There are lots of reasons why detecting if application is on foreground. for example - as a trigger to GCM/C2DM push notification - lot's of apps would have good reason implementing different behavior when app is foreground and background.

My question is, when I start an activity without any interaction with DefaultApplication , will my DefaultApplication 's onCreate() get called

I want to check if the app is running in the background. In: locationManagerDidUpdateLocation { if(app is runing in background){ do this } } DavidN App delegate gets callbacks indicating state transitions. You can track it based on that.
