1、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Pcclient端发来的命令，来处理数据后，把结果发给PCclientPC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：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LGGW880就没有，要去下载个1. android默认手机端的IP为“127.0.0.1”2. 要想联通PC与android手机的sokcet，一定要用adbf
2、orward来作下端口转发才能连上socket.viewplaincopytoclipboardprint?Runtime.getRuntime().exec(adbforwardtcp:12580tcp:10086);Thread.sleep(3000);Runtime.getRuntime().exec(adbforwardtcp:12580tcp:10086);Thread.sleep(3000);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
3、，手机端再写个接收BroastcastReceive来接收这个Broastcast，在这个BroastcastReceive来启动servicepc端命令：viewplaincopytoclipboardprint?Runtime.getRuntime().exec(adbshellambroadcast-aNotifyServiceStart);Runtime.getRuntime().exec(adbshellambroadcast-aNotifyServiceStart);android端的代码:ServiceBroadcastReceiver.javaviewplaincopytocl

10、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newsocket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：viewplaincopytoclipboardprint?publicvoidrun()Log.d(androidService.TAG,Thread.currentThread().getName()+aclienthasconnectedtoserver!);BufferedOutputStreamout;BufferedInputStreamin;try/*PC端发来的数据msg*/Stri
