Get Android WiFi “net.hostname” from code

Question

When an Android device connects to a wifi AP, it identifies itself with a name like:

android_cc1dec12345e6054

How can that string be obtained from within an Andr

Answer 1

I used jiangze ren's answer and modified it.

Now you can get hostname by getting IP address of device:

   WifiManager wm = (WifiManager) getApplicationContext().getSystemService(WIFI_SERVICE);
                        final String ip = Formatter.formatIpAddress(wm.getConnectionInfo().getIpAddress());
                        InetAddress address = InetAddress.getByName(ip);
                        System.out.println(address.getHostName());  // <-- host name is here and not localhost!
