title: Google Drive OCR Android
body: <p>I've downloaded Google drive sdk for Android,
  the API is not well documented, so I didn't manage to get to conclusion if what I want to do is possible.
  I want to capture an image with the camera convert it to black and white pdf, and then perform OCR on it to get the fields I need as String.
  Do I need to send a server request for it or maybe I can Do it on the client side only using Drive api?
  sample code will be helpful.</p>
