+/**
+ * A helper class for managing a {@link android.support.v17.leanback.widget.PlaybackControlsRow} and
+ * {@link PlaybackOverlaySupportFragment} that implements a recommended approach to handling standard
+ * playback control actions such as play/pause, fast forward/rewind at progressive speed levels,
+ * and skip to next/previous. This helper class is a glue layer in that it manages the
+ * configuration of and interaction between the leanback UI components by defining a functional
+ * interface to the media player.
+ *
+ * <p>You can instantiate a concrete subclass such as {@link MediaControllerGlue} or you must
+ * subclass this abstract helper. To create a subclass you must implement all of the
+ * abstract methods and the subclass must invoke {@link #onMetadataChanged()} and
+ * {@link #onStateChanged()} appropriately.
+ * </p>
+ *
+ * <p>To use an instance of the glue layer, first construct an instance. Constructor parameters
+ * inform the glue what speed levels are supported for fast forward/rewind. Providing a
+ * {@link android.support.v17.leanback.app.PlaybackOverlaySupportFragment} is optional.
+ * </p>
+ *
+ * <p>If you have your own controls row you must pass it to {@link #setControlsRow}.
+ * The row will be updated by the glue layer based on the media metadata and playback state.
+ * Alternatively, you may call {@link #createControlsRowAndPresenter()} which will set a controls
+ * row and return a row presenter you can use to present the row.
+ * </p>
+ *
+ * <p>The helper sets a {@link android.support.v17.leanback.widget.SparseArrayObjectAdapter}
+ * on the controls row as the primary actions adapter, and adds actions to it. You can provide
+ * additional actions by overriding {@link #createPrimaryActionsAdapter}. This helper does not
+ * deal in secondary actions so those you may add separately.
+ * </p>
+ *
+ * <p>Provide a click listener on your fragment and if an action is clicked, call
+ * {@link #onActionClicked}. There is no need to call {@link #setOnItemViewClickedListener}
+ * but if you do a click listener will be installed on the fragment and recognized action clicks
+ * will be handled. Your listener will be called only for unhandled actions.
+ * </p>
+ *
+ * <p>The helper implements a key event handler. If you pass a
+ * {@link android.support.v17.leanback.app.PlaybackOverlaySupportFragment} the fragment's input event
+ * handler will be set. Otherwise, you should set the glue object as key event handler to the
+ * ViewHolder when bound by your row presenter; see
+ * {@link RowPresenter.ViewHolder#setOnKeyListener(android.view.View.OnKeyListener)}.
+ * </p>
+ *
+ * <p>To update the controls row progress during playback, override {@link #enableProgressUpdating}
+ * to manage the lifecycle of a periodic callback to {@link #updateProgress()}.
+ * {@link #getUpdatePeriod()} provides a recommended update period.
+ * </p>
+ *
