Removing the dialog in onPause is too late, because by that time the
managed dialogs have been alerady saved (around the time of
onSaveInstanceState callback).
If you don't want the dialog to persist through orientation changes,
don't use a managed dialog.
Create one without calling showDialog, save the reference as an instance
variable of your activity, and dismiss it in onPause.

I am seeing that a ProgressDialog is persisting after a screen
rotation, even though I am calling dismissDialog in the onPause
method. I do know that a new Activity is created after the screen
rotation and I have read threads like

However, my scenario is simpler in that there is no background task
which holds onto the old Activity. Any ideas?
Thanks
