Thanks, I just gone through the link which you have sent.Also i downloaded the code and imported into eclipse IDE it works fine.
But, in my application i wanted to scan the Business card once the camera is ON and the OCR process should start without clicking and saving the image.
If you are looking for read made code, then that is not how things happen here at the Ranch.
Did you study the code you imported? Have you worked on Android applications before? What have you tried so far and where are you stuck?
