Digit Recogntion using OpenCV on android

Question

I'm a first time Android and OpenCV developer and I would very much appreciate your help and some advise. I would like to extract and identify digits inputted by a mobile phone camera.

How do i approach this? What would be the best way to approach it and what are the steps?

It would help me very much if you could be as specific as possible.
