# Android Legacy Navigation Standards
## **Priority: P1**
## Implementation Guidelines
### Setup
- **Single Activity**: Use one Host Activity with a `NavHostFragment`.
- **SafeArgs**: MANDATORY for passing data between fragments.
### Graph Management
- **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 (Nav handles them).
## Anti-Patterns
- **Bundle Keys**: `**No "strings"**: Use SafeArgs generated classes.`
- **Fragment Transations**: `**No Manual commit()**: Use NavController.`
