@ohos.notification (Notification)

The Notification module provides notification management capabilities, covering notifications, notification slots, notification subscription, notification enabled status, and notification badge status.

Since API version 9, this module is no longer maintained. It is recommended that you use @ohos.notificationManager instead.

The initial APIs of this module are supported since API version 7. Newly added APIs will be marked with the superscript to indicate their earliest API version.

Notification subscription and unsubscription are open only to system applications.
