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)

<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

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"/>

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);

 }

}
