Приложение вылетает, когда на некоторых устройствах вызывается действие onCreate().

Question

Наше приложение вылетает на некоторых устройствах после загрузки экрана. Он работает плавно на наших тестовых устройствах, поэтому мы не можем предоставить логарифм ошибок. Таким образом, единственная проблема заключается в том, что наше приложение вылетает на некоторых устройствах после вызова метода onCreate.

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
    WindowManager.LayoutParams.FLAG_FULLSCREEN); 

    setVolumeControlStream(AudioManager.STREAM_MUSIC); 

    WindowManager wm = (WindowManager) this.getSystemService(Context.WINDOW_SERVICE); 
    Display display = wm.getDefaultDisplay(); 
    Point size = new Point(); 
    display.getSize(size); 
    screenWidth = size.x; 
    screenHeight = size.y; 
    screenSizeAverage = (screenWidth + screenHeight)/2; 

    this.gameStatus = 5; 
    this.isEnemiesStarted = false; 
    this.score = 0; 
    this.playerPos = 0; 

    prefs = this.getSharedPreferences("myPrefsKey", Context.MODE_PRIVATE); 
    bestScore = prefs.getInt("key", 0); 

    gameView = new GameView(this.getApplicationContext(), this); 
    gameView.setOnTouchListener(new View.OnTouchListener(){ 

     @Override 
     public boolean onTouch(View v, MotionEvent event) { 

      if(event.getAction() == android.view.MotionEvent.ACTION_DOWN) { 
       if(gameStatus == 1){ 
        if(isEnemiesStarted == false){ 
         isEnemiesStarted = true; 
        } 
        if(event.getX() < screenWidth/2 && event.getY() < screenHeight/2) { 
         if(playerPos != 1){ 
          gameView.setPlayerPos(screenSizeAverage/8, screenSizeAverage/8); 
          playerPos = 1; 
          score++; 
          gameView.playSound(1); 
         } 
        } 
        else if(event.getX() > screenWidth/2 && event.getY() < screenHeight/2) { 
         if(playerPos != 2){ 
          gameView.setPlayerPos(screenWidth - screenSizeAverage/8 - gameView.getPlayerWidth(), screenSizeAverage/8); 
          playerPos = 2; 
          score++; 
          gameView.playSound(1); 
         } 
        } 
        else if(event.getX() < screenWidth/2 && event.getY() > screenHeight/2) { 
         if(playerPos != 3){ 
          gameView.setPlayerPos(screenSizeAverage/8, screenHeight - screenSizeAverage/8 - gameView.getPlayerWidth()); 
          playerPos = 3; 
          score++; 
          gameView.playSound(1); 
         } 
        } 
        else if(event.getX() > screenWidth/2 && event.getY() > screenHeight/2) { 
         if(playerPos != 4){ 
          gameView.setPlayerPos(screenWidth - screenSizeAverage/8 - gameView.getPlayerWidth(), screenHeight - screenSizeAverage/8 - gameView.getPlayerWidth()); 
          playerPos = 4; 
          score++; 
          gameView.playSound(1); 
         } 
        } 
       } 
      } 

      else if (event.getAction() == android.view.MotionEvent.ACTION_UP) { 
       if(gameStatus == 3){ 
        if(gameView.getLoadStatus() == 2){ 
         gameView.closeGameOver(); 
         gameView.playSound(2); 
        } 
       } 
       else if(gameStatus == 4){ 
        if(gameView.getLoadStatus() == 1){ 
         gameView.setBestScore(bestScore); 
         gameView.setLoadStatus(2); 
        } else if(gameView.getLoadStatus() == 2){ 
         gameView.restartGame(); 
         gameView.setLoadStatus(0); 
         gameView.playSound(2); 
        } 
       } 
      } 

      return true; 
     } 

    }); 
    setContentView(gameView);

У меня такая же проблема на Samsung Galaxy S4 Mini. Проблема

display.getSize(size); 

Я не знаю почему. Для меня

DisplayMetrics metrics = context.getResources().getDisplayMetrics(); 
int width = metrics.widthPixels; 
int height = metrics.heightPixels; 

works.
