Is there any way to post notification when app goes to background?

The notification API doesn't provide information to do such thing, Alarm API can't provide what I need, and Calendar API is too much for what I need. And I can't afford web services.

I just need to notify the user to do something after a period of time when the app goes to background, is there any work around to do that with only notification API and a simple app?

Thanks,
