3.8. User Interface Compatibility

3.8.1. Launcher (Home Screen)

Android includes a launcher application (home screen) and support for third-party applications to

replace the device launcher (home screen).

If device implementations allow third-party applications to replace the device home screen, they:

[C-1-1] MUST declare the platform feature android.software.home_screen .

[C-1-2] MUST return the AdaptiveIconDrawable object when the third party application use

<adaptive-icon> tag to provide their icon, and the PackageManager methods to retrieve icons

are called.

If device implementations include a default launcher that supports in-app pinning of shortcuts, they:

[C-2-1] MUST report true for ShortcutManager.isRequestPinShortcutSupported() .

[C-2-2] MUST have user affordance asking the user before adding a shortcut requested by

apps via the ShortcutManager.requestPinShortcut() API method.

[C-2-3] MUST support pinned shortcuts and dynamic and static shortcuts as documented

on the App Shortcuts page .

Conversely, if device implementations do not support in-app pinning of shortcuts, they:

[C-3-1] MUST report false for ShortcutManager.isRequestPinShortcutSupported() .

If device implementations implement a default launcher that provides quick access to the additional

shortcuts provided by third-party apps through the ShortcutManager API, they:

[C-4-1] MUST support all documented shortcut features (e.g. static and dynamic

shortcuts, pinning shortcuts) and fully implement the APIs of the ShortcutManager API

class.

If device implementations include a default launcher app that shows badges for the app icons, they:

[C-5-1] MUST respect the NotificationChannel.setShowBadge() API method. In other words,

show a visual affordance associated with the app icon if the value is set as true , and do

not show any app icon badging scheme when all of the app's notification channels have

set the value as false .
