Badge

A badge is an image displayed on the application icon, which informs the user about notifications and events.

To create a badge, use the badge_add() method. The application that creates the badge can also update and remove it. When applications are signed with the same certificate, they can control each other's badges.

If an application not signed with the same certificate must be allowed manage a badge, use the badge_add() method with a writable application ID. The writable application ID enables another application to control your application to manage the badge. You can also configure your application to handle the badge itself.
