简易的android 通话录音实现【只能录制MIC的声音，不能录制对方的声音】

使用广播接收者实现自启动； 

      public class phoneService extends Service {
         @Override
         public IBinder onBind(Intent arg0) {
             // TODO Auto-generated method stub
             return null;
          }
         @Override
         public void onCreate() {
             // TODO Auto-generated method stub
             super.onCreate();
             TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
              telephonyManager.listen(new PhoneListener(), PhoneStateListener.LISTEN_CALL_STATE);
          }
         private final class PhoneListener extends PhoneStateListener{
             private MediaRecorder mediaRecorder;
             private File file;
             private Vibrator vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);
             @Override
             public void onCallStateChanged(int state, String incomingNumber) {
                 try {
                     switch (state){
                     case TelephonyManager.CALL_STATE_RINGING: //来电
                         break;

                          mediaRecorder = new MediaRecorder();
                          mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);

                          Toast.makeText(getApplicationContext(), "电话已接通，开始录音。", Toast.LENGTH_SHORT).show();
                         //震动一下
                          vibrator.vibrate(100);
                         break;
                     case TelephonyManager.CALL_STATE_IDLE: //挂断电话
                         if (mediaRecorder != null){
                              mediaRecorder.stop();
