Fragment Wsparcie Mapsforge

Question

Zdaję sobie sprawę, że istnieje jakiś patch do fragmentów dotyczących Mapsforge tutaj: https://code.google.com/p/mapsforge/issues/detail?id=177 .Jednak nie jestem do końca pewien, jak go używać.

To właśnie zostały wdrożone do tej pory:

public class TOfflineMapViewFragment extends SherlockFragment{ 

    MapView myOpenMapView; 
    //other codes here... 

    public View onCreateView(LayoutInflater inflator, ViewGroup container, Bundle savedInstanceState) { 

      view = inflator.inflate(R.layout.offline_map_activity, container, false); 

      myOpenMapView = (MapView) view.findViewById(R.id.openmapview); 
      myOpenMapView.setMapFile(new File(Environment.getExternalStorageDirectory().toString() + 
      "/offlineMap/singapore.map"); 

      return view; 
    } 

} 

To jest mój plik xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" > 
    <org.mapsforge.android.maps.MapView 
     android:id="@+id/openmapview" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent"/> 
</LinearLayout> 

Dostaję taki błąd:

Co jest źle z tym?

Answer 1

dodanie

AndroidGraphicFactory.createInstance(getActivity().getApplication()); 

w zastąpionej onCreate() pracował dla mnie
