Notifications

There are a few changes to the notifications feature, as follows:

The Notification.setLatestEventInfo() method is now removed. When constructing notifications, we must use the Notification.Builder class.

Updating a notification is also done via the Notification.Builder instance using the same instance of the builder, and calling the build() method will get us an updated Notification instance. If legacy support is required, you can use NotificationCompat.Builder instead, which is available in the Android Support Library.

The adb shell dumpsys notification command no longer prints out notification text. The proper usage now is adb shell dumpsys notification --noredact.

The newly added INTERRUPTION_FILTER_ALARMS filter level corresponds to a new mode: Alarms only do not disturb.

The newly added CATEGORY_REMINDER category is used for user-scheduled reminders.

The newly added Icon class allows icons to be attached to notifications via the setSmallIcon() and setLargeIcon() methods.

The updated addAction()method now accepts an Icon object instead of a drawable resource ID.

The newly added getActiveNotifications() method allows you to find out which notifications are currently alive.

We can obtain some knowledge about what the user is and is not expecting to see under notifications when using the following methods:The newly added getCurrentInterruptionFilter() method returns the current notification interruption filter in which notifications are allowed to interrupt the user

The newly added getNotificationPolicy() method returns the current notification policy
