在应用程序中创建自定义通知通道。

在Oreo设备上使用StartForegroundService启动服务。

startForeground(1, NotificationCompat.Builder(applicationContext, "my_channel_id")
            .setSmallIcon(R.drawable.some_icon)
            .setContentTitle("Title")
            .setContentText("AppName is running in the background for reason XYZ")
            .build())

在您的服务中，在onstartCommand()中创建通知并设置其优先级。不要忘记在清单中添加Android:enabled=“true”。

服务

override fun onStartCommand(intent: Intent, flags: Int, startId: Int): Int {
    super.onStartCommand(intent, flags, startId)

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            val channel = NotificationChannel(
                    ANDROID_CHANNEL_ID,
                    ANDROID_CHANNEL_NAME,
                    NotificationManager.IMPORTANCE_HIGH
            )

            notificationManager.createNotificationChannel(channel)
        }

        val notification = NotificationCompat.Builder(this, ANDROID_CHANNEL_ID)
                .setSmallIcon(R.drawable.ic_notification)
                .setContentTitle("Test title")
                .setContentText("Test content")
                .setPriority(NotificationCompat.PRIORITY_HIGH)
                .setAutoCancel(true)

        startForeground(1, notification.build())

        return Service.START_NOT_STICKY
}

Androidmanifest

<service android:name=".utils.AppService"
         android:enabled="true"/>
