提问by Shahtaj
When I am connected to WiFi, I can obtain the IP address of the Android phone.
当我连接到WiFi时，我可以获得Android手机的IP地址。
However, when on the mobile network like 3G connection, is it still possible to obtain the IP address of the Android phone?
If yes, kindly post the code for the same.

try something like this
尝试这样的事情
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) {}

the mobile device does not have an ip when browsing over 3G connection, You will get the ISP ip on the server side code. I recommend you replace the ip with the unique id, device type and coordinates if possible.
移动设备在通过 3G 连接浏览时没有 ip，您将在服务器端代码上获得 ISP ip。如果可能，我建议您将 ip 替换为唯一的 id、设备类型和坐标。
