안드로이드 애플 리케이션의 사운드 풀에 대한 치명적인 예외

Question

나는 카메라 표면보기와 화재 사운드를 재생할 버튼이있는 게임을 개발 중입니다. 여러 번 활동을 시작한 후 앱이 충돌합니다. 스택 추적에서 사운드 풀의 오류를 보여줍니다.

public class MainActivity extends Activity implements SurfaceHolder.Callback,OnClickListener { 

Camera mCamera; 
SurfaceView mPreview; 
Button shoot; 
TextView rounds; 

int shootsound; 
int reloadsound; 

SoundPool spool; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    Bundle extras = getIntent().getExtras(); 
    if (extras != null) { 
    int btnNumber = extras.getInt("button"); 
    switch(btnNumber) 
    { 
     case 1 : setContentView(R.layout.activity_main); break; 
     case 2 : setContentView(R.layout.machinegun); break; 
    } 
    } 

    // Ads 
    new TapContextSDK(getApplicationContext()).initialize(); 
    new TapContextSDK(getApplicationContext()).showAd(); 

    mPreview = (SurfaceView)findViewById(R.id.preview); 
    mPreview.getHolder().addCallback(this); 
    mPreview.getHolder().setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); 

    mCamera = Camera.open(); 
    shoot=(Button)findViewById(R.id.button1); 
    shoot.setOnClickListener(this); 
    rounds=(TextView)findViewById(R.id.textView1); 

    //SOUND POOL 
    this.setVolumeControlStream(AudioManager.STREAM_MUSIC); 
    spool = new SoundPool(1, AudioManager.STREAM_MUSIC, 0);  
    shootsound= spool.load(this, R.raw.shoot, 2); 
    reloadsound= spool.load(this, R.raw.reload, 2); 
} 

@Override 
public void onPause() { 
    super.onPause(); 
    mCamera.stopPreview(); 
} 

@Override 
public void onDestroy() { 
    super.onDestroy(); 
    mCamera.release(); 
} 

@Override 
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {  
    Parameters parameters = mCamera.getParameters(); 
    List<Camera.Size> previewSizes = parameters.getSupportedPreviewSizes(); 
    Camera.Size previewSize = previewSizes.get(4); //480h x 720w 

    parameters.setPreviewSize(previewSize.width, previewSize.height); 
    parameters.setFlashMode(Parameters.FLASH_MODE_AUTO); 
    parameters.setFocusMode(Camera.Parameters.FOCUS_MODE_AUTO); 

    mCamera.setParameters(parameters); 

    Display display = ((WindowManager)getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay(); 
    if(display.getRotation() == Surface.ROTATION_0) {       
     mCamera.setDisplayOrientation(90); 
    } else if(display.getRotation() == Surface.ROTATION_270) { 
     mCamera.setDisplayOrientation(180); 
    } 

    mCamera.startPreview(); 
} 

@Override 
public void surfaceCreated(SurfaceHolder holder) { 
    try { 
     mCamera.setPreviewDisplay(mPreview.getHolder()); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
} 

@Override 
public void surfaceDestroyed(SurfaceHolder holder) { 
    Log.i("PREVIEW","surfaceDestroyed"); 
} 

//shoot sound 
public void shoot(){ 
    AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE); 
    float volume = (float) audioManager.getStreamVolume(AudioManager.STREAM_MUSIC); 
    spool.play(shootsound, volume, volume, 1, 0, 1f); 
    } 

//reload sound 
public void reload(){ 
    AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE); 
    float volume = (float) audioManager.getStreamVolume(AudioManager.STREAM_MUSIC); 
    spool.play(reloadsound, volume, volume, 1, 0, 1f); 
    } 

//Vibrate 
public void vibrateMe() { 
    Vibrator vibrate = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE); 

    vibrate.vibrate(100); 
} 

@Override 
public void onClick(View arg0) { 
    // TODO Auto-generated method stub 

    switch(arg0.getId()) { 

    case R.id.button1: 

     int tmp = Integer.valueOf(rounds.getText().toString()); 

     if(tmp==0) 
     { 
      rounds.setText("12"); 
      reload(); 
     } 
     else 
     { 
      shoot(); 
      vibrateMe(); 
      rounds.setText(String.valueOf(tmp-1)); 
     } 
     break; 

} 
} 
}

모든 솔루션하세요?

Answer 1

코드에서 soundpool에 대한 더 릴리스 자원 없습니다 수행하는 것은 매우 중요하다 ... 어쩌면 SoundPool 활동을 재개 한 후 충돌을 일으키는 먹으 렴,

감사를 메모리 누수를 방지하기 위해!
