What are notifications?
Android and Android apps can notify users of information and events by putting an alert in the "Notification bar". This appears as a narrow bar across the top of the screen with small icons. When the user pulls down the bar it expands into the notification area, a scrollable area containing messages for the user. Tapping on a notification generally opens the app.
