after a brief period of time, and use the TYPE_APPLICATION_OVERLAY window type API to display

alert windows as an overlay over other apps.

If device implementations include a screen or video output, they:

[C-1-1] MUST provide a user affordance to block an app from displaying alert windows

that use the TYPE_APPLICATION_OVERLAY . The AOSP implementation meets this

requirement by having controls in the notification shade.

[C-1-2] MUST honor the Toast API and display Toasts from applications to end users in

some highly visible manner.

3.8.6. Themes

Android provides “themes” as a mechanism for applications to apply styles across an entire Activity

or application.

Android includes a “Holo” and "Material" theme family as a set of defined styles for application

developers to use if they want to match the Holo theme look and feel as defined by the Android SDK.

If device implementations include a screen or video output, they:

[C-1-1] MUST NOT alter any of the Holo theme attributes exposed to applications.

[C-1-2] MUST support the “Material” theme family and MUST NOT alter any of the Material

theme attributes or their assets exposed to applications.

Android also includes a “Device Default” theme family as a set of defined styles for application

developers to use if they want to match the look and feel of the device theme as defined by the

device implementer.

Device implementations MAY modify the Device Default theme attributes exposed to

applications.

Android supports a variant theme with translucent system bars, which allows application developers

to fill the area behind the status and navigation bar with their app content. To enable a consistent

developer experience in this configuration, it is important the status bar icon style is maintained

across different device implementations.

If device implementations include a system status bar, they:

[C-2-1] MUST use white for system status icons (such as signal strength and battery

level) and notifications issued by the system, unless the icon is indicating a problematic

status or an app requests a light status bar using the

SYSTEM_UI_FLAG_LIGHT_STATUS_BAR flag.

[C-2-2] Android device implementations MUST change the color of the system status

icons to black (for details, refer to R.style ) when an app requests a light status bar.

3.8.7. Live Wallpapers

Android defines a component type and corresponding API and lifecycle that allows applications to

expose one or more “Live Wallpapers” to the end user. Live wallpapers are animations, patterns, or

similar images with limited input capabilities that display as a wallpaper, behind other applications.

Hardware is considered capable of reliably running live wallpapers if it can run all live wallpapers,

with no limitations on functionality, at a reasonable frame rate with no adverse effects on other

applications. If limitations in the hardware cause wallpapers and/or applications to crash,

malfunction, consume excessive CPU or battery power, or run at unacceptably low frame rates, the

hardware is considered incapable of running live wallpaper. As an example, some live wallpapers
