If wifi of device is connected, I assume the device has an LAN IP address assigned presumably by a dhcp running on a router.
How can find it what's the LAN ip address (not the external ip) on the wifi interface ?
Thanks,
NetworkInterface will help you:
String ipAddress = null;
try {
for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
NetworkInterface intf = en.nextElement();
for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
InetAddress inetAddress = enumIpAddr.nextElement();
if (!inetAddress.isLoopbackAddress()) {
ipAddress = inetAddress.getHostAddress().toString();
}
}
}
} catch (SocketException ex) {}
