程序的实现时，我有java.lang.ClassCastException

public class SketchFragment extends android.app.Fragment{
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View inflate = inflater.inflate(R.layout.layout, container, false);
        ButterKnife.bind(this,inflate);

        MyApplication application = (MyApplication)  getActivity().getApplicationContext();

        //Previously, I tried to
        //MyApplication application = (MyApplication) getActivity().getApplication()

        }
    }

事实上，我有这个错误

提前感谢

您对此进行过调查吗？你能找出原因吗？在我的服务类中，Android 6.0中的一些用户也遇到了同样的异常。Service.getApplication（）不再强制转换为。看起来像是android问题，但尚未解决或确认-
