Hello All, I started doing Android Developement a few months back and till now I was only sharing my learnings on Twitter and this project was stored locally on my system but now I have shared the code on Github with comments to help you more.

Description - This project is a basic Arithmetic addition app in which you have 30 seconds to solve as many questions as you want, there is a timer and a score counter Each question has 4 options.

         Here I used Android buttons for Options and other actions like GO button
         Text Views and Layouts like Grid and Constraint Layout, and a CountDown Timer
         
         Rest all I hope would be clear from the code.
