No, because "this" will point to two different applications, and they will each get their local copy. One can use PreferenceManager.getDefaultSharedPreferences(this). The other will need to construct a fully-qualified path to the other app's copy of the SharedPreferences XML file and use some constructor or something on SharedPreferences to access the data. Or, worst-case, it would need to manually parse the XML. Since SharedPreferences are stored in XML and not in SQLite, I am very very nervous about problems with sharing them between processes. -- Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Books: http://commonsware.com/books.html --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
