Status bar – Event-driven notification

It works like this:

Status bar - Event Driven

  1. One-time events such as an incoming email can be brought to the attention of the user by an event-driven status bar notification. When a notification is initiated, the icon and the title flash in the status bar once

  2. After this, the icon is displayed in the status bar.

  3. The status bar can be pulled down to reveal the window shade. Expanded messages for the notifications are shown. Event-driven notifications (for example an email) are displayed under the ‘notifications’ bar when ongoing notifications are also present.

  4. An expanded message can be tapped, upon which the corresponding app is opened, or…

  5. …the user can tap the ‘clear’ button to dismiss the notification.

  6. When the notification is dismissed, the window shade is closed and the icon is cleared form the status bar

Use when

When your app needs to notify a user about an event that requires a response, you can use event-driven notifications. The notifications should be accumulative, e.g. a number of emails should be shown in the notification, instead of adding a separate notification for every email.
Status bar notifications can be used if your app is not active. If you require an immediate response when your app is active, consider using a alert dialog. If you need a notification that cannot be dismissed, consider using an ongoing notification.

The Good

  • User is not disturbed in their current activity
  • Provides a way of notifying the user when your app is not active
  • Provides a direct shortcut to the app

Add Good

The Bad

  • Might not be noticed (immediately) by the user
  • Can be dismissed without reading
