here is my way, just a suggestion:) 1. if the activity is not in active, start it and show the unread messages; 2. if the activity in front, hook the database changes, just show a message in the activity not the state bar. 3. switch the char window(with deffrient buddy) by popup menu(a dialog) or system menu or tabset in one activity not many activity
