I am trying to use two different Map Fragment in two different Fragment Activities. And as per the SupportMapFragment design, I am keeping the map key in the META TAG of the appilcation properties in Manifest file. However my Map view is not clearing, it is showing same map with old points in the second Fragment eventhough I am calling "getMap().clear()". Please suggest
This is working fine untill and unless I dont use new MapFragment in a separate Activity, If I use new Mapfragment, it is taking the same map view, so the map view is not clearing.
Code :
MAP FRAGMENT
public class DisplayMapFragment extends SupportMapFragment implements OnMarkerClickListener,OnInfoWindowClickListener {
View mMapViewContainer;
MapView mMapView;
