Android, google maps fragment und viewpager - Fehler beim Aufblasen der Klassenfragmente

Question

ich versuche google maps v2 innerhalb von viewpager (fragmentpager) in einem fragment zu verwenden. Es funktioniert gut, wenn ich zum vierten Fragment wische (Pager sehen), aber wenn ich zurück zum ersten Fragment gehe und dann zurück zum vierten - mit der Karte - stirbt meine App.

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; 
} 

} 

Layout:

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent"

Ich habe gesehen, dass es viele Fäden mit einem ähnlichen Problem, aber keine Lösung: -/

Perhaps kann jemand diesmal helfen.

---------- EDIT ----- fand ich die Lösung :-)

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 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

Das ist für mich gearbeitet.

@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(); 
    } 
}
