getting mobile network ip address

Question

hello i'm using this method to get mobile network IP address

public static String getMobileIPAddress() {
    try {
        List<NetworkInterface> interfaces = Collections.list(NetworkInterface.getNetworkInterfaces());
        for (NetworkInterface intf : interfaces) {
            List<InetAddress> addrs = Collections.list(intf.getInetAddresses());
            for (InetAddress addr : addrs) {
                if (!addr.isLoopbackAddress()) {
                    return  addr.getHostAddress();
                }
            }
        }
    } catch (Exception ex) { } // for now eat exceptions

    return "";
}

but the return value does not seems to be IP : fe80::dc19:94ff:fe6f:ae7b%dummy0

Actually your code is correct. It's getting list of InetAddresses where ip address also present with mac address. You have to use InetAddressUtils.isIPv4Address or addr instanceof Inet4Address (API >= 23) to filter ip address among them. Check below:

public static String getMobileIPAddress() {
    try {
        List<NetworkInterface> interfaces = Collections.list(NetworkInterface.getNetworkInterfaces());
        for (NetworkInterface intf : interfaces) {
            List<InetAddress> addrs = Collections.list(intf.getInetAddresses());
            for (InetAddress addr : addrs) {
                if (!addr.isLoopbackAddress() && 
                    addr instanceof Inet4Address) {
                    return  addr.getHostAddress();
                }
            }
        }
    } catch (Exception ex) { } // for now eat exceptions
    return "";
}

could you please share InetAddressUtils library gradle here! – Hesam Ilyaei Jan 26 '20 at 10:44
For API >= 23 refer to this https://stackoverflow.com/a/32178289/1950812 – fillobotto Jan 26 '20 at 10:49
Ow sorry, I forgot that it's deprecated use `addr instanceof Inet4Address` instead of that. Check my updated answer – Md. Asaduzzaman Jan 26 '20 at 10:49
