android 模拟器和PC相互通信

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-permissionandroid: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
