Topics Covered
MVVM Pattern
@HiltViewModel
class UserViewModel @Inject constructor(
private val repository: UserRepository
) : ViewModel() {
private val _uiState = MutableStateFlow(UiState())
val uiState = _uiState.asStateFlow()
fun load() = viewModelScope.launch {
_uiState.update { it.copy(isLoading = true) }
repository.getUsers()
.onSuccess { users -> _uiState.update { it.copy(users = users, isLoading = false) } }
}
}Compose UI
@Composable
fun UserScreen(viewModel: UserViewModel = hiltViewModel()) {
val state by viewModel.uiState.collectAsStateWithLifecycle()
UserContent(state)
}Type-Safe Navigation
@Serializable
data class ProfileRoute(val userId: String)
composable<ProfileRoute> { entry ->
val route: ProfileRoute = entry.toRoute()
}Troubleshooting
| Issue | Resolution |
|---|---|
| Recomposition loop | Mark class @Stable or use derivedStateOf |
| ViewModel recreated | Use hiltViewModel() not viewModel() |

Activity Basics
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
MyAppTheme {
MainScreen()
}
}
}
}ViewModel
class MainViewModel(
private val repository: UserRepository
) : ViewModel() {
private val _users = MutableStateFlow<List<User>>(emptyList())
val users: StateFlow<List<User>> = _users.asStateFlow()
fun loadUsers() {

}
}
}Kotlin Android Patterns
Design Patterns
Pattern 1: Input Validation
Always validate input before processing:
def validate_input(data):
if data is None:
raise ValueError("Data cannot be None")
if not isinstance(data, dict):
raise TypeError("Data must be a dictionary")
return TruePattern 2: Error Handling
Use consistent error handling:
try:
result = risky_operation()
except SpecificError as e:
logger.error(f"Operation failed: {e}")
handle_error(e)
except Exception as e:
logger.exception("Unexpected error")
raisePattern 3: Configuration Loading
Load and validate configuration:
import yaml
def load_config(config_path):
with open(config_path) as f:
config = yaml.safe_load(f)
validate_config(config)
return configAnti-Patterns to Avoid
❌ Don't: Swallow Exceptions
# BAD
try:
do_something()
except:
pass✅ Do: Handle Explicitly
# GOOD
try:
do_something()
except SpecificError as e:
logger.warning(f"Expected error: {e}")
return default_valueCategory-Specific Patterns: General
Recommended Approach
1. Start with the simplest implementation 2. Add complexity only when needed 3. Test each addition 4. Document decisions
