How to Avoid Chaos: Navigation as a Separate Logical Layer
summary
The talk examines navigation in Android apps and the problem that existing navigation libraries often lack strict rules, causing navigation logic to leak into the presentation layer and increase coupling. It presents the LANG project’s evolved approach (used in Skyeng) that defines navigation as a separate logical layer, showing a structure that cleanly separates navigation from presentation, scales across modules, and keeps development effort proportional to business scope regardless of nesting depth.
