Monitoring multiple regions using beacons

BLE Beacons
1

Hello there , I would need some help regarding monitoring.
I am developing an application in which I want to define multiple regions and show a particular notification depending in which region the user is .
I want to know how I am able to do this .
From what I know I should start monitoring all the regions I want using the Beacon Manager, but I want to know how I am able to make the Monitoring Listener to know what to display on the entered region depending on the region I am . Below I have my code. Thank you in advance.

private BeaconManager beaconManager;

@Override
public void onCreate(Bundle icicle)
{
   final  Region region1 = new Region(
            "monitored region",
            UUID.fromString("B9407F30-F5F8-466E-AFF9-25556B57FE6D"),
            22504, 44827);
    final  Region region2 = new Region(
            "monitored region",
            UUID.fromString("B9407F30-F5F8-466E-AFF9-25556B57FE6D"),
            22544, 48427);
    final  Region region3 = new Region(
            "monitored region",
            UUID.fromString("B9407F30-F5F8-466E-AFF9-25556B57FE6D"),
            2254, 48327);
    super.onCreate(icicle);
    beaconManager = new BeaconManager(getApplicationContext());
    beaconManager.connect(new BeaconManager.ServiceReadyCallback() {
        @Override
        public void onServiceReady() {
            beaconManager.startMonitoring(region1);
            beaconManager.startMonitoring(region2);
            beaconManager.startMonitoring(region3);

        }
    });

    beaconManager.setMonitoringListener(new BeaconManager.MonitoringListener() {
        @Override
        public void onEnteredRegion(Region region, List<Beacon> list) {
           shownotification();

        }

        @Override
        public void onExitedRegion(Region region) {

        }
    });

First, assign different identifiers to all your regions:

final  Region region1 = new Region(
"beacon 1", // <=============================
UUID.fromString("B9407F30-F5F8-466E-AFF9-25556B57FE6D"),
22504, 44827);
final  Region region2 = new Region(
"beacon 2", // <=============================
UUID.fromString("B9407F30-F5F8-466E-AFF9-25556B57FE6D"),
22544, 48427);
final  Region region3 = new Region(
"beacon 3", // <=============================
UUID.fromString("B9407F30-F5F8-466E-AFF9-25556B57FE6D"),
2254, 48327);

Then in your onEntered/onExited, you can simple check the region’s identifier:

@Override
public void onEnteredRegion(Region region, List<Beacon> list) {
    if (region.getIdentifier().equals("beacon 1")) {
        // do something
    } else if // ...
}

Hello,
I try this code it is working , but it is very slow means it is not responding as I enter in region and second when app is in back ground not receiving message on onEnteredRegion or exit region.
can you please share how can I achieve this.
