PC客户端与Android服务端的Socket同步通信（USB）(转载)

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";

@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");
}
}

}

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.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")) {
/* 准备接收文件数据 */
try {
out.write("service receive OK".getBytes());
out.flush();
} catch (IOException e) {
e.printStackTrace();
}

/* 接收文件数据，4字节文件长度，4字节文件格式，其后是文件数据 */

filebytes = receiveFileFromSocket(in, out, filelength,
fileformat);

// Log.v(Service139.TAG, "receive data =" + new

try {

File file = FileHelper.newFile("R0013340.JPG");
FileHelper.writeFile(file, filebytes, 0,
filebytes.length);
} catch (IOException e) {
e.printStackTrace();
}
} else if (currCMD.equals("exit")) {

}
} catch (Exception e) {
// try {

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

out.close();
in.close();
} catch (Exception e) {
Log.e(androidService.TAG, Thread.currentThread().getName()

e.printStackTrace();
} finally {
try {
if (client != null) {
Log.v(androidService.TAG, Thread.currentThread().getName()
+ "---->" + "client.close()");
client.close();
}
} catch (IOException e) {
Log.e(androidService.TAG, Thread.currentThread().getName()
+ "---->" + "read write error333333");
e.printStackTrace();
}
}
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) {

}

out.flush();
} else if (currCMD.equals("2")) {

out.flush();
} else if (currCMD.equals("3")) {
out.write("OK".getBytes());
out.flush();
} else if (currCMD.equals("4")) {
/* 准备接收文件数据 */
try {
out.write("service receive OK".getBytes());
out.flush();
} catch (IOException e) {
e.printStackTrace();
}

/* 接收文件数据，4字节文件长度，4字节文件格式，其后是文件数据 */
byte[] filelength = new byte[4];
byte[] fileformat = new byte[4];
byte[] filebytes = null;

/* 从socket流中读取完整文件数据 */
filebytes = receiveFileFromSocket(in, out, filelength,
fileformat);

// Log.v(Service139.TAG, "receive data =" + new

}
} catch (Exception e) {

client.close();
}
} catch (IOException e) {
Log.e(androidService.TAG, Thread.currentThread().getName()
+ "---->" + "read write error333333");
e.printStackTrace();
}
}

6.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;
}
/**

*
* 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;
}

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。

9.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。
