Notifying the User

A notification is a user interface element that you display outside your app's normal UI to indicate that an event has occurred. Users can choose to view the notification while using other apps and respond to it when it's convenient for them.

The Notifications design guide shows you how to design effective notifications and when to use them. This class shows you how to implement the most common notification designs.
