Android Legacy Navigation Standards

Priority: P1 (HIGH)

1. Set Up Single-Activity Architecture

Use one Host Activity with NavHostFragment.
Enable SafeArgs plugin — MANDATORY for passing data between fragments.

See XML graph & SafeArgs examples for NavHostFragment setup.

2. Manage Navigation Graphs

Nested Graphs: Modularize navigation/ resources (e.g., nav_auth.xml, nav_main.xml) to keep graphs readable.
Deep Links: Define explicit <deepLink> in graph, not AndroidManifest intent filters.

3. Navigate with SafeArgs

See XML graph & SafeArgs examples for type-safe navigation usage.

Anti-Patterns

No Raw String Bundle Keys: Use SafeArgs generated type-safe classes.
No Manual Fragment commit(): Use NavController for all navigation.
