onMapReady not calling even though the map display without any error

Question

I'm trying to display a simple map using Google map API v2 in an Android application. I'm following the Map API Documentation instructions. But I think the onMapReady is not calling for some reason. I'm using google-play-services_lib version 6587000. My phone has google-play-services_lib verion 6587038, I believe.

Google map is working with initial controls. Can someone help me to correct this error?

public class MapDisplay extends FragmentActivity implements OnMapReadyCallback {  private GoogleMap mMap; private Location mCurrentLocation; private MarkerOptions mMarkerOptions ;     private MapFragment mMapFragment;      @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.location_map);      /** not needed             mMapFragment = MapFragment.newInstance();             FragmentTransaction fragmentTransaction =                     getFragmentManag  er().beginTransaction();             fragmentTransaction.add(R.id.map, mMapFragment);             fragmentTransaction.commit();*/      /**corrected code*/             MapFragment mapFragment = (MapFragment) getFragmentManager()                     .findFragmentById(R.id.map);                 mapFragment.getMapAsync(this);  }   @Override public void onMapReady(GoogleMap map) {      toast("Map ready");     Log.d("--***** MAP  ","::Map ready");      LatLng sydney = new LatLng(-33.867, 151.206);      map.setMyLocationEnabled(true);     map.moveCamera(CameraUpdateFactory.newLatLngZoom(sydney, 13));      map.addMarker(new MarkerOptions()             .title("Sydney")             .snippet("The most populous city in Australia.")             .position(sydney));       }   private void toast(String text){         Toast toast = Toast.makeText(this, text, Toast.LENGTH_SHORT);         toast.show();      }     } 

location_map.xml file

<?xml version="1.0" encoding="utf-8"?> <fragment xmlns:android="http://schemas.android.com/apk/res/android"     android:name="com.google.android.gms.maps.MapFragment"     android:id="@+id/map"     android:layout_width="match_parent"     android:layout_height="match_parent"/> 

Answer 1

AFAIK, onMapReady() is triggered by a call to getMapAsync() on your MapFragment, and I do not see where you are calling that.

Answer 2

To call OnMapReady(GoogleMap map), append the following to your onCreate(...) method :

MapFragment mapFragment = (MapFragment)      getFragmentManager().findFragmentById(R.id.map); 

then, add:

// This calls OnMapReady(..). (Asynchronously) mapFragment.getMapAsync(MapDisplay.this);
