Question

It seems when screen orientation changes, the activity’s onCreate() method is called. In my onCreate() method, I have an AlertDialog which pops up when the activity is called. The problem is when I switch the screen sideways, the popup is displayed again.

How can I avoid this?

Answer 1

Modify your AndroidManifest with:

android:configChanges="orientation|keyboardHidden"

Your Activity should look like this:

<activity android:name=".activities.MyActivity"
                  android:label="@string/my_activity_name"
                  android:configChanges="orientation|keyboardHidden"/>

This will avoid the call to onCreate() when there is a change in the orientation.
