Recent update from Developer Android com  Don t work with MAC addresses MAC addresses are globally unique  not user-resettable  and survive factory resets  For these reasons  it s generally not recommended to use MAC address for any form of user identification  Devices running Android 10  API level 29  and higher report randomized MAC addresses to all apps that aren t device owner apps  Between Android 6 0  API level 23  and Android 9  API level 28   local device MAC addresses  such as Wi-Fi and Bluetooth  aren t available via third-party APIs  The WifiInfo getMacAddress   method and the BluetoothAdapter getDefaultAdapter   getAddress   method both return 02 00 00 00 00 00  Additionally  between Android 6 0 and Android 9  you must hold the following permissions to access MAC addresses of nearby external devices available via Bluetooth and Wi-Fi scans  Method Property   Permissions Required ACCESS FINE LOCATION or ACCESS COARSE LOCATION  Source  https   developer android com training articles user-data-ids html version specific details identifiers in m

WifiManager wifiManager    WifiManager  getApplicationContext   getSystemService Context WIFI SERVICE   WifiInfo wInfo   wifiManager getConnectionInfo    String macAddress   wInfo getMacAddress      Also  add below permission in your manifest file  lt uses-permission android name  quot android permission ACCESS WIFI STATE quot   gt   Please refer to Android 6 0 Changes   To provide users with greater data protection  starting in this release  Android removes programmatic access to the device   s local hardware identifier for apps using the Wi-Fi and Bluetooth APIs  The WifiInfo getMacAddress   and the BluetoothAdapter getAddress   methods now return a constant value of 02 00 00 00 00 00  To access the hardware identifiers of nearby external devices via Bluetooth and Wi-Fi scans  your app must now have the ACCESS FINE LOCATION or ACCESS COARSE LOCATION permissions

With this code you will be also able to get MacAddress in Android 6 0 also  public static String getMacAddr         try           List  lt NetworkInterface gt  all   Collections list NetworkInterface getNetworkInterfaces             for  NetworkInterface nif  all                if   nif getName   equalsIgnoreCase  wlan0    continue               byte   macBytes   nif getHardwareAddress                if  macBytes    null                    return                                StringBuilder res1   new StringBuilder                for  byte b  macBytes                      res1 append Integer toHexString b  amp  0xFF                          res1 append String format   02X    b                               if  res1 length    gt  0                    res1 deleteCharAt res1 length   - 1                             return res1 toString                    catch  Exception ex         return  02 00 00 00 00 00       EDIT 1  This answer got a bug where a byte that in hex form got a single digit  will not appear with a  0  before it  The append to res1 has been changed to take care of it
