Everything works right the first time, if you launch a second time you see this error:

As I understand it, the problem is in these lines:
mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
.enableAutoManage(getActivity()/* FragmentActivity */, this /* OnConnectionFailedListener */)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
I tried explicitly passing an id of 0:
.enableAutoManage(getActivity() /* FragmentActivity */, 0, this /* OnConnectionFailedListener */)
but that still didn’t work.
What am I missing?

Answer
You should call stopAutoManage() in the onPause() method of your Fragment:
@Override
public void onPause() {
super.onPause();
mGoogleClient.stopAutoManage(getActivity());
mGoogleClient.disconnect();
}
