Dependency Injection You Can Start Today
summary
Explains dependency injection (DI) for Android apps: why DI removes hard-coded dependencies to make large apps easier to test and customize, and how to apply DI in Android projects. Compares and shows implementations with two DI containers—Dagger (Google’s popular solution) and Koin (a Kotlin-based alternative)—and covers how DI affects writing unit and UI tests.
