Progress bar not updating after screen orientation changed
<p>While developing an android application I have constructed an activity that contains a progress bar.
There is an async task that will update the progress bar in an activity. After the screen orientation changed, The progress bar not longer get updated while the async task still in progress. I believe the async task is not referencing to the new progress bar instance that was created when android invoke onCreate method after screen orientation changed.</p>

<p>Appreciate if anyone can show me any tip for this.</p>

<p>Thanks.</p>
