Answer by Gotcha for Background task, progress dialog, orientation change - is there any 100% working solution?

This is my solution: https://github.com/Gotchamoh/Android-AsyncTask-ProgressDialog

Basically the steps are:

1. I use onSaveInstanceState to save the task if it is stillprocessing.
2. In onCreate I get the task if it was saved.
3. In onPause I discard the ProgressDialog if it is shown.
4. In onResume I show the ProgressDialog if the task is stillprocessing.
