I did a minuscule amount of app development for android back in the like 4.0 days, and recently tried again, using kotlin and jetpack or whatever their UI kit is. It was awful. Everything is so hard to use. Your UI framework requires you to define completely separate """magic""" functions to preview how it is rendered, as if that makes any sense. All documentation seems to make the classic blunder of assuming you already know the answer, already are an expert in the platform, and already know what you are doing. Every example either hides some magic that they had to add, or requires you already know everything that the example should be teaching you.

I literally feel like I understand the Windows Win32 dev ecosystem, and I've never written a Windows app in my life.
