Hi Mark, thanks for your swift reply. I thought my AsyncTask got destroyed somehow, but from your response it seems like just my ProgressDialog got dismissed. Is there a way I can prevent that? I want the computation in AsyncTask to be done before user can interact with the UI again.
And second question, can I override the back button somehow so I could catch the call in my AsyncTask and cancel it?
