All beacons are not shown in Android using altBeacon library

Question

I am using the AltBEacon Android library for developing an iBeacon app for Android devices. I am scanning for beacons, however, only two out of four

Answer 1

OK, I finally solved it. I ordered according to the beacon MAC address. So instead of:

public void initAll(Collection newBeacons) {
    this.beacons.clear();
    this.beacons.addAll(newBeacons);
}

I did:

public void initAll(Collection newBeacons) {

    this.beacons.clear();
    this.beacons.addAll(newBeacons);

    //Sort
    Collections.sort(this.beacons, new Comparator() {
        @Override
        public int compare(Beacon b1, Beacon b2) {
            String mac1 = b1.getBluetoothAddress();
            String mac2 = b2.getBluetoothAddress();

            return mac1.compareTo(mac2);
        }
    });
}
