Componentization and Modular Event Message Bus in Meituan Android Apps

Meituan transformed its monolithic cash‑register apps into a component‑based architecture using WMRouter as the routing foundation and built a strongly‑constrained modular‑event message bus—leveraging annotations, generated interfaces, and LiveData—to ensure type‑safe, module‑scoped communication, improve code reuse, reduce coupling, and simplify maintenance.
