Try this answer, which contains a code example for using a ProgressDialog with AsyncTask.

Try to read this article, it describes how to use AsyncTask with ProgressDialog.

If you haven't already, you should check out this page on the Android developers site. It not only gives the javadocs for asynctask, but it explains how to use it.
