Scalilng Overlays

I'm attempting to scale an overlay image for a map to make it the correct size. Eventually I'll need to do the dynamically for when the user zooms in and out.

I attempted to use ScaleDrawable like so, but this causes a crash:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
        Drawable myIcon = getResources().getDrawable(R.drawable.large); 
 
        ScaleDrawable z19 = new ScaleDrawable(myIcon, 0, 500, 500);
 
        MapController mapController = mapview.getController();
 
        mapController.setZoom(19);
 
        mapController.setCenter(centerCM);
 
        List<Overlay> l = mapview.getOverlays();
 
        l.add(new MapOverlay((Drawable) z19, mapview));
 
Parsed in 0.032 seconds,  using GeSHi 1.0.8.4

If on the last line I use myIcon instead of z19, there are no problems (other than the overlay not being the desired size).

Adb isn't telling me anything at the moment.

Appreciate any suggestions!

Nevermind, realized SetBound does what I need.
