PC客户端与Android服务端的Socket同步通信（USB） 收藏 需求： 1.一个android端的service后台运行的程序，作为socket的服务器端;用于接收Pc client端发来的命令，来处理数据后，把结果发给PC client 2.PC端程序，作为socket的客户端，用于给android手机端发操作命令难点分析： 1.手机一定要有adb模式，即插上USB线时马上提示的对话框选adb。好多对手机的操作都可以用adb直接作。 不过，我发现LG GW880就没有，要去下载个 2.android默认手机端的IP为“127.0.0.1” 3.要想联通PC与android手机的sokcet，一定要用adb forward 来作下端口转发才能连上socket.view plaincopy to clipboardprint?Runtime.getRuntime().exec(adb forward tcp:12580 tcp:10086); Thread.sleep(3000); Runtime.getRuntime().exec(adb forward tcp:12580 tcp:10086);Thread.sleep(3000); 4.android端的service程序Install到手机上容易，但是还要有方法来从PC的client端来启动手机上的service ，这个办法可以通过PC端adb命令来发一个Broastcast ，手机端再写个接收BroastcastReceive来接收这个Broastcast，在这个BroastcastReceive来启动service pc端命令： view plaincopy to clipboardprint?Runtime.getRuntime().exec( adb shell am broadcast -a NotifyServiceStart); Runtime.getRuntime().exec(adb shell am broadcast -a NotifyServiceStart); android端的代码:ServiceBroadcastReceiver.java view plaincopy to clipboardprint?package com.otheri.service; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.util.Log; public class ServiceBroadcastReceiver extends BroadcastReceiver private static String START_ACTION = NotifyServiceStart; private static String STOP_ACTION = NotifyServiceStop; Override public void onReceive(Context context, Intent intent) Log.d(androidService.TAG, Thread.currentThread().getName() + - + ServiceBroadcastReceiver onReceive); String action = intent.getAction(); if (START_ACTION.equalsIgnoreCase(action) context.startService(new Intent(context, androidService.class); Log.d(androidService.TAG, Thread.currentThread().getName() + - + ServiceBroadcastReceiver onReceive start end); else if (STOP_ACTION.equalsIgnoreCase(action) context.stopService(new Intent(context, androidService.class); Log.d(androidService.TAG, Thread.currentThread().getName() + - + ServiceBroadcastReceiver onReceive stop end); package com.otheri.service;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.util.Log;public class ServiceBroadcastReceiver extends BroadcastReceiver private static String START_ACTION = NotifyServiceStart;private static String STOP_ACTION = NotifyServiceStop;Overridepublic void onReceive(Context context, Intent intent) Log.d(androidService.TAG, Thread.currentThread().getName() + -+ ServiceBroadcastReceiver onReceive);String action = intent.getAction();if (START_ACTION.equalsIgnoreCase(action) context.startService(new Intent(context, androidService.class);Log.d(androidService.TAG, Thread.currentThread().getName() + -+ ServiceBroadcastReceiver onReceive start end); else if (STOP_ACTION.equalsIgnoreCase(action) context.stopService(new Intent(context, androidService.class);Log.d(androidService.TAG, Thread.currentThread().getName() + -+ ServiceBroadcastReceiver onReceive stop end); 5.由于是USB连接，所以socket就可以设计为一但连接就一直联通，即在new socket和开完out,in流后，就用个while(true)来循环PC端和android端的读和写 android的代码：view plaincopy to clipboardprint?public void run() Log.d(androidService.TAG, Thread.currentThread().getName() + - + a client has connected to server!); BufferedOutputStream out; BufferedInputStream in; try /* PC端发来的数据msg */ String currCMD = ; out = new BufferedOutputStream(client.getOutputStream(); in = new BufferedInputStream(client.getInputStream(); / testSocket();/ 测试socket方法 androidService.ioThreadFlag = true; while (androidService.ioThreadFlag) try if (!client.isConnected() break; /* 接收PC发来的数据 */ Log.v(androidService.TAG, Thread.currentThread().getName() + - + will read.); /* 读操作命令 */ currCMD = readCMDFromSocket(in); Log.v(androidService.TAG, Thread.currentThread().getName() + - + *currCMD = + currCMD); /* 根据命令分别处理数据 */ if (currCMD.equals(1) out
