HoangNguyen0403 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.
