How Hilt Simplifies Dependency Injection in Android

In any growing Android app, managing dependencies manually is a tiresome process. To create objects, pass them around, and placing them in the right place, makes the app bloated, and tightly coupled. It’s hard to test, hard to scale, and easy to break. So what’s a better way?

Challenge:

How to add dependencies in Android without writing tons of boilerplate?

Solution:

Use Hilt. It takes care of dependency injection with just a few annotations—no more manual setup or custom factories.

// AppModule.kt
@Module
@InstallIn(SingletonComponent::class)
object AppModule { @Provides fun provideRepo(): UserRepository = UserRepositoryImpl()
}
// MyActivity.kt
@AndroidEntryPoint
class MyActivity : AppCompatActivity() { @Inject lateinit var repository: UserRepository
}

Conclusion:

Hilt takes the pain out of dependency management. Your code stays modular, easier to test, and easier to scale. For any serious Android project or any team hiring experienced Android developers, Hilt isn’t just helpful, it’s essential for keeping the architecture clean and maintainable.
