title: Curious about Camera Width and height in andEngine
body: <p>I looked at many examples of andEngine Gles2.0 All of them take these :</p>
  
  <pre><code>private static final int CAMERA_WIDTH = 720;
  private static final int CAMERA_HEIGHT = 480;
  </code></pre>
  
  <p>Why is this value fixed? Why can't I do this:</p>
  
  <pre><code>int currentapiVersion = android.os.Build.VERSION.SDK_INT;
  int honeyComb = android.os.Build.VERSION_CODES.HONEYCOMB_MR2;
  
  Display display = getWindowManager().getDefaultDisplay();
  if (currentapiVersion &gt;= honeyComb) {
      Point size = new Point();
      display.getSize(size);
      CAMERA_WIDTH = size.x;
      CAMERA_HEIGHT = size.y;
  } else {
      CAMERA_WIDTH = display.getWidth();
      CAMERA_HEIGHT = display.getHeight();
  }
  </code></pre>
