That sounds like: -- the "setup screen" should be a PreferenceActivity -- the main activity should load its preferences in onStart(), or use a preference-change listener, to pick up the changed preferences If, for whatever reason, you want to collect preferences by means other than the preferences system, and so your setup screen is just an ordinary activity, have the main activity use startActivityForResult() and have the setup screen use setResult() to pass back the data via Intent extras. However, I really recommend that preferences be collected by the preference system wherever possible. People bitch and moan about how Android applications have no consistent UI. Preferences is one of the few places where Android makes it relatively painless to offer a consistent UI. -- 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 Android Development_ Version 3.1 Available! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
