### Android Development Practices
- MVVM architecture (existing)
- Dependency injection (existing)
- Coroutines for async operations
- Room database integration

## 📞 Support & Troubleshooting

### If build fails:
1. Check all imports are correct
2. Ensure Gradle sync is complete
3. Check Kotlin version compatibility
4. Clear Gradle cache: `./gradlew clean`

### If screens don't appear:
1. Check navigation route names
2. Verify NavHost startDestination
3. Check composable function signatures
4. Verify callbacks are passed correctly

### If styling looks wrong:
1. Check color hex codes
2. Verify Font imports
3. Check device theme settings
4. Test on different Android versions
