Thanks Mark. To access my preferences outside my PreferenceActivity in another Activity or a Service can I use PreferenceManager. getDefaultSharedPreferences() also?
In your code here: http://github.com/commonsguy/cw-android/blob/master/Prefs/Dialogs/src/com/commonsware/android/prefdialogs/DialogsDemo.java I see SharedPreferences prefs=PreferenceManager is used, is that correct? Should I use it like that to retrieve my preferences eslewhere in my application?
