CameraPreview quality dropped

[g-rabah]

Step 3: Describe the problem:

hi,
I was using the classes under the common folder from a month ago for a barcode scanning. However, after updating to the new release the camera preview quality and accuracy dropped.
After some digging, I noticed that the requestedPreviewWidth, requestedPreviewHeight were lower than the previous version

	private final int requestedPreviewWidth = 480;
	private final int requestedPreviewHeight = 360;

so i tried changing that back the to the previous values

  private final int requestedPreviewWidth = 1280;    
  private final int requestedPreviewWidth = 480;

Unfortunately, that did not work and made the camera lag.
is there a workaround? or should I fall back to the previous release?

Thanks in advanced

@gkaldev can probably explain the recent change.

See discussion in #745, this is working as intended for now.
