google maps - Android MapView does not load unless you touch on the mapview

Question

I have added a mapview in my android application.I have used correct settings in the manifest and now i'm facing a problem. When i go to the place where i have my map,it displays only the canvas but not the map. If i touch on it only it starts loading. Even then it does not fully load.it loads only to a certain level.if i keep touching the screen it continuously loads. But even then i cannot zoom in or out OR cant even move the map. Is there a solution for this? Have i done something wrong?

My Code

            MapView mapView;
            GoogleMap map;





             mapView = (MapView)view.findViewById(R.id.map);
             Bundle savedInstanceState = null;
            mapView.onCreate(savedInstanceState);

                // Gets to GoogleMap from the MapView and does initialization stuff
                map = mapView.getMap();
                map.getUiSettings().setMyLocationButtonEnabled(false);
                map.setMyLocationEnabled(true);

                MapsInitializer.initialize(activity);

                double lat;
                double lon;

                lat = Double.parseDouble(theaterDetail.getLatitude());
                lon = Double.parseDouble(theaterDetail.getLongitude());

                // Updates the location and zoom of the MapView
                map.addMarker(new MarkerOptions().position(
                        new LatLng(lat, lon)).title(theaterDetail.getAddress()));

                final LatLng THEATER_POSITION = new LatLng(lat, lon);

                CameraPosition cameraPosition = new CameraPosition.Builder()
                        .target(THEATER_POSITION) // Sets the center of the map to
                                                    // THEATER_POSITION
                        .zoom(10) // Sets the zoom
                        .bearing(360) // Sets the orientation of the camera to east
                        .tilt(30) // Sets the tilt of the camera to 30 degrees
                        .build(); // Creates a CameraPosition from the builder
                        map.animateCamera(CameraUpdateFactory
                        .newCameraPosition(cameraPosition));

Answer 1

Though this is an old question, I am providing here what worked for me. The reason that this solution works is that it overrides the onResume() handler. If you are using a mapView, you need to call mapView.onResume() from the onResume() handler. Example:

@Override
public void onResume() {
    mMapView.onResume();
    super.onResume();
}
