1 2 Android LNotifications Sample Sample 3 =================================== 4 5 This sample demonstrates new features for notifications introduced in Android L. 6 These features include heads-up notifications, visibility, people, category and priority 7 metadata. 8 9 Introduction 10 ------------ 11 12 Android 5.0 (Lollipop, API level 21) introduced additional features to the Notification API. 13 Specifically, it allows developers to specify the priority and visibility level for 14 notifications. This metadata allows the system to provide enhanced security for notifications 15 while the lock screen is active, allows high-priority notifications to appear even when 16 the notification bar is closed, and provides users to silence low-priority notifications 17 when they're busy. 18 19 This metadata is provided via additional arguments to the `Notification.Builder` class. 20 21 Specifically, this sample demonstrates how to generate a heads-up notification 22 (`HeadsUpNotificationFragment`), how to control visibility on the lock screen 23 (`VisibilityMetadataFragment`), and how to set the category, priority, and associated contact 24 for a notification (`OtherMetadataFragment`). 25 26 Pre-requisites 27 -------------- 28 29 - Android SDK 24 30 - Android Build Tools v24.0.1 31 - Android Support Repository 32 33 Screenshots 34 ------------- 35 36 <img src="screenshots/1-headsup.png" height="400" alt="Screenshot"/> <img src="screenshots/2-visibility.png" height="400" alt="Screenshot"/> <img src="screenshots/3-others.png" height="400" alt="Screenshot"/> 37 38 Getting Started 39 --------------- 40 41 This sample uses the Gradle build system.
