PiP에 원격 작업 추가

PiP 창에 컨트롤 (재생, 일시중지 등)을 추가하려면 추가하려는 각 컨트롤에 대해 RemoteAction를 만듭니다.

1. 브로드캐스트 컨트롤의 상수를 추가합니다.

   // Constant for broadcast receiver
   const val ACTION_BROADCAST_CONTROL = "broadcast_control"
   
   // Intent extras for broadcast controls from Picture-in-Picture mode.
   const val EXTRA_CONTROL_TYPE = "control_type"
   const val EXTRA_CONTROL_PLAY = 1
   const val EXTRA_CONTROL_PAUSE = 2

2. PiP 창의 컨트롤에 관한 RemoteActions 목록을 만듭니다.
3. 그런 다음 BroadcastReceiver를 추가하고 onReceive()를 재정의하여 각 버튼의 작업을 설정합니다. DisposableEffect를 사용하여 수신기와 원격 작업을 등록합니다. 플레이어가 폐기되면 수신기를 등록 취소합니다.

   @RequiresApi(Build.VERSION_CODES.O)
   @Composable
   fun PlayerBroadcastReceiver(player: Player?) {
       val isInPipMode = rememberIsInPipMode()
       if (!isInPipMode || player == null) {
           // Broadcast receiver is only used if app is in PiP mode and player is non null
           return
       }
       val context = LocalContext.current
   
       DisposableEffect(player) {
           val broadcastReceiver: BroadcastReceiver = object : BroadcastReceiver() {
               override fun onReceive(context: Context?, intent: Intent?) {
                   if ((intent == null) || (intent.action != ACTION_BROADCAST_CONTROL)) {
                       return
                   }
   
                   when (intent.getIntExtra(EXTRA_CONTROL_TYPE, 0)) {
                       EXTRA_CONTROL_PAUSE -> player.pause()
                       EXTRA_CONTROL_PLAY -> player.play()
                   }
               }
           }
           ContextCompat.registerReceiver(
               context,
               broadcastReceiver,
               IntentFilter(ACTION_BROADCAST_CONTROL),
               ContextCompat.RECEIVER_NOT_EXPORTED
           )
           onDispose {
               context.unregisterReceiver(broadcastReceiver)
           }
       }
   }

4. 원격 작업 목록을 PictureInPictureParams.Builder에 전달합니다.

   val context = LocalContext.current
   
   val pipModifier = modifier.onGloballyPositioned { layoutCoordinates ->
       val builder = PictureInPictureParams.Builder()
       builder.setActions(
           listOfRemoteActions()
       )
   
       if (shouldEnterPipMode && player != null && player.videoSize != VideoSize.UNKNOWN) {
           val sourceRect = layoutCoordinates.boundsInWindow().toAndroidRectF().toRect()
           builder.setSourceRectHint(sourceRect)
           builder.setAspectRatio(
               Rational(player.videoSize.width, player.videoSize.height)
           )
       }
   
       if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
           builder.setAutoEnterEnabled(shouldEnterPipMode)
       }
       context.findActivity().setPictureInPictureParams(builder.build())
   }
   VideoPlayer(modifier = pipModifier)
