android 模拟器和PC相互通信(IP +端口+ socket) 实现方法：android socket
①服务程序运行在PC端
②客户端程序运行在android模拟器
实现形式：由android 模拟器向服务程序发出消息，然后服务程序会送消息至模拟器。

注意要点：
一、服务程序在PC端，需要指定电脑的端口，以提供数据访问的渠道。

二、客户端程序需要同样的端口以及PC的ip地址进行socket联络
三、数据通信用进程方式实现，可以支持多个客户端访问
四、代码层面：
1、AndroidManifest.xml需要添加
<uses-permission android:name="android.permission.INTERNET" />以提供网络访问权限支持
2、部分模拟器版本和android-SDK版本不匹配，此时去掉AndroidManifest.xml中的
<uses-sdk android:minSdkVersion="15" />就不会报错。

3、PC的IP为实际上外网的IP，即，IPV4。

通过命令行cmd，ipconfig查询即可。

代码：
服务端：Java项目，运行于PC:
Package：com.android.server
name：ServerThread
客户端：android项目，运行于android模拟器
package ：com.android.client
name：MyClientActivity
代码：
服务程序代码：
package com.android.server;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import .ServerSocket;
import .Socket;
public class PCServer {
public static void main(String a[]) {
new ServerThread(5554).start();
}
}
class ServerThread extends Thread {
private int Port;
private ServerSocket serversocket = null;
private Socket client;
ServerThread(int port) {
Port = port;
}
public void run() {
try {
serversocket = new ServerSocket(Port);
while (true) {
client = serversocket.accept();
System.out.println("server accept");
try {
// 接收客户端消息
BufferedReader in = new BufferedReader(
new InputStreamReader(client.getInputStream()));
String str = in.readLine();
System.out.println("read:" + str);
// 向服务器发送消息
PrintWriter out = new PrintWriter(new BufferedWriter(
new OutputStreamWriter(client.getOutputStream())),
true);
out.println("MSG from server:Your message(" + str + ")has been successfully sent!");
// 关闭输入输出流
out.close();
in.close();
} catch (Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
} finally {
// 关闭客户端
client.close();
System.out.println("server close");
}
}
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
}
