It is working now. This code fix made it work. It is not possible to
get the resources directly in the
wallpaper service class, because that results in a nullpoint
exception. The resources have to be fetched in the renderer class, to
avoid the nullpoint exception.
in wallpaper service class:
-------------------
renderer = new GlRenderer(this);
in renderer class:
----------------
private Context context;
public GlRenderer(Context context) {
this.context = context;
((GL11) (gl)).glEnable(GL10.GL_BLEND);
bitmap1 = BitmapFactory.decodeResource(context.getResources(),
R.drawable.l11);
