There are many, many apps on the Play Store that do this already. > When a user presses back key while countdown, after a some time > one can ALWAYS hear a ringtone, but there is no way to return to the > application. So, you have a bug in your app. If the user presses BACK, one of two things should happen: 1. The countdown stops 2. The countdown continues, where the countdown is managed by a service, possibly with an associated Notification to allow the user to launch an activity to stop the countdown > When I launch the app second time I see that there is 2 > instances of the app (I'm using getInstancesCount() ). First, app != activity. They are not even spelled the same. Second, getInstanceCount() has been removed from the SDK, and so your app will crash on API Level 11+. > My problem is how to get back to this "frozen" app instead of launching its > new instance. You can't. Your first instance of the activity leaked stuff. Don't do that. If you wish the countdown to continue past a BACK press, have the countdown by managed by a service, such that a new activity can then tell the service to stop, etc. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android Training in NYC: http://marakana.com/training/android/ -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
