坑 android.content.Context cn.bmob.v3.BmobWrapper.getAppalicationContext()

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Bmob.initialize(this, Bmob_AppId);    //都要进行初始化
        // 初始化View
        initView();
        initListener();

    }

@Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Bmob.initialize(this, Bmob_AppId); //都要进行初始化

}
