if you need zooming effect very close 
LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
  
/*   CameraPosition cameraPosition = new CameraPosition.Builder()
      .target(latLng).zoom(19f).tilt(70).build();
   googleMap.setMyLocationEnabled(true);
      googleMap.animateCamera(CameraUpdateFactory
              .newCameraPosition(cameraPosition));*/
