help help..huu

Im having a problem here..seems there was no error in codes..but when I run it...and click button to view map consist routing the map..It appers to be close all of sudden..why is that? Please help me friends..

Im developing an app to read my current location and creating route to A position..

here are the codes:

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map);

    onNewIntent(getIntent());

    Drawable marker = getResources().getDrawable(R.drawable.marker);
    Drawable marked_places = getResources().getDrawable(R.drawable.feringgi_map);

    mymap = (MapView)findViewById(R.id.mymap);
    controller = mymap.getController();
    // extract MapView from layout
    mymap.getController().setZoom(15);
    mymap.setBuiltInZoomControls(true);
    mymap.setSatellite(false);

    // create an overlay that shows our current location
    myLocationOverlay = new MyLocationOverlay(this, mymap);

    // add this overlay to the MapView and refresh it
    mymap.getOverlays().add(myLocationOverlay); 
    mymap.postInvalidate();

    myLocationOverlay.runOnFirstFix(new Runnable() {

        @Override
        public void run() {
            controller.setZoom(10);
            controller.animateTo(myLocationOverlay.getMyLocation());                
        }
    });

    zoomToMyLocation();

   switch(selecteditem)
   {
   case 0:        switch(selectedsubitem){
            case 0://Place A       
                    locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
                  locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this);
                  Location location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                      if (location !=null) {
                      loc=location;
                  }
                  GeoPoint destination = getPoint(3.144341, 101.69541800000002);
                  new BackgroundTask(this, loc, destination).execute();
                break;              
}
}

 class BackgroundTask extends AsyncTask<Void, Void, Void> {

        private Location location;
        private GeoPoint dest;
        private Route route;
        private Activity activity;
        private ProgressDialog dialog;
        private RouteOverlay routeOverlay;

        public BackgroundTask(Activity activity, Location loc, GeoPoint dest) {
            location=loc; 
            this.dest=dest;
            this.activity=activity;
            dialog = new ProgressDialog(activity);
        }

        @Override
        protected void onPreExecute() {
            dialog.setCancelable(false);
            dialog.setTitle("Loading...");
            dialog.setMessage("Calculating Route...");
            dialog.setButton("Cancel", new DialogInterface.OnClickListener() {
                public void onClick(final DialogInterface dialog, final int id) {
                  cancel(true);
                  MyMap.this.finish();
                }});
            dialog.show();
        }

protected Void doInBackground(Void... params) {
                if(isNetworkAvailable())
                {
                    if(haveInternet())
                    {   try{
                            route = directions(new GeoPoint((int)(location.getLatitude()*1.0E6),(int)(location.getLongitude()*1.0E6)), dest); 
                        }
                        catch (NullPointerException e){ }
                    }
                    else
                    {   return null;
                    }
                }
                else
                {   return null; }

                return null;
                }
