add this permission to your manifest file:

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

and use this:

WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE); WifiInfo wInfo = wifiManager.getConnectionInfo(); String macAddress = wInfo.getMacAddress();

I have solved this problem by using this

 private String deviceId() { return Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID); }
