Android Java:

public class LocationDetail extends Fragment {

private SupportMapFragment mMapFragment;
private GoogleMap map;
private EventAdapter listAdapter ;

protected MainActivity activity;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View vw = inflater.inflate(R.layout.map, container, false);

    try {
        MapsInitializer.initialize(getActivity());
    } catch (GooglePlayServicesNotAvailableException e) {
        // TODO handle this situation
    }

    map = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map_container)).getMap();
    map.setMyLocationEnabled(true);


    map.addMarker(new MarkerOptions()
    .position(new LatLng(48.397141, 9.98787)).title(" Theatro Club Ulm"));

    map.moveCamera( CameraUpdateFactory.newLatLngZoom(new LatLng(48.397141, 9.98787) , 14.0f) );

    return vw;
}

}

    super.onDestroyView();

    try {
        Fragment fragment = (getFragmentManager().findFragmentById(R.id.map_container));  
        FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
        ft.remove(fragment);
        ft.commit();
    } catch (Exception e) {
        e.printStackTrace();

Answer 1

public void onDestroyView() {
super.onDestroyView();

try {
    Fragment fragment = (getFragmentManager().findFragmentById(R.id.map_container));  
    FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
    ft.remove(fragment);
    ft.commit();
} catch (Exception e) {
    e.printStackTrace();
}

}

Answer 2

This worked for me.

@Override
public void onDestroyView() {
    // TODO Auto-generated method stub
    super.onDestroyView();
    try 
    {
        FragmentTransaction ft = getChildFragmentManager().beginTransaction();
        ft.remove(mapFragment);
        ft.commitAllowingStateLoss();
    } catch (Exception e) {
        e.printStackTrace();
    }
}
