Android Question MAC Address

[Peter Yeung]

How to get the MAC Address of Android device.

Is it possible for an Android device to have MAC two Addresses? i.e. one for Wifi and one for mobile data?

Thanks!

This will return the wifi address.

You can change the Java code to:

#if JAVA
import java.net.NetworkInterface;
import java.util.Collections;
import java.util.List;
public static String getWifiMacAddress() {
  try {
  String interfaceName = "wlan0";
  List<NetworkInterface> interfaces = Collections.list(NetworkInterface.getNetworkInterfaces());
  for (NetworkInterface intf : interfaces) {
BA.Log("" + intf);
  byte[] mac = intf.getHardwareAddress();
  if (mac==null){
  continue;
  }

  StringBuilder buf = new StringBuilder();
  for (byte aMac : mac) {
  buf.append(String.format("%02X:", aMac));
  }
  if (buf.length()>0) {
  buf.deleteCharAt(buf.length() - 1);
  }
 
  BA.Log(buf.toString());
  }
  } catch (Exception ex) {
  ex.printStackTrace();
  }
  return "";
  }
#end if

This will print all the found addresses.
