Android altbeacon在后台运行时间隔不等

我正在开发一个运行后台服务以间隔设置蓝牙信标的应用程序.

我使用计时器启动Foregroundservice,以每分钟10秒的间隔(范围为200毫秒)启动信标,并计算最强的信标并将其提交给后端API.

只要应用程序处于前台状态,并且在屏幕关闭时,只要我使用adb logcat进行连接,它就可以正常工作.一旦我将其取下,就不再有任何内容提交到服务器,这意味着不再有任何信标被调整.

以下是相关的@L_616_5@段,希望我不要简化太多：

class Beaconservice : service(),BeaconConsumer {
    private var beaconManager: BeaconManager? = null
    private var rangingTimer = Timer("rangingTimer",truE)
    private val region = Region("com.beacon.test",Identifier.parse("f7826da6-4fa2-4e98-8024-bc5b71e0893e"),null,null)

    override fun onStartCommand(intent: Intent?,flags: Int,startId: int): Int {
        return service.START_STICKY
    }

    override fun onCreate() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODEs.O) {
            val notificationmanager = Mynotificationmanager.geTinstance()
            val notification = notificationmanager.buildBeaconserviceNotification(this,"iBeacon service",null)
            startForeground(NOTIFICATION_ID,notification)
        }

        initBeaconManager()
    }

    private fun initBeaconManager() {
        BeaconManager.setDebug(true)
        beaconManager = BeaconManager.geTinstanceForApplication(this)
        beaconManager?.foregroundScanPeriod = 200L
        beaconManager?.beaconParsers?.add(BeaconParser().setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"))
        beaconManager?.bind(this)
    }

    override fun onBeaconserviceConnect() {
        beaconManager?.addRangeNotifier { beacons,_ ->
            if (beacons.isnotEmpty()) {
                //code add ranged beacons to list
            }
        }
        startRanging()
    }

    private fun startRanging() {

        //code to reset the list of ranged beacons

        beaconManager?.startRangingBeaconsInRegion(region)

        rangingTimer.schedule(10000L) {
            stopRanging(50000L)
        }

    }

    private fun stopRanging(restartRangingAfter: Long? = null) {
        beaconManager?.stopRangingBeaconsInRegion(region)

        //code calcuate the strongest beacon and submit to server

        if (restartRangingAfter != null) {
            rangingTimer.schedule(restartRangingAfter) {
                startRanging()
            }
        }
    }
}
