thanks for the tips, Mark. I'll play with it. It might need to be an animation list or whatever
btw - RotateDrawable would be a two-line way to do it (custom little icon seems to get animated fine) to replace the indeterminate drawable, but RotateDrawable seems to insist on rotating clockwise, too... it sets toDegrees to max (fromDegrees, toDegrees), so you can't specify it go from 360 to 0. Dianne - in looking at your note again, I can't tell if you were suggesting that the best thing to do (for someone want to do this in the first place) would be to replace the progress bar functionality wholesale (yes overkill). Of course I want to avoid depending on internals or anything else in the API susceptible to change.
