@antoxa2584x Thank you for your pull request. :) The first commit[e038a26] looks good to me. But I can't find any main changes to the c039b1a, eac9877. Could you explain more about them?

Second commit show more correct usage of kotlin functions. Last commit just Android Stuidio refactor. As I can see, you use not 3 spaces (tabulation) but 2 spaces.
