Human readable DhcpInfo.ipAddress?

Question

I am wondering how to get a human readable IP Adress from DhcpInfo.ipAddress? The tricky thing about it is, that it is an integer and obviously you can\'t store an IP address in

Answer 1

Use this function NetworkUtils.java \frameworks\base\core\java\android\net)

public static InetAddress intToInetAddress(int hostAddress) {
    byte[] addressBytes = { (byte)(0xff & hostAddress),
                            (byte)(0xff & (hostAddress >> 8)),
                            (byte)(0xff & (hostAddress >> 16)),
                            (byte)(0xff & (hostAddress >> 24)) };

    try {
       return InetAddress.getByAddress(addressBytes);
    } catch (UnknownHostException e) {
       throw new AssertionError();
    }
}
