Android Application object life cycle

Question

I can't find the Application's object (extend Application) life cycle. For example, what happens if I have a broadcast receiver which is called through Alarm. Will methods in Application being called? Or is everything independent from the Application? If I have a datahelper instantiated in the Application and I call it from broadcast receiver, will it available? Which is the Application object life cycle, when it is destroyed? when is it called when using Alarms? What happens when the activity is not in foreground with the Application object? Thanks in advance. Guillermo.

Look at it this way: before everything else, there is Application. It is created before your BroadcastReceiver, before your Activity instances, before your Service instances, etc. It doesn't matter whether anything is in the foreground. The application will be terminated when all of your Activity instances are gone, when you're out of your BroadcastReceiver and once your Service instances are terminated. There's no guarantee that it will be killed, but it is the last thing to go when the OS decided that your app must die.
