Kotlin Multimodule Architecture Offers Scalable Solution for Large Android Apps

As Android applications grow in complexity, a single Gradle module becomes difficult to maintain due to longer build times and tightly coupled dependencies. A multimodule architecture addresses this by dividing the app into independently managed modules organized around business capabilities such as auth, orders, and payments. Each feature module can internally follow Clean Architecture principles, while shared functionality is provided through focused core modules covering networking, database, and UI. Dependency inversion through interfaces prevents direct feature-to-feature coupling, keeping modules loosely connected. Convention plugins further reduce repetition by centralizing Gradle configuration, allowing teams to build, test, and modify parts of the application independently.
