Tools and libraries that simplify Dependency Injection in Android?

Dependency Injection (DI) is a design pattern used in Android development to promote loose coupling and enhance testability. Here are some popular tools and libraries that simplify Dependency Injection in Android:

Dagger 2

Dagger 2 is a fully static, compile-time dependency injection framework for Java and Android. It uses annotations to manage DI, allowing for optimized performance and minimal boilerplate code.

Example:


        @Module
        class AppModule {
            @Provides
            fun provideContext(application: Application): Context {
                return application.applicationContext
            }
        }

        @Component(modules = [AppModule::class])
        interface AppComponent {
            fun inject(application: MyApplication)
        }

Koin

Koin is a lightweight dependency injection framework for Kotlin. It's easy to set up and doesn't require any annotations or code generation, making it ideal for developers looking for simplicity.

Example:


        val appModule = module {
            single { MyRepository() }
            viewModel { MyViewModel(get()) }
        }

        startKoin {
            androidContext(this@MyApplication)
            modules(appModule)
        }

Hilt

Hilt is built on top of Dagger and provides a standard way to incorporate DI into Android apps. It comes with built-in components and simplifies Dagger’s boilerplate.

Example:


        @HiltAndroidApp
        class MyApplication : Application()

        @AndroidEntryPoint
        class MainActivity : AppCompatActivity() {
            @Inject lateinit var myRepository: MyRepository
        }
