通知立即消失

Question

这是前台服务启动时运行的代码。

val serviceChannel = NotificationChannel( CHANNEL_ID,
                                "SC noti", // 채널표시명
                                NotificationManager.IMPORTANCE_MIN)
serviceChannel.setShowBadge(false)

val fallChannel = NotificationChannel( FALL_CHANNEL_ID, "SC fall noti", NotificationManager.IMPORTANCE_HIGH)
val notificationSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
val audioAttributes = AudioAttributes.Builder().setContentType(AudioAttributes.CONTENT_TYPE_MUSIC).build()
fallChannel.enableVibration(true)
fallChannel.setSound(notificationSound, audioAttributes)
fallChannel.setShowBadge(true)

val notification: Notification = Notification.Builder(this, CHANNEL_ID)
            .setContentTitle(getText(R.string.notification_title))
            .setContentText(getText(R.string.notification_message))
            .setSmallIcon(R.drawable.ic_launcher_foreground)
            .setContentIntent(pendingIntent)
            .setTicker(getText(R.string.ticker_text))
            .build()

val manager = this.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
manager.createNotificationChannel(serviceChannel)
manager.createNotificationChannel(fallChannel)
startForeground(SC_NOTIFICATION_ID, notification)

这是在我的前台服务中满足特定条件时执行的代码。

(getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager).let{ notificationManager ->

    val builder: Notification.Builder = Notification.Builder(this@BLEService, FALL_CHANNEL_ID)
        .setContentTitle("낙상 감지")
        .setContentText("낙상이 감지되었습니다.")//취소 기능 추가해야함
        .setSmallIcon(R.drawable.ic_launcher_foreground)
        .setTicker(getText(R.string.ticker_text))

    notificationManager.notify(SC_FALL_NOTIFICATION_ID, builder.build())
}

由于前台服务应始终在“通道”中可见的限制，我们将该通道与通知通道分开。 serviceChannel 会正常收到通知（服务[=21=时显示，停止服务时消失）。但是当我用通知通知它时，fallChannel 消失得太快了。 0.1秒？它立即消失，无法检查。我将优先级设置为 HIGH，现在弹出一个弹出通知，我可以查看它，但它仍然比通知中心的光快，然后立即消失。无论是进入phone桌面还是锁屏状态都是一样的。通知一发布，它就消失了。它似乎由于某种未知原因被删除。有谁知道原因吗？

对于遇到与我相同问题的任何人。不知道为什么，在设置中打开“允许通知访问”的“辅助功能”就解决了。
