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

        switch (v.getId()) {
            case R.id.sign_in_button:
                signIn();
                break;
            case R.id.sign_out_button:
                signOut();
                break;
            case R.id.disconnect_button:
                revokeAccess();
                break;
        }
    }
}

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();
}
