In my experience it is better to create different sized bitmaps for each density you are targeting. That way you don't have to worry about these scale attributes and get crisp results on any device.

These scale attributes are not defined for BitmapDrawables. They exist for ScaleDrawables which are meant to scale another drawable. Have a look at:
