The best answer is to not do that, but to use registerOnSharedPrefereneChangeListener() to be notified of any changes. Beyond that, you override onBackPressed() like you would in any Android activity (and also onKeyDown() if you are on Android 1.6 or earlier). > also, what's the interface to cancel the changes from these > PreferenceActivities. You don't. If you didn't want the change, you should not have displayed the PreferenceActivity in the first place. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _The Busy Coder's Guide to *Advanced* Android Development_ Version 1.9 Available! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
