循环中的BootstrapNotifier回调

我的信标检测有问题 .

有时应用程序循环遍历BootstrapNotifier回调（didDetermineStateForRegion（int arg0，Region arg1），didEnterRegion（Region arg0）和didExitRegion（Region arg0）） .

有时会在我启动应用程序时发生，其他时候是应用程序处于后台时...我没有找到任何模式，因此我不知道问题出在哪里 .

循环就像这样（只有一块日志）：

为什么会这样？该应用程序检测到该区域，但不会立即启动信标扫描 . 在这个循环或多或少一分钟之后，扫描通常开始（但不总是） .

为了测试应用程序，我使用这个信标软件模拟器作为 Launcher （https://github.com/WebBluetoothCG/ble-test-peripheral-android）

我的代码：

public class BeaconApplication extends Application implements BootstrapNotifier, BeaconConsumer {

    private String TAG = "MyApplication";
    private BeaconManager beaconManager;
    private Region region;


    @Override
    public void onCreate() {
        super.onCreate();
        startBeaconScan();
    }

    public void startBeaconScan() {

        Log.d(TAG, "App started up");

        beaconManager = BeaconManager.getInstanceForApplication(this);
        beaconManager.getBeaconParsers().add(new BeaconParser().
        setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25"));  //iBeacon layout

        beaconManager.setRegionStatePeristenceEnabled(false);
        beaconManager.bind(this);

        region = new Region("myMonitoringUniqueId", Identifier.parse("2f234454-cf6d-4a0f-adf2-f4911ba9ffa6"), null, null);
        new RegionBootstrap(this, region);
    }

    @Override
    public void didDetermineStateForRegion(int arg0, Region arg1) {
        beaconManager.addRangeNotifier(new RangeNotifier() {
            @Override
            public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) {
               //CODE FOR BEACON DETECTION    
            }
        });

        try {
            beaconManager.startRangingBeaconsInRegion(region);
        } catch (RemoteException e) {
            e.printStackTrace();
        }
        Log.d(TAG, "Got a didDetermineStateForRegion call: " + arg1.getId1());
    }

    @Override
    public void didEnterRegion(Region arg0) {
        Log.d(TAG, "Got a didEnterRegion call: " + arg0.getId1());
    }

    @Override
    public void didExitRegion(Region arg0) {
        Log.d(TAG, "Got a didExitRegion call: " + arg0.getBluetoothAddress());
    }

    @Override
    public void onBeaconServiceConnect() {
        try {
            beaconManager.setBackgroundBetweenScanPeriod(500);
            beaconManager.setBackgroundScanPeriod(500);
            beaconManager.setForegroundBetweenScanPeriod(500);
            beaconManager.setForegroundScanPeriod(500);
            beaconManager.updateScanPeriods();
        } catch (RemoteException e) {
            e.printStackTrace();
        }
    }
}

我试过“beaconManager.startRangingBeaconsInRegion（region）;”在“onBeaconServiceConnect（）”回调中，但似乎它没有产生任何差异 .
