Android app do something on close service/app

Question

I have an app which has a queue in the background to do something. I also have a service which shows and updates a notification in the notification-center about the progress of the queue (because it is not depending on a certain activity).

Notification be like: "there are 4 items left".

All works great except the app is destroyed (by the user and/or system).

I want to update the notification bevore the app or the service is closed (to something like "come back, you missed some items"). I know there is no "close"-event for an application and the "destroyed" event from the service is not called in this case.

I'm working with Xamarin.

What can I do to achive this? Any ideas? Thanks

I tried this. But I need to know, when the user or the system closes my app. Is there no way? — Joehl, Feb 18 '15 at 10:04
Yes. But it is never called when I close the app from the "open-apps-list". So I think there is no way.. all searchin in the web gave me the same.. — Joehl, Feb 18 '15 at 10:21
why your service is closing are you doing any overloaded work in the service? — KomalG, Feb 18 '15 at 10:33

You can initiate your background service using Alarm Manager even if it is killed. I have faced the same problem when I had to update the user's current location. I set an infinite alarm which starts android service if its not started in every five minutes. You can give it a try.
