NulPointerException em maps.y.p.onResume (Unknown Source) na implementação de fragmentos para OSMDroid

No momento, estou tentando transferir minha atividade de mapa do OSMDroid para fragmentos. Parece que tudo foi configurado corretamente, mas estou recebendo este NullPointerException estranho que não tenho certeza da solução.

Aqui está minha parte dos meus códigos para a classe de fragmentos:

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

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


    myOpenMapView = (MapView) view.findViewById(R.id.openmapview);

    mResourceProxy = new DefaultResourceProxyImpl(getSherlockActivity().getApplicationContext());
    myOpenMapView.getTileProvider().clearTileCache();

    File aFile = new File(Environment.getExternalStorageDirectory().toString() + 
            "/test/offlineMap/" + tID + ".zip");
    IArchiveFile[] myArchives = new IArchiveFile[1];
    myArchives[0] = ArchiveFileFactory.getArchiveFile(aFile);
    MyTileSource myTiles = new MyTileSource( "" + tID, null, 12, 12, 256, ".png");
    MapTileModuleProviderBase[] myProviders = new MapTileModuleProviderBase[2];
    myProviders[0] = new MapTileFileArchiveProvider(new SimpleRegisterReceiver(getSherlockActivity().getApplicationContext()), 
            myTiles, myArchives);
    myProviders[1] =  new MapTileDownloader(TileSourceFactory.MAPNIK);
    MapTileProviderArray MyTileProvider = new MapTileProviderArray(myTiles,null, myProviders);
    TilesOverlay MyTilesOverlay = new TilesOverlay(MyTileProvider, getSherlockActivity().getApplicationContext());
    //codes continue...


    return view;
}

Deixe-me saber se mais códigos precisam ser mostrados. Obrigado!
