I'm working on a simple beacon proximity app using AltBeacon library from here https://altbeacon.github.io/android-beacon-library/samples.html.

I am experimenting with the sample code provided on the above website, however, each time I run the app it only goes to addRangingNotifier() method. If it detected the beacon it would go log the beacon size.

private Region defaultRegion = null;

defaultRegion = new Region("BeaconIdentifier", Identifier.fromUuid(java.util.UUID.fromString(UUID)), null, null);

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() {

   beaconManager.addRangeNotifier(new RangeNotifier() {

      @Override

      public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) {

         if (beacons.size() > 0) {

            Log.d("MainInfo","Beacon List Size " + beacons.size());

         }else{

            Log.d("MainInfo","Beacon Empty");

         }

      }

   });

   try {

      beaconManager.startRangingBeaconsInRegion(defaultRegion);

   } catch (RemoteException e) {}

}

I can receive the beacon size around of me.
I test the two device(A : Samsung galaxy J510-Marshmellow/B: Samsung galaxy J7-Nougat), B scan the beacon and print Beacon List Size, but, A can't scan the beacon and print Beacon Empty.

So I test same Marshmellow device, but I can't find it.

Are there any codes that should be added depending on the operating system?

The most likely thing wrong is that the UUID specified does not match your beacon. Try replacing this code:

  Identifier.fromUuid(java.util.UUID.fromString(UUID))

With

  null

To match all beacons. If this fixes it, replace the UUID with the one you are out of the detected beacon.
