What happens to Application after IntentService is killed because of no requests to it

Issue

I read about IntentService and wonder about it´s lifestyle and effect on the Android Application. I know when the IntentService starts Android first starts the android.app.Application by running onCreate() . When the IntentService running queue is empty the IntentService can be killed. But what happens then to the started android.app.Application?

Solution

The Application class is a Singleton and will exist as long as your app's process still exits. The IntentService exits on its own once the are no more Intents for it to handle, but that does not mean the app process exits. Read about processes and threads here to get more information: https://developer.android.com/guide/components/processes-and-threads.html
