Android的获取IP地址时，连接到蜂窝网络 [英] Getting IP address of Android when connected to Cellular Network

问题描述

有没有什么简单的办法，当通过移动数据网络连接到互联网来获取我的手机的IP地址。为了得到无线网络的IP地址，我使用下面这个简单的技术。

  WifiManager WM =（WifiManager）getSystemService（WIFI_SERVICE）;
串的ip = Formatter.formatIpAddress（wm.getConnectionInfo（）getIpAddress（））;
 

有什么办法类似于上面获得移动数据网络的IP地址。

我用下面的code，但它返回的MAC地址，WiFi和蜂窝网络的IP地址，但我感兴趣的只是在蜂窝IP地址。

 字符串ip地址= NULL;
                    尝试{
                        对于（枚举＆LT;＆NetworkInterface的GT; EN = NetworkInterface.getNetworkInterfaces（）; en.hasMoreElements（）;）{
                            NetworkInterface的INTF = en.nextElement（）;
                            为（枚举＆所述;为InetAddress＆GT; enumIpAddr = intf.getInetAddresses（）; enumIpAddr.hasMoreElements（））{
                                InetAddress类InetAddress类= enumIpAddr.nextElement（）;
                                如果（！inetAddress.isLoopbackAddress（））{
                                    ip地址= inetAddress.getHostAddress（）的toString（）。
                                    Log.i（Sarao5，ip地址）;
                                }
                            }
                        }
                    }赶上（SocketException前）{}
 

解决方案

低于code使用我在应用程序中使用 -

 公共静态字符串getDeviceIPAddress（布尔useIPv4）{
    尝试{
        清单＆LT;＆NetworkInterface的GT; networkInterfaces = Collections.list（NetworkInterface.getNetworkInterfaces（））;
        对于（的NetworkInterface的NetworkInterface：networkInterfaces）{
            清单＆LT;＆的InetAddress GT; inetAddresses = Collections.list（networkInterface.getInetAddresses（））;
            对于（InetAddress类InetAddress类：inetAddresses）{
                如果（！inetAddress.isLoopbackAddress（））{
                    。字符串SADDR = inetAddress.getHostAddress（）与toUpperCase（）;
                    布尔isIPv4 = InetAddressUtils.isIPv4Address（SADDR）;
                    如果（useIPv4）{
                        如果（isIPv4）
                            返回SADDR;
                    }其他{
                        如果（！isIPv4）{
                            //下降IP6端口后缀
                            INT DELIM = sAddr.indexOf（'％'）;
                            返回DELIM＆LT; 0？ SADDR：sAddr.substring（0，DELIM）;
                        }
                    }
                }
            }
        }
    }赶上（例外前）{
        ex.printStackTrace（）;
    }
    返回;
}
 

这是最简便的方法。

希望我的回答是有帮助的。

Is there any Simple Way to get the IP address Of my phone when connected to internet through mobile data Network. For getting WiFi IP address i am using following simple Technique.

 WifiManager wm = (WifiManager) getSystemService(WIFI_SERVICE);
String ip = Formatter.formatIpAddress(wm.getConnectionInfo().getIpAddress());

Is there any way similar to above to get IP address of mobile data network.

I have used following code but it returns MAC addresses ,IP addresses of both WiFi and cellular network but i am interested only in Cellular IP Address.

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();
                                    Log.i("Sarao5",ipAddress);
                                }
                            }
                        }
                    } catch (SocketException ex) {}

解决方案

Use below code as i use in my app -

public static String getDeviceIPAddress(boolean useIPv4) {
    try {
        List<NetworkInterface> networkInterfaces = Collections.list(NetworkInterface.getNetworkInterfaces());
        for (NetworkInterface networkInterface : networkInterfaces) {
            List<InetAddress> inetAddresses = Collections.list(networkInterface.getInetAddresses());
            for (InetAddress inetAddress : inetAddresses) {
                if (!inetAddress.isLoopbackAddress()) {
                    String sAddr = inetAddress.getHostAddress().toUpperCase();
                    boolean isIPv4 = InetAddressUtils.isIPv4Address(sAddr);
                    if (useIPv4) {
                        if (isIPv4)
                            return sAddr;
                    } else {
                        if (!isIPv4) {
                            // drop ip6 port suffix
                            int delim = sAddr.indexOf('%');
                            return delim < 0 ? sAddr : sAddr.substring(0, delim);
                        }
                    }
                }
            }
        }
    } catch (Exception ex) {
        ex.printStackTrace();
    }
    return "";
}

this is best and easy way.

Hope my answer is helpfull.
