Proximity value getting null and accuracy value getting -1 every time I run my app

[amithkumarsingh]

private BCBeaconManager mBeaconManager;

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

    mServiceContext = BlueCatsSDKInterfaceService.this;

    mBeaconManager = new BCBeaconManager();
    mBeaconManager.registerCallback(mBeaconManagerCallback);

    Log.d(TAG, "onCreate");
}

@Override
public int onStartCommand(final Intent intent, final int flags, final int startId) {
    Log.d(TAG, "onStartCommand");

    super.onStartCommand(intent, flags, startId);

    String appToken = "";
    if (intent != null && intent.getStringExtra(BlueCatsSDK.EXTRA_APP_TOKEN) != null) {
        appToken = intent.getStringExtra(BlueCatsSDK.EXTRA_APP_TOKEN);
    }

    // add any options here
    Map<String, String> options = new HashMap<String, String>();
         BlueCatsSDK.setOptions(options);
    BlueCatsSDK.startPurringWithAppToken(getApplicationContext(), appToken);
    Log.d(TAG, "startPurringWithAppToken " + appToken);

    // start the service and keep running even if activity is destroyed

    return START_STICKY;
}

@Override
public void onDestroy() {
    Log.d(TAG, "onDestroy");

    super.onDestroy();
}

   private BCBeaconManagerCallback mBeaconManagerCallback = new BCBeaconManagerCallback() {
    
    @Override
    public void didEnterBeacons(List<BCBeacon> beacons) {
        Log.d(TAG, "didEnterBeacons");
        super.didEnterBeacons(beacons);
    }

    @Override
    public void didExitBeacons(List<BCBeacon> beacons) {
        Log.d(TAG, "didExitBeacons");
        super.didExitBeacons(beacons);
    }

    @Override
    public void didRangeBeacons(List<BCBeacon> beacons) {
        Log.d(TAG, "didRangeBeacons");
        super.didRangeBeacons(beacons);
    }

};

The didEnterBeacon() and didExitBeacon() method calback are getting called by didRangeBeacon() method is not getting called.

Also checking the deatils of deacon in didEnterBeacon() the proximity value is getting null and accuracy is getting -1 every time when I are the app

Note : I am testing the app by using other beacon transmitter app by replacing the ProximityUUID with available ProximityUUID in Bluecats portal not with Real Beacon device

Help me with this.
