Camera preview image data processing with Android L and Camera2 API

Question

I\'m working on an android app that is processing the input image from the camera and displays it to the user. This is fairly simple, I register a PreviewCallback

In the ImageReader.OnImageAvailableListener class, close the image after reading as shown below (this will release the buffer for next capture). You will have to handle exception on close

      Image image =  imageReader.acquireNextImage();
      ByteBuffer buffer = image.getPlanes()[0].getBuffer();
      byte[] bytes = new byte[buffer.remaining()];
      buffer.get(bytes);
      image.close();
