Dependency Injection with Hilt and Koin.
Topics Covered
Hilt for Android
@HiltAndroidApp
class App : Application()
@Module
@InstallIn(SingletonComponent::class)
object AppModule {
@Provides @Singleton
fun provideDatabase(@ApplicationContext context: Context) =
Room.databaseBuilder(context, AppDatabase::class.java, "app.db").build()
@Provides
fun provideUserDao(db: AppDatabase) = db.userDao()
}
@HiltViewModel
class UserViewModel @Inject constructor(
private val repository: UserRepository
) : ViewModel()Koin for Multiplatform
val appModule = module {
single { HttpClient(getEngine()) }
single { UserRepository(get()) }
viewModel { UserViewModel(get()) }
}
// Start Koin
startKoin {
modules(appModule)
}
// Inject
val repository: UserRepository by inject()Testing with DI
@HiltAndroidTest
class UserViewModelTest {
@get:Rule val hiltRule = HiltAndroidRule(this)
@BindValue @JvmField
val repository: UserRepository = mockk()
@Inject lateinit var viewModel: UserViewModel
@Before fun setup() { hiltRule.inject() }
}Troubleshooting
| Issue | Resolution |
|---|---|
| "No binding for..." | Add @Provides or @Binds |
| ViewModel not injected | Use hiltViewModel() in Compose |

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
Common Integration Points
