Getting Error While Integrating MapFragments with OSMDroid

I am currently trying to transfer my OSMDroid Map Activity into Fragments. It seems that everything has been set correctly but I'm getting this weird NullPointerException which I'm unsure of solving.

Here are my part of my codes for the fragment class:

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( "https://myboxingheadgear.com/" + 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;

I'm kinda following this from various sources but it still doesn't work. Can anyone enlighten me what did I do wrong?

Do let me know if more of the codes need to be shown. Thanks!

return view;
