Again, driving your UI based on whether some other part of it is stopped is probably NOT the right way to go about it.
In the example here, it is completely irrelevant. Your problem is that you have two activities with the same task affinity being launched as top-level items. Please read the docs on tasks and activities: http://developer.android.com/guide/topics/fundamentals.html#acttask For the specific case of an activity being launched from receiving an SMS, you probably want to give that an empty task affinity so that it is not considered part of your main application flow. You can look at many of the standard applications to see approaches to handling entry to them from multiple places -- for example Calendar allowing you to see upcoming events from the status bar, or music with its now playing screen you can get to from the status bar.
