PC客户端与Android服务端的Socket同步通信(USB)

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”

  1. 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";

@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");

}

}

}

  1. 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.write("OK".getBytes());

out.flush();

} else if (currCMD.equals("2")) {

out.write("OK".getBytes());

out.flush();

} else if (currCMD.equals("3")) {

out.write("OK".getBytes());

out.flush();

} else if (currCMD.equals("4")) {

filebytes.length);

  1. 如果是在PC端和android端的读写操作来while(true){}循环,这样socket流的结尾不好判断,不能用“-1”来判断,因为“-1”是只有在socket关闭时才作为判断结尾。

7.socket在out.write(bytes);时,要是数据太大时,超过socket的缓存,socket自动分包发送,所以对方就一定要用循环来多次读。最好的办法就是服务器和客户端协议好,比如发文件时,先写过来一个要发送的文件的大小,然后再发送文件;对方用这个大小,来循环读取数据。

android端接收数据的代码:

view plaincopy to clipboardprint?

/**

* 功能:从socket流中读取完整文件数据

*

* InputStream in:socket输入流

*

* byte[] filelength: 流的前4个字节存储要转送的文件的字节数

*

* byte[] fileformat:流的前5-8字节存储要转送的文件的格式(如.apk)

*

* */

public static byte[] receiveFileFromSocket(InputStream in,

OutputStream out, byte[] filelength, byte[] fileformat) {

byte[] filebytes = null;// 文件数据

try {

int filelen = MyUtil.bytesToInt(filelength);// 文件长度从4字节byte[]转成Int

String strtmp = "read file length ok:" + filelen;

out.write(strtmp.getBytes("utf-8"));

out.flush();

filebytes = new byte[filelen];

int pos = 0;

int rcvLen = 0;

while ((rcvLen = in.read(filebytes, pos, filelen - pos)) > 0) {

pos += rcvLen;

}

Log.v(androidService.TAG, Thread.currentThread().getName()

+ "---->" + "read file OK:file size=" + filebytes.length);

out.write("read file ok".getBytes("utf-8"));

out.flush();

} catch (Exception e) {

Log.v(androidService.TAG, Thread.currentThread().getName()

+ "---->" + "receiveFileFromSocket error");

e.printStackTrace();

}

return filebytes;

}

/**

*

* byte[] filelength: 流的前4个字节存储要转送的文件的字节数

*

* byte[] fileformat:流的前5-8字节存储要转送的文件的格式(如.apk)

*

* */

public static byte[] receiveFileFromSocket(InputStream in,

OutputStream out, byte[] filelength, byte[] fileformat) {

byte[] filebytes = null;// 文件数据

try {

int filelen = MyUtil.bytesToInt(filelength);// 文件长度从4字节byte[]转成Int

String strtmp = "read file length ok:" + filelen;

out.write(strtmp.getBytes("utf-8"));

out.flush();

filebytes = new byte[filelen];

int pos = 0;

int rcvLen = 0;

while ((rcvLen = in.read(filebytes, pos, filelen - pos)) > 0) {

pos += rcvLen;

}

Log.v(androidService.TAG, Thread.currentThread().getName()

+ "---->" + "read file OK:file size=" + filebytes.length);

out.write("read file ok".getBytes("utf-8"));

out.flush();

} catch (Exception e) {

e.printStackTrace();

}

return filebytes;

}

8.socket的最重要的机制就是读写采用的是阻塞的方式,如果客户端作为命令发起者,服务器端作为接收者的话,只有当客户端client用out.writer()写到输出流里后,即流中有数据service的read才会执行,不然就会一直停在read()那里等数据。

  1. 还要让服务器端可以同时连接多个client,即服务器端用new thread()来作数据读取操作。
