How to migrate to Koin from an older API?

Migrating to Koin from an older dependency injection API can significantly simplify your code and improve the maintainability of your Android applications. This guide will help you through the process step-by-step.

Step 1: Add Koin Dependency

First, include the Koin dependencies in your build.gradle file:


    dependencies {
        implementation "io.insert-koin:koin-android:3.x.x" // replace x.x with latest version
    }

Step 2: Define Modules

Create a new Kotlin file for defining Koin modules. Here's an example module definition:


    val appModule = module {
        single { Repository() }
        viewModel { MainViewModel(get()) }
    }

Step 3: Start Koin

Initialize Koin in your Application class:


    class MyApplication : Application() {
        override fun onCreate() {
            super.onCreate()
            startKoin {
                androidContext(this@MyApplication)
                modules(appModule)
            }
        }
    }

Step 4: Inject Dependencies

Now you can inject dependencies in your Activities or Fragments:


    class MainActivity : AppCompatActivity() {
        private val viewModel: MainViewModel by viewModel()
        
        override fun onCreate(savedInstanceState: Bundle?) {
            super.onCreate(savedInstanceState)
            setContentView(R.layout.activity_main)
            // Use your viewModel here
        }
    }

Conclusion

With these steps, you've successfully migrated to Koin from your previous dependency injection API. Enjoy the improved simplicity and power of Koin!
