Android :: ProgressDialog Created From OnCreateDialog Stops Animating On Second Run

I create a ProgressDialog in onCreateDialog() like so:

code:.........

Android, in its wisdom (or serious lack of it) decides to cache every dialog created through onCreateDialog(). Because of that, any subsequent call to showDialog(DIALOG_PROGRESS_ID) results in the same ProgressDialog instance being used but the animation has stopped working.

I've tried to re-set indeterminate in onPrepareDialog(), but that doesn't do anything. There is likewise no obvious method to call on the dialog instance that will reset the animation.

code:................

But maybe there is a way to get the ProgressBar itself and start it animating? so I tried the following after I asked this question:

code:........

But it didn't work either!

So, does anyone know if there is a way to restart animation on a ProgressDialog? If not, is there a way that I can force every showDialog() call to call onCreateDialog()? (this second question was answered by @TuomasR, but after pondering it I don't think this is a very good solution to my problem)
