我正在为一个项目使用 Android IBeacon 库。我需要创建一个在后台开始对信标进行测距的服务，并在找到一个（最近的一个）时通知用户。我已经根据我找到的许多示例进行了很多搜索并进行了编码，但它仍然不起作用。使用日志我发现 IBeaconManager 没有绑​​定，所以 onIBeaconServiceConnect 永远不会被调用。我已经尝试了一些我在这里找到的解决方案，但没有一个有用。如果有人可以帮助我解决这个问题，我将不胜感激。我在这里发布了一些代码

公共类 RangingService 扩展服务实现 IBeaconConsumer
{

    私人 IBeaconManager 信标管理器；


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

    beaconManager = IBeaconManager.getInstanceForApplication(this);
    Log.d("RangingService","Created beaconManager instance");
    beaconManager.setBackgroundBetweenScanPeriod(120000);
    beaconManager.setBackgroundScanPeriod(30000);
    beaconManager.bind(this);

    if(beaconManager.isBound(this))
    {
        Log.d("RangingService","Beacon manager bound");
    }
    else
    {
        Log.d("RangingService","Beacon manager not bound");
    }

    //Show the service has started
    notify("RangingService created", "RangingService has started");
}

@Override
public void onDestroy()
{
    super.onDestroy();
    beaconManager.unBind(this);
}


@Override
public void onIBeaconServiceConnect() 
{
    Log.d("RangingService", "Entering onIBeaconServiceConnect");

    beaconManager.setRangeNotifier(new RangeNotifier() {

        @Override
        public void didRangeBeaconsInRegion(Collection<IBeacon> beacons, Region region)
        {
            if(beacons.size() > 0)
            {
                IBeacon nearestBeacon = beacons.iterator().next();

                for(IBeacon b : beacons)
                {
                    if(nearestBeacon.getProximity() == IBeacon.PROXIMITY_UNKNOWN)
                    {
                        nearestBeacon = b;
                    }
                    else
                    {
                        if(b.getProximity() != IBeacon.PROXIMITY_UNKNOWN)
                        {
                            if(b.getAccuracy() < nearestBeacon.getAccuracy())
                            {
                                nearestBeacon = b;
                            }
                        }
                    }
                }

                Log.d("RangingService","Nearest Beacon Found "+nearestBeacon.getMajor()+";"+nearestBeacon.getMinor());
                notify("Beacon read","Major: "+nearestBeacon.getMajor()+"; Minor: "+nearestBeacon.getMinor());

            }
            else
            {
                Log.d("RangingService","No beacons");
            }
        }
    });

    try
    {
        Log.d("RangingService", "Entering startRangingBeacons");
        beaconManager.startRangingBeaconsInRegion(new Region("myRangingUniqueId", null, null, null));
    }
    catch(RemoteException e)
    {
        notificar("Error", e.getMessage());
        Log.e("RangingService", "Error while starting scanning: "+e.getMessage());
    }
}

@Override
public IBinder onBind(Intent intent) {
    // TODO Auto-generated method stub
    Log.d("RangingService", "Entering onBind");
    return null;
}

该服务也已经在我的清单中。谢谢你的帮助。

几点：

  1. The code indicates you are using a 0.x version of the Android iBeacon Library. If you are starting a new project, I would strongly recommend you use the Android Beacon Library 2.0, as the earlier library is no longer actively maintained, and it is now hard to find documentation for it.

  2. Regardless of the library version you are using, you should be able to get a callback to the onBeaconServiceConnect() method after you bind to the BeaconManager. The fact that you don't get this callback probably indicates that the BeaconService is not starting up properly.

The most likely reason that the BeaconService is not starting up properly is because it is not properly declared in the manifest. If you are using Eclipse, you must edit your project.properties file and add the line: manifestmerger.enabled=true. If you are using AndroidStudio, this is not necessary. If you are using IntelliJ, you may have to declare the service manually.

You can verify if the manifest has the proper entries by looking at the generated manifest file in bin/AndroidManifest.xml, and verifying it has an entry for the BeaconService.

I had faced similar issues. Got resolved by doing following things

  1. In eclipse project.properties added manifestmerger.enabled=true

  2. restarted the eclipse

  3. uninstalled other beacon apps in my android phone and restarted the phone
