I am using altbeacon for android and i cant't detect my beacon. I have tried https://github.com/AltBeacon/android-beacon-library-reference sample code also but can't detect beacon. Here is my code:
public class BeaconApplication extends Application implements BootstrapNotifier {
private Region region;
private RegionBootstrap regionBootstrap;
private BeaconManager beaconManager;
@Override
public void onCreate() {
super.onCreate();
beaconManager = BeaconManager.getInstanceForApplication(this);
beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("m:2-3=beac,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25"));
beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"));
beaconManager.setBackgroundScanPeriod(5000);
beaconManager.setBackgroundBetweenScanPeriod(10000);
region = new Region("backgroundRegion",
Identifier.parse("EBEFD083-70A2-47C8-9837-E7B5634DF524"), null, null);
regionBootstrap = new RegionBootstrap(this, region);
Log.i("selfBeacon", "Bootstrap created");
}
@Override
public void didEnterRegion(Region region) {
Log.i("selfBeacon", "Bootstrap didEnterRegion");
regionBootstrap.disable();
Intent intent = new Intent(this, SelfBeaconService.class);
if (Build.VERSION.SDK_INT >= 26) {

} else {

}

}
