Write code to check bubble type answer sheets on android with OpenCV

I have a grading app on android and I need to add function to use camera on android devices to check three types of test papers. I have uploaded the three types of paper that can be checked by my app. I need someone who can give me code for opencv in android to add in my app.

For example, on the 20 items answer sheet, the desired function is to detect the test paper from the camera and then capture photo, then detect all bubbles in the test paper and extract the shaded bubble for each item. Then compare it to the answer key to get the score of the paper.

Basically, It's an android app with Optical Mark recognition to check answer sheets for quizzes, but I only need someone to do the opencv programming in android, the rest I will do myself. The app is just like the existing app called ZIPGRADE. Kindly search it on google play store to get more perspective on what I want to build.
