                String name, 
                int icon)

e.g. start a radio station based on the current item or skip ahead by 30 seconds.

Parameters
`action`	`String`: An identifier for this action. It can be sent back to the `MediaSession` through `MediaController.TransportControls#sendCustomAction(String, Bundle)`.
`name`	`String`: The display name for the action. If text is shown with the action or used for accessibility, this is what should be used.
`icon`	`int`: The resource action of the icon that should be displayed for the action. The resource should be in the package of the `MediaSession`.

`PlaybackState.Builder`	this

Set the current state of playback.

The position must be in ms and indicates the current playback position within the item. If the position is unknown use PlaybackState.PLAYBACK_POSITION_UNKNOWN. The update time will be set to the current SystemClock#elapsedRealtime().

The speed is a multiple of normal playback and should be 0 when paused and negative when rewinding. Normal playback speed is 1.0.

The state must be one of the following:

Parameters
`state`	`int`: The current state of playback. Value is `PlaybackState.STATE_NONE`, `PlaybackState.STATE_STOPPED`, `PlaybackState.STATE_PAUSED`, `PlaybackState.STATE_PLAYING`, `PlaybackState.STATE_FAST_FORWARDING`, `PlaybackState.STATE_REWINDING`, `PlaybackState.STATE_BUFFERING`, `PlaybackState.STATE_ERROR`, `PlaybackState.STATE_CONNECTING`, `PlaybackState.STATE_SKIPPING_TO_PREVIOUS`, `PlaybackState.STATE_SKIPPING_TO_NEXT`, `PlaybackState.STATE_SKIPPING_TO_QUEUE_ITEM`, or android.media.session.PlaybackState.STATE_PLAYBACK_SUPPRESSED
`position`	`long`: The position in the current item in ms.
`playbackSpeed`	`float`: The current speed of playback as a multiple of normal playback.

Returns

                long updateTime)

Set the current state of playback.

The position must be in ms and indicates the current playback position within the item. If the position is unknown use PlaybackState.PLAYBACK_POSITION_UNKNOWN. When not using an unknown position the time at which the position was updated must be provided. It is okay to use SystemClock#elapsedRealtime() if the current position was just retrieved.

The speed is a multiple of normal playback and should be 0 when paused and negative when rewinding. Normal playback speed is 1.0.

The state must be one of the following:

Parameters
`state`	`int`: The current state of playback.

`updateTime`	`long`: The time in the `SystemClock#elapsedRealtime` timebase that the position was updated at.
