Prevent change of orientation update Activity

I have a problem, an Activity my has a list of multi-selectable objects, with the long click I can select several of these objects and click the remove button, when I click to remove, a progress dialog appears that is executed by an AssyncTask .

The problem is that when I change the orientation of the smartphone (either it changes to portrait or landscape) the view is updated, and this causes the thread to stop causing an error, how do I prevent this error? Or prevent assynctask from stopping without having to set an orientation?

Error:

java.lang.IllegalArgumentException

To solve this problem open the file AndroidManifest.xml , hence in the declaration of your activity add the following line:

android:configChanges="orientation|screenSize"

Example:

<activity
    android:name="com.example.activity.MainActivity"
    android:configChanges="orientation|screenSize"
    android:label="@string/app_name" >
</activity>
