I use configChanges="locale" on my activities. Without this options in AndroidManifest.xml in 2.x i get flickering screens.
It works in all my activities excepting in the preferences screen i add programatically. I have one Preference Activity --> it works after setting configChanges="locale" to the AndroidManifest.xml.
Inside of the Preference Activity i add programatically a new preferencescreen. For this new PreferenceScreen i dont have an activity in the AndroidManifest.xml! So i cannot add the configChanges="locale" and the screen flickers on 2.x !!
How can i add the attribute configChanges="locale" programatically?
