On beacon Detected ALT BEACON

Question

I can see a log in my consolse everytime a beacon is detected

D/BeaconService: beacon detected : id1: xxxxx-xxx-xxxxx-xxx-xxxxx id2: xxx id3: xx

But i could not figure out how to catch this function. Which interface is needed for get this function.

Thanks

Try this,

    // Y positions are relative to height of bg_distance image.
    Private static final double RELATIVE_START_POS = 320.0 / 1110.0;
    Private static final double RELATIVE_STOP_POS = 885.0 / 1110.0;

    Private BeaconManager beaconManager;
    Private Beacon beacon;
    Private Region region;
    Private View distance view, dotView;
    Private int startY = -1;
    Private int segmentLength = -1;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.distance_view);
        dotView = findViewById(R.id.distance_iv_dot);
        beacon = getIntent().getParcelableExtra(MainActivity.EXTRAS_BEACON);
        region = new Region("regionid", beacon.getProximityUUID(), beacon.getMajor(), beacon.getMinor());
        if (beacon == null) {
            Toast.makeText(this, "Beacon not found in intent extras", Toast.LENGTH_LONG).show();
            finish();
            return;
        }
        beaconManager = new BeaconManager(this);
        distanceview = findViewById(R.id.distance_background_view);
        distanceview.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {

                distanceview.getViewTreeObserver().removeOnGlobalLayoutListener(this);

                startY = (int) (RELATIVE_START_POS * distanceview.getMeasuredHeight());
                int stopY = (int) (RELATIVE_STOP_POS * distanceview.getMeasuredHeight());
                segmentLength = stopY - startY;

        double distance = Math.min(Utils.computeAccuracy(beacon), 6.0);
        return startY + (int) (segmentLength * (distance / 6.0));
    }

                        }
                        if (foundBeacon != null) {

I hope it will Help you that to get the function for detecting the Beaconlist.:)
