Functional Android

" summary

Argues that adopting Kotlin, RxJava, Arrow and MVI yields concrete gains: pure functions with inputs-only behavior let unit tests run without heavy setup, immutable data models eliminate thread races, and higher‑order functions reduce boilerplate. Shows a Buffer viewmodel that maps actions to UI states (errors treated as data), demonstrates a buggy RxJava merge where two threads mutate the same burger then fixes it by returning new immutable burgers, and points to Biscotti espresso helpers that wrap setup/verify steps.
