Я работаю с Google Maps. Я могу успешно создать и показать карту Google. Теперь я хочу добавитьCameraUpdate(latitude, longitude), Я гуглил и нашел какой-то исходник, но получаюNullPointerException.

Сообщение об ошибке LogCat:

java.lang.NullPointerException: CameraUpdateFactory is not initialized

Это мой источник. Что я делаю неправильно?

public class StradaContact extends Fragment {

public final static String TAG = StradaContact.class.getSimpleName();
private MapView mMapView;
private GoogleMap mMap;
private Bundle mBundle;
double longitude = 44.79299800000001, latitude = 41.709981;

public StradaContact() {

}

public static StradaContact newInstance() {
    return new StradaContact();
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.strada_contact, container,false);

    mMapView = (MapView) rootView.findViewById(R.id.pointMap);

    mMapView.onCreate(mBundle);
    setUpMapIfNeeded(rootView);

    return rootView;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mBundle = savedInstanceState;
}

private void setUpMapIfNeeded(View inflatedView) {
    if (mMap == null) {
        mMap = ((MapView) inflatedView.findViewById(R.id.pointMap)).getMap();
        if (mMap != null) {
            CameraUpdate center = CameraUpdateFactory.newLatLng(new LatLng(latitude, longitude));
            CameraUpdate zoom = CameraUpdateFactory.zoomTo(15);
            mMap.moveCamera(center);
            mMap.animateCamera(zoom);
        }
    }
}
