Removing Notification

• The user dismisses the notification either individually or by using "Clear All" (if the notification can be cleared).

• The user clicks the notification, and you called setAutoCancel() when you created the notification.

• You call cancel() for a specific notification ID. This method also deletes ongoing notifications.

• You call cancelAll(), which removes all of the notifications you previously issued.

Bundled Notifications

ApplicationCompat.Builder.setGroup(String);

Setting Visibility

You call setVisibility() and specify one of the following values:

• VISIBILITY_PUBLIC shows the notification's full content.

• VISIBILITY_SECRET doesn't show any part of this notification on the lock screen.

• VISIBILITY_PRIVATE shows basic information, such as the notification's icon and the content title, but hides the notification's full content.

Using Static Shortcuts

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.myapplication"> <application ... > <activity android:name="Main"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> <meta-data android:name="android.app.shortcuts" android:resource="@xml/shortcuts" /> </activity> </application> </manifest>

Using Dynamic Shortcuts

Dynamic shortcuts should provide links to specific, context-sensitive actions within your app. These actions can change between uses of your app, and they can change even while your app is running. Good candidates for dynamic shortcuts include calling a specific person, navigating to a specific location, and viewing the current score for a specific game.

The ShortcutManager API allows you to complete the following operations on dynamic shortcuts:

• Publish: Use setDynamicShortcuts(List) to redefine the entire list of dynamic shortcuts, or use addDynamicShortcuts(List) to augment an existing list of dynamic shortcuts.

• Update: Use the updateShortcuts(List) method.

• Remove: Remove a set of dynamic shortcuts using removeDynamicShortcuts(List), or remove all dynamic shortcuts using removeAllDynamicShortcuts().

Image Keyboard Support

• Enhanced Live Wallpaper Metadata

• Round Icon Resources

When a launcher requests an app icon, the framework returns either android:icon or android:roundIcon, depending on the device build configuration.

• Storage Manager Intent

• Improved VR Thread Scheduling

• Demo User HintApps can now check to see if the device is running as the demo user.

• APIs for Carriers and Calling Apps

• New Screen Densities for Wear Devices

• DENSITY_260

• DENSITY_300

• DENSITY_340
