当使用`FusedLocationApi`时，android在`LocationServices.API`和`Auth.GOOGLE_SIGN_IN_API`之间发生冲突

Question

I have code setGoogleSignInAccount like this

mGoogleApiClient = new GoogleApiClient.Builder(this)
                .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();

and i have code for get location using FusedLocationApi like this

Location mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
                            mGoogleApiClient);

and it's work but my question is now when i click logout error because .addApi(LocationServices.API) when i changes to .addApi(Auth.GOOGLE_SIGN_IN_API, gso) the logout is success but now the FusedLocationApi is error

and this logcat when FusedLocationApi error

Answer 1

when i changes to .addApi(Auth.GOOGLE_SIGN_IN_API, gso) the logout is success

Don't change. Add.

mGoogleApiClient = new GoogleApiClient.Builder(this)
                .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
                // Add more APIs, as needed
                .build();
