已经使用id 0pipe理GoogleApiClient在FRAGMENT中
一切正常，如果你第二次去这个片段接收错误。 我试图把null，如果查看，但不能改变任何东西。 码：

据我了解，问题来自这里
mGoogleApiClient = new GoogleApiClient.Builder(getActivity()) .enableAutoManage(getActivity()/* FragmentActivity */, this /* OnConnectionFailedListener */) .addApi(Auth.GOOGLE_SIGN_IN_API, gso) .build();
我试图把0，但仍然无法正常工作。
.enableAutoManage(getActivity(), 0 /* FragmentActivity */, this /* OnConnectionFailedListener */)
我能做什么 ？ 谢谢。
您可以尝试在onPuase()或片段的任何其他生命周期事件中调用stopAutoManage()
@Override public void onPause() { super.onPause(); mGoogleClient.stopAutoManage(getActivity()); mGoogleClient.disconnect(); }
您也应该在片段的onPause（）方法中添加对stopAutoManage（）的调用：
@Override public void onPause() { super.onPause(); mGoogleApiClient.stopAutoManage(getActivity()); mGoogleApiClient.disconnect(); }
避免进一步的问题
@Override public void onStop() { super.onStop(); if (mGoogleApiClient != null && mGoogleApiClient.isConnected()) { mGoogleApiClient.stopAutoManage((Activity) context); mGoogleApiClient.disconnect(); } }
enableAutoManage官方文档说：
在任何时候，每个ID只允许一个自动pipe理的客户端。 要重用一个id，你必须先在前一个客户端上调用stopAutoManage（FragmentActivity）。
你的代码使用enableAutoManage的版本，没有一个clientId参数，所以它默认为0.下面我解释为什么你将有多个自动pipe理的客户端clientId 0，这是上面的文档是警告。
在您的Login Fragment附加到FragmentActivity后，它会告知该活动开始pipe理一个新的GoogleApiClient实例。 但是，如果FragmentActivity已经在pipe理另一个GoogleApiClient实例呢？ 那是当你得到错误。
有几个可能的情况，可能导致这个多谷歌API每个FragmentActivity情况。
- 除了创buildGoogleApiClient的Login之外，FragmentActivity还有另外一个片段，并且要求FragmentActivity来pipe理它。
- FragmentActivity本身创build一个GoogleApiClient并在Login Fragment附加到FragmentActivity之前开始pipe理它。
-
也许你在FragmentTransaction中添加Login Fragment，然后调用addToBackStack。 然后，用户轻点，然后以某种方式login片段重新连接。 在这种情况下，重要的Login Activity方法调用是onCreateView – > onDestroyView – > onCreateView，如下所示：
这是有问题的，因为第二次调用Login.onCreateView试图让FragmentActivitypipe理第二个GoogleApiClient。
如果我是你，我会认真考虑在活动中创buildGoogleApiClient，而不是在任何片段中。 然后，您可以在Activity中执行需要GoogleApiClient的工作，或者在从Activity获取GoogleApiClient之后继续在Login Fragment中执行此操作，如下所示：
private GoogleApiClient googleApiClient; @Override void onAttach(Activity activity) { super.onAttach(activity); googleApiClient = activity.getGoogleApiClient(); } @Override void onDetach() { super.onDetach(); googleApiClient = null; }
我遇到了类似的问题，因为我已经在属于同一个Activity的两个不同片段上放置了loginbutton。
所以为了解决这个问题，我在创buildGoogleApiClient的新对象时分配了不同的id来启用 AutoManage。
例如，在片段1中，在创buildGoogleApiClient对象时， 将其赋值为0 ：
mGoogleApiClient = new GoogleApiClient.Builder(getActivity()) .enableAutoManage(getActivity(), 0, this /* OnConnectionFailedListener */) .addApi(Auth.GOOGLE_SIGN_IN_API, gso) .build();
在Fragment 2中，在创buildGoogleApiClient对象时， 将 id 赋值为1，如下所示：
mGoogleApiClient = new GoogleApiClient.Builder(getActivity()) .enableAutoManage(getActivity(), 1, this /* OnConnectionFailedListener */) .addApi(Auth.GOOGLE_SIGN_IN_API, gso) .build();
尝试从您的活动中使用您的mGoogleApiClient 。 如果您已经在您的活动中声明了GoogleApiClient ，那么您无法在您的片段上重新声明。 而是从片段中重新使用该活动中的variables
mGoogleApiClientInFragment = ((Youractivityclass)getActivity()).mGoogleApiClient;
用您的片段的活动replaceYouractivityClass ，并确保将您的活动中的mGoogleApiClient字段设置为公开
