onBeaconServiceConnect не вызывается

Если вы реализуете интерфейс BeaconConsumer в экземпляре Fragment (а не в экземпляре Activity, Service или Application), вам необходимо объединить все методы в цепочку. Как это:

@Override
public Context getApplicationContext() {
    return getActivity().getApplicationContext();
}

@Override
public void unbindService(ServiceConnection serviceConnection) {
    getActivity().unbindService(serviceConnection);
}

@Override
public boolean bindService(Intent intent, ServiceConnection serviceConnection, int i) {
    return getActivity().bindService(intent, serviceConnection, i);
}

Я не уверен. Через несколько дней этот код маяка работает для меня. Пожалуйста, проверьте. Если возникнут какие-либо проблемы, я отправлю весь свой код.

Попробуй это:

 beaconManager.startRangingBeaconsInRegion(new Region("myBeaons", Identifier.parse(UUID), null, null));

вместо этой строки в вашем коде.

beaconManager.startRangingBeaconsInRegion(
                new Region(Constant.UUID, null, null, null));

этот код работает для меня. Пожалуйста, попробуйте этот код:

Создать класс приложения:

public class BeaconReferenceApplication extends Application implements BootstrapNotifier {
    private BackgroundPowerSaver backgroundPowerSaver;
    private boolean haveDetectedBeaconsSinceBoot = false;
    private MonitoringActivity monitoringActivity = null;
    private String UUID = "23542266-18D1-4FE4-B4A1-23F8195B9D39";


    private static final String TAG = ".MyApplicationName";
    private RegionBootstrap regionBootstrap;

    @Override
    public void onCreate() {
        super.onCreate();
        Log.d(TAG, "App started up");
        BeaconManager beaconManager = BeaconManager.getInstanceForApplication(this);
        // To detect proprietary beacons, you must add a line like below corresponding to your beacon
        // type.  Do a web search for "setBeaconLayout" to get the proper expression.
        // beaconManager.getBeaconParsers().add(new BeaconParser().
        //        setBeaconLayout("m:2-3=beac,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25"));

        // wake up the app when any beacon is seen (you can specify specific id filers in the parameters below)
        Region region = new Region("com.example.myapp.boostrapRegion", null, null, null);
        regionBootstrap = new RegionBootstrap(this, region);
    }

    @Override
    public void didDetermineStateForRegion(int arg0, Region arg1) {
        // Don't care
    }

    @Override
    public void didEnterRegion(Region arg0) {
        Log.d(TAG, "Got a didEnterRegion call");
        // This call to disable will make it so the activity below only gets launched the first time a beacon is seen (until the next time the app is launched)
        // if you want the Activity to launch every single time beacons come into view, remove this call.
        regionBootstrap.disable();
        Intent intent = new Intent(this, MainActivity.class);
        // IMPORTANT: in the AndroidManifest.xml definition of this activity, you must set android:launchMode="singleInstance" or you will get two instances
        // created when a user launches the activity manually and it gets launched from here.
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        this.startActivity(intent);
    }

    @Override
    public void didExitRegion(Region arg0) {
        // Don't care
    }
}

Класс активности

public class MainActivity extends Activity implements BeaconConsumer {

    public static final String TAG = "BeaconsEverywhere";
    private BeaconManager beaconManager;
    private String UUID = "23542266-18D1-4FE4-B4A1-23F8195B9D39";

    @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,d:25-25"));

        beaconManager.bind(this);

    }

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

    @Override
    public void onBeaconServiceConnect() {
        final Region region = new Region("myBeaons", Identifier.parse(UUID), null, null);

        beaconManager.setMonitorNotifier(new MonitorNotifier() {
            @Override

                try {

                } catch (RemoteException e) {
                    e.printStackTrace();
                }
            }

            @Override

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

        try {

        } catch (RemoteException e) {

    }
