So, getMapAsync should be used as it waits till the map is properly initialized and provides the Map instance via a callback.

public class MapActivity extends Activity implements OnMapReadyCallback {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map_activity);

        MapFragment mapFrag = (MapFragment) getFragmentManager()
                .findFragmentById(R.id.map);
        mapFrag.getMapAsync(this);
    }

    @Override
    public void onMapReady(GoogleMap map) {
        // Place your logic here
        map.setIndoorEnabled(true);
        map.setBuildingsEnabled(true);
        map.getUiSettings().setZoomControlsEnabled(false);
    }
}

getMap() is deprecated

public void getMapAsync (OnMapReadyCallback callback)

Sets a callback object which will be triggered when the GoogleMap instance is ready to be used.

Note that:

This method must be called from the main thread.
The callback will be executed in the main thread.
In the case where Google Play services is not installed on the user's device, the callback will not be triggered until the user installs it.
In the rare case where the GoogleMap is destroyed immediately after creation, the callback is not triggered.
The GoogleMap object provided by the callback is non-null.
