Method

StringgetLocalAddr()
get Local Addr 
Enumeration<NetworkInterface> interfaces = null;
try {
    interfaces = NetworkInterface.getNetworkInterfaces();
    while (interfaces.hasMoreElements()) {
        NetworkInterface ifc = interfaces.nextElement();
        if (ifc.isLoopback() || ifc.isVirtual() || !ifc.isUp()) {

                return address.getHostAddress();
} catch (SocketException e) {
    e.printStackTrace();
    return null;

InetAddressgetLocalAddr()
Will try to find the local IP V4 address there is not the loopback address 
Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces();
while (interfaces.hasMoreElements()) {
    NetworkInterface dev = interfaces.nextElement();
    String devName = dev.getDisplayName();

        InetAddress addr = addresses.nextElement();
        if (addr instanceof Inet6Address)
...
StringgetLocalAddress()
This method returns the local IP address as a String. 
try {
