*** ** * ** ***
A base abstract class for managing a[PlaybackControlsRow](https://developer.android.com/reference/kotlin/androidx/leanback/widget/PlaybackControlsRow)being displayed in[PlaybackGlueHost](https://developer.android.com/reference/kotlin/androidx/leanback/media/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[PlaybackControlsRow](https://developer.android.com/reference/kotlin/androidx/leanback/widget/PlaybackControlsRow)[PlaybackRowPresenter](https://developer.android.com/reference/kotlin/androidx/leanback/widget/PlaybackRowPresenter)and a functional[PlayerAdapter](https://developer.android.com/reference/kotlin/androidx/leanback/media/PlayerAdapter)which represents the underlying media player.
The app must pass a[PlayerAdapter](https://developer.android.com/reference/kotlin/androidx/leanback/media/PlayerAdapter)in constructor for a specific implementation e.g. a[MediaPlayerAdapter](https://developer.android.com/reference/kotlin/androidx/leanback/media/MediaPlayerAdapter).
The glue has two action bars: primary action bars and secondary action bars. Apps can provide additional actions by overriding[onCreatePrimaryActions](https://developer.android.com/reference/kotlin/androidx/leanback/media/PlaybackBaseControlGlue#onCreatePrimaryActions(androidx.leanback.widget.ArrayObjectAdapter))and / or[onCreateSecondaryActions](https://developer.android.com/reference/kotlin/androidx/leanback/media/PlaybackBaseControlGlue#onCreateSecondaryActions(androidx.leanback.widget.ArrayObjectAdapter))and respond to actions by overriding[onActionClicked](https://developer.android.com/reference/kotlin/androidx/leanback/media/PlaybackBaseControlGlue#onActionClicked(androidx.leanback.widget.Action)).
The subclass is responsible for implementing the "repeat mode" in[onPlayCompleted](https://developer.android.com/reference/kotlin/androidx/leanback/media/PlaybackBaseControlGlue#onPlayCompleted()).
