How to handle screen orientation change when progress dialog and background thread active?

Question

My program does some network activity in a background thread. Before starting, it pops up a progress dialog. The dialog is dismissed on the handler. This all works fine, exc

The original perceived problem was that the code would not survive a screen orientation change. Apparently this was "solved" by having the program handle the screen orientation change itself, instead of letting the UI framework do it (via calling onDestroy)).

I would submit that if the underlying problem is that the program will not survive onDestroy(), then the accepted solution is just a workaround that leaves the program with serious other problems and vulnerabilities. Remember that the Android framework specifically states that your activity is at risk for being destroyed almost at any time due to circumstances outside your control. Therefore, your activity must be able to survive onDestroy() and subsequent onCreate() for any reason, not just a screen orientation change.

If you are going to accept handling screen orientation changes yourself to solve the OP's problem, you need to verify that other causes of onDestroy() do not result in the same error. Are you able to do this? If not, I would question whether the "accepted" answer is really a very good one.
