1. 启动模拟器，部署应用

2. 利用模拟器控制器发送短信启动服务（查看日志输出判断是否成功）

3. 向模拟器拨打电话，并接听，挂断电话后，利用文件管理查看对应的cache目录或者sdcard中生成了3gp文件，并将其复制到pc中播放以验证。

清单设置（一个receiver，一个service，若干权限）
view plainprint?

    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>

    <uses-permission android:name="android.permission.RECORD_AUDIO"/>

    <uses-permission android:name=

                         "android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>

    <uses-permission android:name=

                         "android.permission.WRITE_EXTERNAL_STORAGE"/>

    <uses-permission android:name="android.permission.RECEIVE_SMS"/>

    …

    <application …>

            <receiver android:name="BootBroadcastReceiver">

                <intent-filter>

                    <action android:name=

                               "android.provider.Telephony.SMS_RECEIVED"/>

                </intent-filter>

            </receiver>

            <service android:name="PhoneListenerService" />

电话监听器服务类：PhoneListenerService
view plainprint?

    package cn.class3g.phonelistener;

    ...

    public class PhoneListenerService extends Service {

    public IBinder onBind(Intent arg0) {

     return null;

     }

     public void onCreate() {

     super.onCreate();

     Log.i("TAG", "服务启动了");

     // 对电话的来电状态进行监听

    TelephonyManager telManager = (TelephonyManager) this

     .getSystemService(Context.TELEPHONY_SERVICE);

     // 注册一个监听器对电话状态进行监听

    telManager.listen(new MyPhoneStateListener(),

     PhoneStateListener.LISTEN_CALL_STATE);

     }

     private class MyPhoneStateListener extends PhoneStateListener {

     MediaRecorder recorder;

     File audioFile;

     String phoneNumber;

     public void onCallStateChanged(int state, String incomingNumber) {

     switch (state) {

     case TelephonyManager.CALL_STATE_IDLE: /* 无任何状态时 */

    if (recorder != null) {

     recorder.stop();// 停止刻录

    recorder.reset();// 重设

    recorder.release();// 刻录完成一定要释放资源

    }

    break;

     case TelephonyManager.CALL_STATE_OFFHOOK: /* 接起电话时 */

    try {

     recorder = new MediaRecorder();

     recorder.setAudioSource(MediaRecorder.AudioSource.MIC); // 设置音频采集原

    recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);// 内容输出格式

    recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); // 音频编码方式

    // recorder.setOutputFile("/sdcard/myvoice.amr");

     audioFile = new File(

     Environment.getExternalStorageDirectory(),

     phoneNumber + "_" + System.currentTimeMillis()

     + ".3gp");

     recorder.setOutputFile(audioFile.getAbsolutePath());

     Log.i("TAG", audioFile.getAbsolutePath());

     recorder.prepare(); // 预期准备

    recorder.start();

     } catch (IllegalStateException e) {

     e.printStackTrace();

     } catch (IOException e) {

     e.printStackTrace();

     }

     break;

     case TelephonyManager.CALL_STATE_RINGING: /* 电话进来时 */

    phoneNumber = incomingNumber;

     break;

     default:

     break;

     }

     super.onCallStateChanged(state, incomingNumber);

     }

     }

    }

利用开机启动广播启动服务（实验环境中为了方便起见可以先改用短消息广播）

开机启动完成广播action

<action android:name="android.intent.action.BOOT_COMPLETED"/>
view plainprint?

    package cn.class3g.phonelistener;

    ...

    public class BootBroadcastReceiver extends BroadcastReceiver {

     public void onReceive(Context context, Intent intent) {

     Log.i("TAG", "广播被接收了");

    Intent serviceIntent = new Intent(context, PhoneListenerService.class);

     context.startService(serviceIntent);

     }

    }
