Build a modular Android app architecture

" summary

Argues that modularizing yields concrete wins: using an AndroidX dependency-discovery plugin cuts a pre-summit build from about two hours to 10–20 minutes; choose between layered modules (Room, Retrofit, Moshi, Dagger) for fast isolation and testing or feature modules (Android App Bundle + Play Core dynamic delivery) for on‑demand code like Plaid’s DesignerNews and Dribbble; share common interfaces via a DataSourceProvider and ServiceLoader/reflection for runtime discovery; Room will later support merged multi‑module DBs; start layered, move to feature when team scale demands.
