Diane it does have a public "setIndeterminateDrawable" - I can set it with a RotateDrawable and it works to spin whatever I want there... which is cool and easy... it just apparently does it clockwise only... I just need to replace it with something that can spin stuff backwards.... and I need to learn the other stuff anyway.
