How would you make a countdown clock in android studio?

I have been trying to make an app and can not figure out how to make a simple countdown, any ideas?

Hi Bar, I managed to get the code to compile and run, although I did mean a countdown clock. I still needed a component that would count up as I am trying to make a push up app(just for learning purposes). Thank you very much 😊
