UDP从AndroidEmulator（--Genymotion--）到本地主机服务器（10.0.2.2）不工作？ [英] UDP from AndroidEmulator (--Genymotion--) to localhost Server(10.0.2.2) does not work?

问题描述

我只是尝试MonodroidApp（AndroidEmulator）和localDevServer之间发送和接收数据。我明白本地主机是专门映射为10.0.2.2的Andr​​oidEmulator，所以我做了以下，但应用程序没有响应。

I simply try to send and receive data between MonodroidApp(AndroidEmulator) and a localDevServer. I understand localhost is specially mapped to "10.0.2.2" on AndroidEmulator, so I did the following, but the app does not respond.

    System.Text.Encoding enc = System.Text.Encoding.UTF8;
        string sendMsg = "testtest";
        byte[] sendBytes = enc.GetBytes(sendMsg);

        int localPort = 39000;
        var udp = new System.Net.Sockets.UdpClient(localPort);

        //send data
        string remoteHost = "10.0.2.2";//"127.0.0.1";
        int remotePort = 15000;
        udp.Send(sendBytes, sendBytes.Length,
            remoteHost, remotePort);

        //receive data
        System.Net.IPEndPoint remoteEP = null;
        byte[] rcvBytes = udp.Receive(ref remoteEP);
        string rcvMsg = enc.GetString(rcvBytes);
        Console.WriteLine("received data:{0}", rcvMsg);
        Console.WriteLine("sender address:{0}/port:{1}",
            remoteEP.Address, remoteEP.Port);

这code被证实与单声道工作的Mac和使用指针localDevServer：远程主机=127.0.0.1

This code is verified to work with Mono for Mac and the localDevServer with the pointer: remoteHost = "127.0.0.1"

所以，

REMOTEHOST =10.0.2.2的模式是行不通的。

remoteHost = "10.0.2.2" pattern does not work.

我怎么会错过？任何人，任何想法？

What do I miss? Anyone, any thought?

感谢你。

推荐答案

好，一个重要的事情，我忘了提的是 我使用的为Android模拟器是Genymotion。

Ok, one important thing I forgot to mention is The emulator I use for android is Genymotion.

因此​​，这似乎是，10.0.2.2并不本地主机指向默认

So, it appears to be that "10.0.2.2" does not point localhost as default.

在我的环境中（OSX 10.9）与Genymotion，从仿真器的本地主机地址

In my environment(OSX 10.9) with Genymotion,the localhost address from the emulator is

10.0.3.2 ，和code ++工程。

"10.0.3.2", and the code works.
