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);
}
}
测试：
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）
