Answer 1

Make a class that extends Overlay and add it as overlay. In tha class you override

@Override
public void draw(Canvas c, MapView mapView, boolean shadow) {
  //super.draw(c, mapView, shadow);

  if (shadow) return; // no shadows

  Rect canvasRekt = new Rect(0, 0, c.getWidth(), c.getHeight());
  Rect kortRekt = ...

  c.drawBitmap(overlejretKort, canvasRekt, kortRekt, paint);
  c.drawRect(kortRekt, paint);
}

The kortRekt should contain the rectangle of your bitmap (here its called overlejretKort)
