如何使用 Exoplayer 的 PlayerNotificationManager 發送靜默前台通知

Question

我正在使用最新版本的 Exoplayer (2.16.1)。 我使用下面的代碼創建前台服務通知，但它帶有通知聲音。 我怎樣才能防止這種聲音？

 override fun onCreate() {
    super.onCreate()

    playerNotificationManager = PlayerNotificationManager
        .Builder(this, 9998, NOTIFICATION_CHANNEL_ID)
        .setMediaDescriptionAdapter(PlayerNotificationAdapter())
        .setChannelImportance(IMPORTANCE_HIGH)
        .setNotificationListener(object : PlayerNotificationManager.NotificationListener {
            override fun onNotificationPosted(
                notificationId: Int,
                notification: Notification,
                ongoing: Boolean
            ) {
                super.onNotificationPosted(notificationId, notification, ongoing)
                if (ongoing) {
                    startForeground(notificationId, notification)
                }
            }

            override fun onNotificationCancelled(
                notificationId: Int,
                dismissedByUser: Boolean
            ) {
                super.onNotificationCancelled(notificationId, dismissedByUser)
                stopSelf()
                stopForeground(false)
            }
        })
        .setChannelNameResourceId(R.string.NotificationChannelName)
        .setChannelDescriptionResourceId(R.string.NotificationChannelDescription)
        .build()

    playerNotificationManager.setSmallIcon(R.drawable.ic_play)
    playerNotificationManager.setPriority(PRIORITY_MAX)
    playerNotificationManager.setPlayer(musicPlayerManager.exoPlayer)

    mediaSessionCompat = MediaSessionCompat(this, MEDIA_SESSION_TAG)
    mediaSessionCompat.isActive = true
    playerNotificationManager.setMediaSessionToken(mediaSessionCompat.sessionToken)

    mediaSessionConnector = MediaSessionConnector(mediaSessionCompat)

    val timelineQueueNavigator = object : TimelineQueueNavigator(mediaSessionCompat) {
        override fun getMediaDescription(
            player: Player,
            windowIndex: Int
        ): MediaDescriptionCompat {
            return MediaDescriptionCompat.Builder().build()
        }
    }
    mediaSessionConnector.setQueueNavigator(timelineQueueNavigator)
    mediaSessionConnector.setPlayer(musicPlayerManager.exoPlayer)
}

請注意，我想使用 Exoplayer 的 PlayerNotificationManager 來創建通知。

Answer 1

您可以設置： playerNotificationManager.setPriority(PRIORITY_DEFAULT) 在這種情況下發出靜默通知

在通知管理器中發布和取消通知時，我看不到名稱 stopSelf 和 startForeground 的任何樂趣，而不是這個，我得到 startForegroundservice ()。

請分享 startForeground() 和 stopSelf() 的代碼
