从Google+注销其他活动 [英] logout from Google+ from other activity
本文介绍了从Google+注销其他活动的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我最近实施了Google+ API。我设法成功认证并进入主要活动。我的问题是，我想在操作栏菜单中包含一个LogOut选项，当用户回来时，系统会提示他再次登录。
我阅读几个答案，但我无法实现它们。
您能否建议实施此解决方案的最佳方法并提出一个很好的示例？
谢谢，<因此，我设法解决了这个问题，我创建了下面的基类，并将它继承了所需的活动，我测试了它按预期工作。对于需要构建它的想法的任何人，您可以使用下面的代码。
在主要登录活动中，需要根据两点来更改flags状态点击事件。
如果您想从其他活动的G +帐户注销，请务必首先初始化GoogleApiClient，否则您将收到空对象引用异常。 / p>
希望能帮助别人......

I have recently implemented the Google+ API. I managed to succesfully authenticated and move forward to the main activity. My issue is that I would like to include a "LogOut" option in the action bar menu and when the user comes back he will be prompted to login again.
I read several answers however I wasnt able to implement them.
can you please suggest the best way to implement this solution and suggest a good example?
Thanks,
解决方案
So I manage to solve the issue, i created the below base class and just inherited it over the needed activities, I tested and it worked as expected. to anyone who needs an idea on how to build it you can use the below code.
Two points, on the main login activity you will need to change the flags state according to the on click events.
if you like to logout from G+ account on other activity, make sure to initilize the GoogleApiClient first otherwise you will get null object reference exception.
hope that will help someone...
