从代码中删除图片中的选定行

Answer 2

我解决了上述问题，实际上应用程序崩溃了因为我没有将谷歌客户端连接到我的Homepageactvity.So一旦我将谷歌客户端连接到我的Homepageactvity，那么我可以从我的注销应用程序。 首先，我将下面的代码放入我的On create method

 GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestScopes(new Scope(Scopes.DRIVE_APPFOLDER))
            .requestEmail()
            .build();
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();

之后我调用了googlesignout的方法。它现在工作正常
