AltBeacon库问题

Question

我正在用AltBeacon开发一个安卓项目，在GitHub - https://github.com/justinodwyer/Beacon-Scanner-and-Logger中引用这段代码，但在eclipse中面临以下问题-

The BeaconManager is not bound to the service. Call beaconManager.bind(BeaconConsumer consumer) and wait for a callback to onBeaconServiceConnect()

我的代码如下。

BeaconScannerApp app = (BeaconScannerApp)this.getApplication();
beaconManager = app.getBeaconManager();
beaconManager.getBeaconParsers().add(new BeaconParser()
.setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"));
beaconManager.bind(this);
region = new Region("myRangingUniqueId", null, null, null);
beaconManager.setRangeNotifier(new RangeNotifier() {
        @Override 
        public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) {
        if (beacons.size() > 0) {
        Iterator <Beacon> beaconIterator = beacons.iterator();
        while (beaconIterator.hasNext()) {
        Beacon beacon = beaconIterator.next();
        logBeaconData(beacon);
        }
        }
        }
       });

       try {
           beaconManager.startRangingBeaconsInRegion(region);
       } catch (RemoteException e) {   
        Log.v("TEST", e.getMessage());
       }

所有来自信标的初始化都应该在OnBeaconServiceConnect()中进行，我在使用DidExitRegion()和DidEnterRegion()时遇到了麻烦，这正是因为我没有在OnBeaconServiceConnect()中初始化我的BeaconManager处理程序。你也可以，有时，做它的OnCreate，但对我来说是不工作的。它是C#，但它真的很相似。

下面是一个运行良好的示例：

public void OnBeaconServiceConnect()
    {

        beaconManager.SetForegroundScanPeriod(1000L);
        beaconManager.SetForegroundBetweenScanPeriod(10000L);

        rangeNotifier.DidRangeBeaconsInRegionComplete += RangeNotifier_DidRangeBeaconsInRegionComplete;
        monitorNotifier.EnterRegionComplete += MonitorNotifier_EnterRegionComplete;
        monitorNotifier.ExitRegionComplete += MonitorNotifier_ExitRegionComplete;

        beaconManager.SetRangeNotifier(rangeNotifier);
        beaconManager.SetMonitorNotifier(monitorNotifier);

        try
        {
            beaconManager.StartMonitoringBeaconsInRegion(region);
            beaconManager.StartRangingBeaconsInRegion(region);
        }catch(RemoteException e)
        {
            Log.Debug(TAG,e.ToString());
        }

    }
