android 获取设备真实ip地址

不多说 直接扔代码，android5，android9测试

public String getLocalIpAddress() {
        try {
            for (Enumeration en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
                NetworkInterface intf = en.nextElement();
                for (Enumeration enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
                    InetAddress inetAddress = enumIpAddr.nextElement();
                    if (!inetAddress.isLoopbackAddress() && !inetAddress.isLinkLocalAddress() ** inetAddress instanceof Inet4Address) {//换成Inet6Address 就可以拿到ipv6的地址
                        return inetAddress.getHostAddress();
                    }
                }
            }
        } catch (SocketException ex) {
            ex.printStackTrace();
        }
        return null;
    }
