두 번째 사운드의 재생성이 낮습니까?

Question

헤드셋의 버튼을 누르고 스피커폰을 통해 사운드를 재생 한 다음 10 초 오디오 클립을 녹음하고 싶습니다. 여기 내 코드는 다음과 같습니다.

 SoundPool soundPool; 
     HashMap<Integer, Integer> soundPoolMap; 
     soundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 100); 
     soundPoolMap = new HashMap<Integer, Integer>(); 
     soundPoolMap.put(SOUND_RECORD_ON, 
       soundPool.load(context, R.raw.on, 1)); 
     soundPoolMap.put(SOUND_RECORD_OFF, 
       soundPool.load(context, R.raw.off, 1)); 

     AudioManager mAudioManager = (AudioManager) context 
       .getSystemService(Context.AUDIO_SERVICE); 
     float streamVolumeMax = mAudioManager 
       .getStreamMaxVolume(AudioManager.STREAM_MUSIC); 

     if (recordStarted == false) { 
      try { // start recording 
       audioRecorder.start(); 
       recordStarted = true; 
       System.out.println(String.format("recording: %s", 
         recordStarted)); 

       mAudioManager.setMode(AudioManager.MODE_IN_CALL); 
       mAudioManager.setSpeakerphoneOn(true); 
       System.out.println("speaker on"); 
       soundPool.play(soundPoolMap.get(SOUND_RECORD_ON), 
         streamVolumeMax, streamVolumeMax, 1, 0, 1f); 

      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } else { // stop recording 
      try { 
       audioRecorder.stop(); 
       recordStarted = false; 
       System.out.println(String.format("recording: %s", 
         recordStarted)); 

       mAudioManager.setMode(AudioManager.MODE_IN_CALL); 
       mAudioManager.setSpeakerphoneOn(true); 
       System.out.println("speaker on"); 
       soundPool.play(soundPoolMap.get(SOUND_RECORD_ON), 
         streamVolumeMax, streamVolumeMax, 2, 0, 1f); 

      } catch (IOException e) { 
       e.printStackTrace(); 
      } 

첫 번째 사운드는 매우 양호한 무결성과 함께 훌륭한 스피커에서 재생됩니다. 그러나 녹음을 멈추기 위해 버튼을 다시 누르면 같은 클립을 사용해도 소리가 거의 들리지 않습니다. 다음은 logcat 추적입니다.

왜 이런 경우인지 알고 있습니까? 나는 첫 부분에서 스피커 폰을 거짓으로 다시 설정하지 않았다는 것을 알고 있습니다. 그렇게하면 소리는 헤드셋을 통해서만 재생됩니다. 나는 그것이 "존경 받기에는 너무 짧다"는 말을 의심하고있다. 대단히 감사합니다!

는 --------- MediaPlayer를 코드로 업데이트 -------------

if (action == KeyEvent.ACTION_DOWN) { 
     Log.e(TAG, "BUTTON PRESSED :D "); 

     AudioManager mAudioManager = (AudioManager) context 
       .getSystemService(Context.AUDIO_SERVICE); 
     MediaPlayer playOn = MediaPlayer.create(context, R.raw.on); 

     if (recordStarted == false) { 
      try { // start recording 

       audioRecorder.start(); 
       recordStarted = true; 
       System.out.println(String.format("recording: %s", 
         recordStarted)); 

       mAudioManager.setMode(AudioManager.MODE_IN_CALL); 
       mAudioManager.setSpeakerphoneOn(true); 
       System.out.println("speaker on"); 

       playOn.start(); 
       System.out.println("playing on tune"); 

      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } else { // stop recording 
      try { 
       audioRecorder.stop(); 
       recordStarted = false; 
       System.out.println(String.format("recording: %s", 
         recordStarted)); 

       playOn.start(); 
       System.out.println("playing off tune"); 

      } catch (IOException e) { 
       e.printStackTrace(); 
      } finally { 
       // mAudioManager.setSpeakerphoneOn(false); 
       // System.out.println("speaker off"); 
       // mAudioManager.setMode(AudioManager.MODE_NORMAL); 
      } 
     } // end else 
    } // end key down action 

확인 사운드를 재생하려면이 코드를 사용하지만, 2 소리를 여전히 조용합니다 (이전과 같은 문제) ... 더 많은 제안이 있습니까? : D

음악이 onReceive가 실행되는 동안 만 지속되기 때문에 BroadcastReceiver에서 음악을 재생하지 않아야합니다 (미디어 버튼을 감지 함). 따라서 녹음하기 전에 재생할 서비스를 만들어야했습니다.
