Multi-module architecture is recommended for organizing an Android app effectively.
Building a production-grade app using a single-module architecture can lead to scalability and maintenance issues as the app grows.
Recommendation: Learn the fundamentals, explore architectural patterns, build small projects, and then transition to multi-module architecture for better scalability, maintainability, and performance.
Achievements: The author developed two applications using a multi-module architecture, which resulted in fewer bugs, easier scalability, and seamless feature additions.
