        }

请检查这个代码…使用此代码。我们将从移动互联网获得IP…

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()) {
                        return inetAddress.getHostAddress().toString();
                    }
                }
            }

如果你有一个壳;Ifconfig eth0也适用于x86设备

您不需要像目前提供的解决方案那样添加权限。以字符串形式下载此网站:

or

http://www.telize.com/geoip

下载一个网站作为字符串可以用java代码完成:

像这样解析JSON对象:

json属性“query”或“ip”包含ip地址。
