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

Question

I download some data from internet in background thread (I use AsyncTask) and display a progress dialog while downloading. Orientation changes, Activity is rest

Answer 1

you should call all activity actions using activity handler. So if you are in some thread you should create a Runnable and posted using Activitie's Handler. Otherwise your app will crash sometimes with fatal exception.
