I am using a URL connection to connect Google maps web service and get the result in KML format and parse it and display it on MapView. I put this operations in a thread, but I get this error that I don’t know what does it mean ?!
please help me in finding out what is this error and what is the solution ?

Edit
I have changed the code to the following .. but still have the same error
private void initMap(){
new DrawRoad().execute("");
}
private class DrawRoad extends AsyncTask<String, Void, Road> {
protected Road doInBackground(String... unused) {
mapOverlays = mapView.getOverlays();
double fromLat = 49.85, fromLon= 24.016667, toLat = 50.45, toLon = 30.523333;
String url = RoadProvider.getUrl(fromLat, fromLon, toLat, toLon);
InputStream is = getConnection(url);
mRoad = RoadProvider.getRoute(is);
return mRoad;
}
protected void onPostExecute(Road road) {
drawable = getResources().getDrawable(R.drawable.marker);
itemizedOverlay2 = new MyItemizedOverlay(drawable, mapView,road);
mapOverlays.clear();
for(int i=0; i<mRoad.mRoute.length;i++){
addPoint("","",new GeoPoint((int)(road.mRoute[i][1]*1E6),(int)(road.mRoute[i][0]*1E6)),itemizedOverlay2);
}
//addPoint("Point 2.","Point 2.",(int)(51.515259*1E6),(int)(-0.086623*1E6),itemizedOverlay2);
mapOverlays.add(itemizedOverlay2);
mapView.invalidate();
}
}
You could try using an async task which is simpler, something like:
