Auto Notification for Android

I'm new with Android programming. I'm just wondering whether its possible to set up 开发者_StackOverflowauto notification. For example, every morning at 8am, the app will send a notification to user about something. Is this possible? Which area/class of Android programming should I look at? Thanks!

You should have a look at the Alarm Manager. You will need to use either of the 'set' methods, and give it a PendingIntent that will perform a broadcast or start an intent service that wakes up just to show the notification. For the broadcast, you will need to have a receiver in your app, that makes a Notification and shows it.
