you can do this using `getMapAsync` , and in `onMapReady` method you will get the map object.
public class YourMapActivity extends FragmentActivity implements OnMapReadyCallback {
@Override protected void onCreate(Bundle savedInstanceState) { // ...
((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMapAsync(this); }
@Override public void onMapReady(final GoogleMap googleMap) {
// you will get map object hare mGoogleMap = googleMap;
// now perform operations on that. } }

The `getMap` method is deprecated. You should use `getMapAsync`:
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
@Override protected void onCreate(Bundle savedInstanceState) { // ...
((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMapAsync(this); }
@Override public void onMapReady(final GoogleMap googleMap) { mGoogleMap = googleMap;
// Do something with your map } }
