I am using altbeacon library 2.15+ but for oreo and nougat version is not scanning beacon?

Question

onBeacon ServiceConnect method is to detect the beacon. For lollipop version is detecting for nougat and oreo version beacon not detecting: public void onBeaconServiceConnect() {

    RangeNotifier rangeNotifier = new RangeNotifier() {
        @Override
        public void didRangeBeaconsInRegion(Collection<Beacon> beacons, org.altbeacon.beacon.Region region) {
            Log.d(TAG, "in didRangeBeaconsInRegion " + beacons.size());
            if (beacons.size() > 0) {
                Log.d(TAG, "didRangeBeaconsInRegion called with beacon count:  " + beacons.size());
                for (Iterator<Beacon> iterator = beacons.iterator();
                     iterator.hasNext(); ) {
                    Beacon beacon = iterator.next();

                    if (beaconlist.size() > 0) {
                        Log.d(TAG, "List Size :" + beaconlist.size());
                        for (int i = 0; i < beaconlist.size(); i++) {
                            Log.d("BeaconList ", beaconlist.get(i));
                        }
                    }

                    if (!beaconlist.contains(beacon.getId1().toString())) {
                        Log.d(TAG,"In get APi");
                        getApi(beacon.getId1().toString());
                        beaconlist.add(beacon.getId1().toString());
                        Log.d(TAG, "Notify in dead state");
                        Log.d("Notify in dead state", beacon.getId1().toString());
                    }
                }
            }
        }
    };
    try {
        Log.d(TAG, "I am in startRangingBeaconsInRegion");
        beaconManager.startRangingBeaconsInRegion(new Region("myRangingUniqueId", null, null, null));
        beaconManager.addRangeNotifier(rangeNotifier);
    } catch (RemoteException e) {
        e.printStackTrace();
    }
}

This is my code can any one give solution for this issue.

Two things to check:

Have you added COARSE_LOCATION permission to your AndroidManifest.xml and added code to successfully obtain that permission from the user dynamically at runtime?
Do you successfully construct a BeaconManager, call bind(...) and verify you get a callback to onBeaconServiceConnect() before starting ranging? If you do not, you will get a RemoteException when you try to start ranging. It is a good idea to log this exception to LogCat with Log.e(TAG, "Not bound to beacon scanning service")
