我的信标在 didRangeBeaconsInRegion 上几秒钟后消失，但我靠近我的信标

Question

注意: 我检查了多个设备仍然没有改善，我将我的信标频率设置为 2000 毫秒，但仍然面临这个问题

我遇到了一个问题，信标检测稳定了几秒钟，但之后它消失了，然后它检测到了信标。我对这个建议很感兴趣，感谢代码示例！！

代码

    this.beaconManager = BeaconManager.getInstanceForApplication(this);
    beaconManager.setForegroundScanPeriod(500);
    beaconManager.setForegroundBetweenScanPeriod(500);
    enableBackgroundMode(true);
    beaconManager.setAndroidLScanningDisabled(true);
    this.beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"));
    this.beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout(EDDYSTONE_UID_LAYOUT));
    this.beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout(EDDYSTONE_URL_LAYOUT));
    this.beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout(EDDYSTONE_TLM_LAYOUT));
    this.beaconManager.setDebug(true);
    this.beaconManager.bind(this);




   this.beaconManager.addRangeNotifier(new RangeNotifier() {
        @Override
        public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) {
            Log.e(TAG, "beacons size=>" + beacons.size());

            if (beacons.size() > 0) {
               //my code 
             }
  }
 });

Answer 1

尝试删除以下行：

beaconManager.setForegroundScanPeriod(500);
beaconManager.setForegroundBetweenScanPeriod(500);

如果没有这些行（使用默认设置），库将在前台不断扫描。有了这些线，它一次只会扫描半秒，这很可能会错过您的信标的传输并导致检测丢失。
