Thanks for the suggestion! I started with the Udacity course: Developing Android Apps with Kotlin. However, that was not enough. I knew exactly what I want to solve. I was facing specific problems so it was easier to google those problems and find the answers than following a course. I am not a good designer. I tried to make the design as right and as simple as the solution needs.
