Your "whole application is closed" in all cases you have cited here. Your process is being terminated by the task manager, as you can tell by the fact that your global variables have been cleared. Your problem is that you are assuming that those global variables always exist and that users are always coming into your application through one path that sets up those variables. That is not necessarily a valid assumption -- recent tasks is just one example of a way the user can "deep link" elsewhere in your application. One way or another, you need to handle the case where users return to your app, running in a fresh process, but are not coming into your launcher activity. -- 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 3.8 Available! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
