谷歌API客户端在某个时候onConnected NULL [英] Google Api Client sometime NULL in onConnected

问题描述

我implmenet GoogleApi客户波纹管：

I implmenet GoogleApi client as bellow:

 mGoogleApiClient = new GoogleApiClient.Builder(this)
                .enableAutoManage(this, 0 /* clientId */, this)
                .addApi(LocationServices.API)
                .addApi(Places.GEO_DATA_API)
                .addConnectionCallbacks(this)
                .build();

但在onConnected方法我检查mGoogleApiClient => null值。
在这种情况下，我尝试重新建立googleApiClient但我得到的错误：

But in onConnected method I check mGoogleApiClient => value null. In this case I try to re-build googleApiClient but I get error:

  java.lang.IllegalStateException: Already managing a GoogleApiClient with id 0

请帮助我了解为什么mGoogleApiClient一段时间NU​​LL althought它的连接：|。 （注，我查了所有的源$ C ​​$ C，我从未GoogleApiClient为NULL）。

Please help me understand why mGoogleApiClient some time NULL althought it's connected :|. (Notes. I checked all source code, I never set GoogleApiClient to NULL).

谢谢！

推荐答案

我有同样的问题。我所做的，解决它删除 .enableAutoManage（这一点，0 / * *的clientId /，这一点），因为它只是不正确地从我假定工作。然后，覆盖您的活动这些方法：

I had the same problem. All I did to solve it is remove .enableAutoManage(this, 0 /* clientId */, this) because it just doesn't work properly from what I assumed. Then, override these methods in your activity:

@Override
protected void onStart() {
    super.onStart();
    if (mGoogleApiClient != null)
        mGoogleApiClient.connect();
}

@Override
protected void onStop() {
    if (mGoogleApiClient != null && mGoogleApiClient.isConnected()) {
        mGoogleApiClient.disconnect();
    }
    super.onStop();
}

从技术上讲，这就是 .enableAutoManage（这一点，0 / * *的clientId /，这一点）是应该做的，但现在，一切正常，因为它应该。

Technically, that is what .enableAutoManage(this, 0 /* clientId */, this) was supposed to do, except that now, everything works as it should.
