3.14. Media UI

If device implementations include the UI framework that supports third-party apps that depend on MediaBrowser and MediaSession , they:

• [C-1-1] MUST display MediaItem icons and notification icons unaltered.
• [C-1-2] MUST display those items as described by MediaSession, e.g., metadata, icons, imagery.
• [C-1-3] MUST show app title.
• [C-1-4] MUST have a drawer or other mechanism to present MediaBrowser hierarchy and provide user affordance for the MediaBrowser hierarchy.
• [C-1-5] MUST consider double tap of KEYCODE_HEADSETHOOK or KEYCODE_MEDIA_PLAY_PAUSE as KEYCODE_MEDIA_NEXT for MediaSession.Callback#onMediaButtonEvent.
