Текущее местоположение с android

Question

Я хочу добавить карту google с текущим местоположением. Как я могу это сделать? Я нашел этот код, но место статично. Как я могу это исправить?

public class MapFragment extends Fragment implements OnMapReadyCallback { 
    SupportMapFragment mSupportMapFragment; 
    private GoogleMap mMap; 
    int ZOOM_LEVEL=15; 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     View mTrackView = inflater.inflate(R.layout.fragment_map, container, false); 
     mSupportMapFragment = SupportMapFragment.newInstance(); 
     FragmentTransaction fragmentTransaction = getChildFragmentManager().beginTransaction(); 
     fragmentTransaction.add(R.id.mapwhere, mSupportMapFragment); 
     fragmentTransaction.commit(); 
     return mTrackView; 
    } 
    @Override 
    public void onMapReady(GoogleMap map) { 
     //googleMap = mMap; 
     setUpMapIfNeeded(); 
    } 
    public void onStart() { 
     // TODO Auto-generated method stub 
     super.onStart(); 
     if(mSupportMapFragment!=null){ 
      googleMap = mSupportMapFragment.getMap(); 
      if(googleMap!=null){ 
       googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL); 
       googleMap.getUiSettings().setMyLocationButtonEnabled(false); 
       googleMap.setMyLocationEnabled(false); 
       CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(
         new LatLng(12.12122, 
           17.22323), ZOOM_LEVEL); 
       googleMap.animateCamera(cameraUpdate); 
      } 
     } 
    } 
}
