Android :: Keeping Notification At The Status Bar After Service That Spawned Stops

I have a main application, that at some point spawns a service that checks for updates, if it finds any, it posts a notification with the ink to the update, and then the update service stops. Through the debugger I've noticed that the notification pops up but then disappears once my service is stopped, which I guess makes sense since the Notification object was instantiated within that service. What would be the best practice of keeping that notice available until the user clicks it?

1) somehow attaching the notification to my top service - which might get really ugly --> since that update service is spawned by another sub-service that is spawned by a broadcast receiver... so even if i wanted to somehow pass the object of my top level service it would mess the entire abstraction of my app structure and would force me to keep pointers to it through every event and service that I use... Perhaps there is some other way to get that service through the app's context? or any other alternative?

2) Finding a way to keep my update-service alive until the user presses the notification, but I'm not sure if there is any intent broadcasted that I could listen to...
