How to handle the MAC address(physical address) of the roteadot?

Question

I am making an application on INTEL XDK for smartphone and would like to capture the value of MAC Adrees Wifi Router active at the moment, as well as the network name (SSID) and password, to make comparisons. Example: I have 3 routers with the same name and password, but with the VALUES OF MACS 'A', 'B' and 'C' respectively in my work and I want that when I am connected to the Router with MAC Adrees = 'B' the application enable some functions and inform me that I am connected to the Router with SSID = 'work', Password = 'password' and MAC = 'B'.
How to handle the MAC Adrees (physical address) of the router?

Oh, there’s this solution in Java :

import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;

public class App{

   public static void main(String[] args){

    InetAddress ip;
    try {

        ip = InetAddress.getLocalHost();
        System.out.println("Current IP address : " + ip.getHostAddress());

        NetworkInterface network = NetworkInterface.getByInetAddress(ip);

        byte[] mac = network.getHardwareAddress();

        System.out.print("Current MAC address : ");

        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < mac.length; i++) {
            sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));        
        }
        System.out.println(sb.toString());

    } catch (UnknownHostException e) {

        e.printStackTrace();

    } catch (SocketException e){

        e.printStackTrace();

    }

   }

}

See if it helps you.
