Android - can service be run in untill app gets uninstalled?

Question

I need to get notified when phone contacts changed, even if my app is closed. how to do?

In my code I am starting service with START_STICKY in splash screen, but when I close the app, service also starting again.

When I change in contacts, ContentObserver class's onchange called multiple times.

And some time onchange is not being called. So how to achieve solution?
