Google登录＆＃34;首次登录时检查＆＃34;和＆＃34;退出＆＃34; android应用程序中的问题

标签： android sharedpreferences logout google-plus-signin

我正在创建一个Android应用程序，当用户安装应用程序时，他/她需要使用Google帐户登录，登录成功后，他/她将被重定向到仪表板页面。如果他/她关闭应用程序并再次打开它并且如果他们已经登录，那么应该显示仪表板活动。另外，我的仪表板活动中有一个抽屉布局，其中有一个＆＃34;退出＆＃34;用户可以从中注销并再次打开登录活动的按钮。

  • 我正在使用SharedPreference检查android中的首次登录

    以下是我所面临的问题

  • 应用程序打开仪表板活动而不要求登录。

  • 当＆＃34;退出＆＃34;从仪表板活动中的抽屉布局中单击，一秒钟它将进入登录活动，但会再次自动登录。简而言之＆＃34;退出＆＃34;它不起作用，它让我登录。

以下是用户首次打开应用时的屏幕截图。它没有要求我登录。 It doesn't ask for log-in

但是当我特意点击退出时，会显示登录活动， enter image description here

下面我已经显示了屏幕截图或结果，每次我尝试注销但它再次登录我。任何输入将不胜感激。 enter image description here

点击退出时试试方法

从Google退出 

private void signOutFromGplus(){
        if (mGoogleApiClient.isConnected(){
            Plus.AccountApi.clearDefaultAccount(mGoogleApiClient);
            mGoogleApiClient.disconnect();
            mGoogleApiClient.connect();
        }
}
