Altbeacon - Neither monitoring or ranging is working with no error

Question

My code is as follows (taken from here)

public class MainActivity extends ActionBarActivity implements ROXIMITYEngineListener, BeaconConsumer {
    private final String TAG = "MainActivity";

    private BeaconManager beaconManager;

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

        beaconManager = BeaconManager.getInstanceForApplication(this.getApplicationContext());
        beaconManager.bind(this);
    }

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

    @Override
    public void onBeaconServiceConnect() {
        Log.i(TAG, "onBeaconServiceConnect");

        beaconManager.setMonitorNotifier(new MonitorNotifier() {
            @Override
            public void didEnterRegion(Region region) {
                Log.i(TAG, "I just saw an beacon for the first time!");
                Toast.makeText(MainActivity.this, "I just saw an beacon for the first time!", Toast.LENGTH_LONG).show();
            }

            @Override
            public void didExitRegion(Region region) {
                Log.i(TAG, "I no longer see an beacon");
                Toast.makeText(MainActivity.this, "I no longer see an beacon", Toast.LENGTH_LONG).show();
            }

            @Override
            public void didDetermineStateForRegion(int state, Region region) {
                Log.i(TAG, "I have just switched from seeing/not seeing beacons: "+state);
                Toast.makeText(MainActivity.this, "I have just switched from seeing/not seeing beacons: "+state, Toast.LENGTH_LONG).show();
            }
        });

        beaconManager.setRangeNotifier(new RangeNotifier() {
            @Override
            public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) {
                if (beacons.size() > 0) {
                    Log.i(TAG, "The first beacon I see is about " + beacons.iterator().next().getDistance() + " meters away.");
                    Toast.makeText(MainActivity.this, "The first beacon I see is about " + beacons.iterator().next().getDistance() + " meters away.", Toast.LENGTH_LONG).show();
                }
            }
        });

        try {
            beaconManager.startMonitoringBeaconsInRegion(new Region("uniqueid1", null, null, null));
            beaconManager.startRangingBeaconsInRegion(new Region("uniqueid2", null, null, null));
        } catch (RemoteException e) {
            Log.e(TAG, "", e);
        }
    }
}

onBeaconServiceConnected was indeed called! But nothing else was called/ printed. No error was thrown.
What am I missing?

This app by the same people (Radius Networks) can detect my beacon so why can't my app do the same?

My phone is Nexus 5 running Android 5.1. I'm using the Android Beacon Library 2.1.4 and I'm using Android Studio version 1.2.1.1.
(I don't think it matters but my beacon is Roximity Model X)

I've also tried doing only monitoring but it doesn't either.

Interestingly, when I look at the logcat with no filter, I can see BtGatt doing the scan and detect the beacon:

Answer 1

My guess is that you are trying to detect a proprietary beacon (e.g. an iBeacon). Because the library is open source, it will not detect proprietary beacons by default because doing so would require us to publish the proprietary beacon format. That can cause legal problems.

The fix is easy. You just need to add one line of code to your onCreate method that sets the beacon parser needed for your proprietary beacon type.

Do a Google search for "getbeaconparsers" and you will see the line of code to add.

Answer 2

    private BeaconManager beaconManager;
    @Override
    protected void onCreate(Bundle savedInstanceState {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity);
        beaconManager = BeaconManager.getInstanceForApplication(this);
//layout of ibeacon        
beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"));
        ...
    }

Answer 3

Your monitoring and ranging region name should be same. Try this :

beaconManager.startMonitoringBeaconsInRegion(new Region("uniqueid1", null, null, null));
beaconManager.startRangingBeaconsInRegion(new Region("uniqueid1", null, null, null));
