Beacon Android didEnterRegion未调用

Question

我买了以下Beacon（Link）。

我经历了这个tutorial并最终结束了这样：

public class MainActivity extends Activity implements BeaconConsumer {

    private BeaconManager beaconManager;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        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"));
        beaconManager.bind(this);
    }

    @Override
    public void onBeaconServiceConnect() {
        Log.d(TAG, "connectedService");
        beaconManager.addMonitorNotifier(new MonitorNotifier() {
            @Override
            public void didEnterRegion(Region region) {
                try {
                    Log.d("beaconTest", "didENTERRegion");
                    beaconManager.startRangingBeaconsInRegion(region);
                } catch (RemoteException e) {
                    e.printStackTrace();
                }
            }

            @Override
            public void didExitRegion(Region region) {
                try {
                    Log.d("beaconTest", "didEXITRegion");
                    beaconManager.stopRangingBeaconsInRegion(region);
                } catch (RemoteException e) {
                    e.printStackTrace();
                }
            }

            @Override
            public void didDetermineStateForRegion(int i, Region region) {

            }
        });

        beaconManager.addRangeNotifier(new RangeNotifier() {
            @Override
            public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) {
                for (Beacon beacon : beacons){
                    Log.d("beaconTest", "distance: " +
                            beacon.getDistance() + "id: " +
                            beacon.getId1() + "/" +
                            beacon.getId2() + "/" +
                            beacon.getId3());
                }
            }
        });

        try {
            beaconManager.startMonitoringBeaconsInRegion(new Region("", null, null, null));
        } catch (RemoteException e) {
            e.printStackTrace();
        }

    }
    @Override
    protected void onDestroy() {
        super.onDestroy();
        beaconManager.unbind(this);
    }

}

我的问题是，从未调用过didEnterRegion（）方法，我无法弄清楚原因。最小的SDK版本设置为18，我在手机上激活了蓝牙并请求了应用程序的许可。我可以找到第三方应用程序的灯塔，但不能找到我的代码。有人能告诉我我能做些什么来解决这个问题吗？

这是我的调试输出：
