Android LNotifications Sample Sample
|
|
===================================
|
|
|
|
This sample demonstrates new features for notifications introduced in Android L.
|
|
These features include heads-up notifications, visibility, people, category and priority
|
|
metadata.
|
|
|
|
Introduction
|
|
------------
|
|
|
|
Android 5.0 (Lollipop, API level 21) introduced additional features to the Notification API.
|
|
Specifically, it allows developers to specify the priority and visibility level for
|
|
notifications. This metadata allows the system to provide enhanced security for notifications
|
|
while the lock screen is active, allows high-priority notifications to appear even when
|
|
the notification bar is closed, and provides users to silence low-priority notifications
|
|
when they're busy.
|
|
|
|
This metadata is provided via additional arguments to the `Notification.Builder` class.
|
|
|
|
Specifically, this sample demonstrates how to generate a heads-up notification
|
|
(`HeadsUpNotificationFragment`), how to control visibility on the lock screen
|
|
(`VisibilityMetadataFragment`), and how to set the category, priority, and associated contact
|
|
for a notification (`OtherMetadataFragment`).
|
|
