googleApiClient.connect (); не подключается

Question

Я учусь использовать Android Studio, но у меня есть проблема, которую я не вижу, чтобы решить, даже глядя на сообщения (так что я могу что-то упустить).

Я вызываю метод .connnect () моей переменной googleApiClient. Но, похоже, это не работает, поскольку я получаю это исключение:

java.lang.IllegalStateException: GoogleApiClient is not connected yet.

Я сделал «если», чтобы проверить, подключен ли googleApiClient, но он говорит, что это не так.

это метод, который у меня есть:

protected synchronized void buildGoogleApiClient()
    {
        googleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();

        googleApiClient.connect();

        if (googleApiClient.isConnected())
            Log.d("GoogleApiClient", "buildGoogleApiClient: is connected");
        else
            Log.d("GoogleApiClient", "buildGoogleApiClient: is not connected");
    }

это журнал, который я получаю:

Я вызываю buildGoogleEnabled () для метода onMapReady

@Override
public void onMapReady(GoogleMap googleMap) {
    Object transferData[] = new Object[2];
    GetNearbyPlacesData getNearbyPlacesData = new GetNearbyPlacesData();

    mMap = googleMap;
    //Ponemos el modo terreno
    mMap.setMapType(GoogleMap.MAP_TYPE_TERRAIN);

    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED)
    {
        buildGoogleApiClient();

        mMap.setMyLocationEnabled(true);
    }

    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);

    mMap.clear();
    String url = getUrl(latitide, longitude, "museum");
    transferData[0] = mMap;
    transferData[1] = url;

    getNearbyPlacesData.execute(transferData);
    Toast.makeText(this, "Searching for Nearby Museums...", Toast.LENGTH_SHORT).show();
    Toast.makeText(this, "Showing Nearby Museums...", Toast.LENGTH_SHORT).show();
}
