Known Direct Subclasses

PlaybackBannerControlGlue, PlaybackTransportControlGlue

PlaybackBannerControlGlue	A helper class for managing a `PlaybackControlsRow` being displayed in `PlaybackGlueHost`.
PlaybackTransportControlGlue	A helper class for managing a `PlaybackControlsRow` being displayed in `PlaybackGlueHost`, it supports standard playback control actions play/pause, and skip next/previous.

A base abstract class for managing a PlaybackControlsRow being displayed in PlaybackGlueHost. It supports standard playback control actions play/pause and skip next/previous. This helper class is a glue layer that manages interaction between the leanback UI components PlaybackControlsRowPlaybackRowPresenter and a functional PlayerAdapter which represents the underlying media player.

The app must pass a PlayerAdapter in constructor for a specific implementation e.g. a MediaPlayerAdapter.

The glue has two action bars: primary action bars and secondary action bars. Apps can provide additional actions by overriding onCreatePrimaryActions and / or onCreateSecondaryActions and respond to actions by overriding onActionClicked(Action).

The subclass is responsible for implementing the "repeat mode" in onPlayCompleted().
