Android 安卓推送在几秒钟后解散

我正在尝试创建传入呼叫推送通知。当发生呼叫事件时，前台服务将启动并发出通知。我为它和通知创建了一个通道。代码如下：

频道设置：

    private fun createCallChannelChannel(): NotificationChannel {
    val attributes = AudioAttributes.Builder()
        .setUsage(AudioAttributes.USAGE_NOTIFICATION)
        .build()
    val importance = NotificationManager.IMPORTANCE_HIGH
    return NotificationChannel(CALL_CHANNEL_ID, CALL_CHANNEL_NAME, importance).apply {
        description = CALL_CHANNEL_DESCRIPTION
        setSound(
            RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE),
            attributes
        )
        enableLights(true)
        enableVibration(true)
    }
}

    private fun buildIncomingCallNotification(payload: VoIpCallResponse): Notification {

    val remoteView = RemoteViews(packageName, R.layout.notification_call_view)
    remoteView.setOnClickPendingIntent(R.id.declineBtn, getDeclinePendingIntent())
    remoteView.setOnClickPendingIntent(R.id.acceptBtn, getAcceptPendingIntent(payload))
    return NotificationCompat.Builder(this, CALL_CHANNEL_ID)
        .setSmallIcon(R.mipmap.ic_launcher)
        .setPriority(NotificationCompat.PRIORITY_MAX)
        .setCategory(NotificationCompat.CATEGORY_CALL)
        .setStyle(NotificationCompat.DecoratedCustomViewStyle())
        .setCustomContentView(remoteView)
        .setAutoCancel(false)
        .build()
}

通知设置：

    private fun createCallChannelChannel(): NotificationChannel {
    val attributes = AudioAttributes.Builder()
        .setUsage(AudioAttributes.USAGE_NOTIFICATION)
        .build()
    val importance = NotificationManager.IMPORTANCE_HIGH
    return NotificationChannel(CALL_CHANNEL_ID, CALL_CHANNEL_NAME, importance).apply {
        description = CALL_CHANNEL_DESCRIPTION
        setSound(
            RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE),
            attributes
        )
        enableLights(true)
        enableVibration(true)
    }
}

    private fun buildIncomingCallNotification(payload: VoIpCallResponse): Notification {

    val remoteView = RemoteViews(packageName, R.layout.notification_call_view)
    remoteView.setOnClickPendingIntent(R.id.declineBtn, getDeclinePendingIntent())
    remoteView.setOnClickPendingIntent(R.id.acceptBtn, getAcceptPendingIntent(payload))
    return NotificationCompat.Builder(this, CALL_CHANNEL_ID)
        .setSmallIcon(R.mipmap.ic_launcher)
        .setPriority(NotificationCompat.PRIORITY_MAX)
        .setCategory(NotificationCompat.CATEGORY_CALL)
        .setStyle(NotificationCompat.DecoratedCustomViewStyle())
        .setCustomContentView(remoteView)
        .setAutoCancel(false)
        .build()
}

它起作用了。正在显示通知。但问题是通知会在几秒钟后最小化到通知栏。目标是在用户拒绝/接受呼叫或结束呼叫事件发生之前，防止通知最小化。比如WhatsApp。来电通知会无限期地显示在屏幕顶部。我怎样才能做同样的？我的频道的重要性是NotificationManager.importance\u HIGH，通知优先级是NotificationCompat.priority\u MAX

我找到了这个页面，它已经运行了

当然，使用foregroundService

val incomingCallNotification = notificationBuilder.build()
