Half Way to clean architecture
summary
An Android app with ~100k lines and 100 million installs migrates from a homemade event-bus mess to a layered Clean Architecture using MVP and RxJava, keeping repositories as singletons and converting layer-specific models at boundaries. Migration happens incrementally (no rewrite), led by two core engineers, refactored about five times, using Studio wizards and abandoning data binding when it hurt tests. Result: far better testability, faster delivery, fewer bugs, and safe rollbacks.
