电脑在Android的USB绑定模式没有WIFI，编程方式的IP地址 [英] Ip address of PC in USB Tethering mode in Android without WIFI, Programatically

问题描述

我如何编程得到其Android手机连接在USB绑定模式的PC的IP地址，默认网关和端口号，而无需使用WIFI经理？

我使用的网络接口，但它不给我正确的信息，还有没有别的办法？

 的（列举＆LT;的NetworkInterface＆GT; EN = NetworkInterface.getNetworkInterfaces（）; en.hasMoreElements（））{
            NetworkInterface的INTF = en.nextElement（）;
            对于（枚举＆LT; InetAddress类＆GT; enumIpAddr = intf.getInetAddresses（）; enumIpAddr.hasMoreElements（））{
                InetAddress类InetAddress类= enumIpAddr.nextElement（）;
                如果（！inetAddress.isLoopbackAddress（））{
                    。地址+ = inetAddress.getHostAddress（）的toString（）;
                }
            }
        }
 

解决方案

确定这里是一轮关于我达到了，从通过网络接口接收的地址，我在致辞中删除最后一个部分，如192.168.1.40解决方案我取出40，并通过循环遍历从192.168.1.0出发，找出实际连接的端口。该片段是低于

 的（IDX = 0; IDX＆LT; = 255; IDX ++）
         {
             尝试
             {
                 T [IDX] =新主题（新的Runnable（）{
                        公共无效的run（）{
                            海峡= IPpart +。 + IDX;
                                            插座=新的Socket（STR，PORT）;
                                   IP = socket.getInetAddress（）的toString（）。
                             网关= socket.getLocalAddress（）的toString（）。
                        }
                    }）;
                 T [IDX] .setName（IPclass）;
                 T [IDX]。开始（）;
                 如果（IP！=）
                 {
                     closeThread（）;
                     打破;
                 }
             }赶上（例外前）{}
         }
 

How can I programatically get the Ip address, default gateway and port number of the PC to which the android phone is connected in USB Tethering mode, without using WIFI Manager?

I used network interfaces, but it doesnt give me the correct information, is there any other way?

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()) {
                    address += inetAddress.getHostAddress().toString() ;
                }
            }
        }

解决方案

Ok here is the round about solution that I reached, from the address received through the network interface, I remove the last section in the address, like 192.168.1.40, i remove 40 and iterate through a loop starting from 192.168.1.0 and find out the port which actually connects. The snippet is below

for(idx=0; idx <=255; idx++)
         {
             try
             {
                 t[idx] = new Thread(new Runnable() {
                        public void run() {
                            str = IPpart + "." + idx;
                                            socket = new Socket(str, PORT);
                                   IP = socket.getInetAddress().toString();
                             Gateway = socket.getLocalAddress().toString();
                        }
                    });
                 t[idx].setName("IPclass");
                 t[idx].start();
                 if(IP != "")
                 {
                     closeThread();
                     break;
                 }
             }catch(Exception ex){ }
         }
