By layer or feature? Why not both?! Guide to Android app modularization

on YouTube ↗05m

" summary

Gradle-based examples show three concrete strategies—layered (data, domain, UI), feature (books, authors, reviews), and a hybrid Layer+Feature modularization that splits each layer into per-feature modules. The claim is that the hybrid raises cohesion, coupling, granularity: modules are smaller, highly specialized, and only depend on modules in the layer below (UI → domain → data), data modules cannot access upper layers, and feature reuse and isolated compilation improve as the codebase scales; references include the "Guide to Android app modularization" and Now in Android.
