Often times, applications will perform some background operation-maybe while the app is running or maybe triggered on a scheduled alarm. The user won't know what's going on, though, unless they are informed of some event. Luckily, Android has an easy notification system that allows applications to display a message in the status bar and provide informative details to the user when something important occurs.

In this tutorial, we'll extend the existing unnamed "TutList" application to notify the user when the scheduled download of tutorials has taken place. When the user taps on the notification in the status bar, the application will be launched. This way, we use notifications to provide feedback to the user that something has happened, while also reminding he user of the existence of the application and that fresh content is available.
