The most proper way to this is to use a fragment to retain the instance of the async task, over rotations.

Here is a link to very simple example making it easy to follow and integrate this technique into your apps. This works brilliantly all buttons and images etc are redrawn as expected

use 

android:configChanges="keyboardHidden|orientation"

as a attribute of your Activity in AndroidManifest.xml file to prevent reload Activity on screen rotation .

I think exception is due to the re starting of the activity in orientation changes, if use android:configChanges="orientation|keyboardHidden" for your activity in your manifest, which prevents restart
