Accessing Wifi settings from android (IPV4)

Question

I’m accessing the Wifi settings of Android, and is charging as if I’m searching for a standard IP IPV6. I wonder if there is any Wificonfiguration property to set to IPV4

Answer 1

To receive a IP patterned IPV4, use the following code:

public static String getIPV4 (){ 
    try {
        for (Enumeration enumeration = NetworkInterface.getNetworkInterfaces(); enumeration.hasMoreElements();){
            NetworkInterface nInterface = enumeration.nextElement();

            for (Enumeration IPenumeration = nInterface.getInetAddresses(); IPenumeration.hasMoreElements();){
            InetAddress netAdress = IPenumeration.nextElement();

            if (!netAdress.isLoopbackAddress()  &&  netAdress instanceof Inet4Address){ 
                    String IP4 = netAdress.getHostAddress().toString();
                    Toast.MakeText(getApplicationContext(), "IP: " + IP4, Toast.LENGTH_SHORT).show();
                    return IP4;
                }
            }
        }
    } catch (SocketException socketException) {
        Log.e("IP4 Erro", socketException.toString());
    }
    return null; 
}

To summarize all this, see:

• if(..., netAdress instanceof Inet4Address)

The above condition checks whether the item received in the netAdress is the type Inet4Adress. That was what you need. If you already used a code similar to this, just add the operator instanceof in its condition to compare the received elements to the standard IPV4.
