How to handle screen orientation change when progress dialog and background thread active?

by

Edit: Google engineers do not recommend this approach, as described by Dianne Hackborn (a.k.a. hackbod) in this StackOverflow post. Check out this blog post for more information.

You have to add this to the activity declaration in the manifest:

android:configChanges="orientation|screenSize"

so it looks like

<activity android:label="@string/app_name" 
        android:configChanges="orientation|screenSize|keyboardHidden" 
        android:name=".your.package">

The matter is that the system destroys the activity when a change in the configuration occurs. See ConfigurationChanges.

So putting that in the configuration file avoids the system to destroy your activity. Instead it invokes the onConfigurationChanged(Configuration) method.
