Inject Activity

Hi,

Koin is awesome but I’m having an issue. Some libraries, like Firebase Analytics, depend on the current Activity to perform some actions like setting a current screen.

class Analytics(private val activity: Activity) {

  private val firebaseAnalytics: FirebaseAnalytics = FirebaseAnalytics.getInstance(activity)

  fun setCurrentScreen(screenName: String) {
    firebaseAnalytics.setCurrentScreen(activity, screenName, null)
  }
}

class MainPresenter(analytics: Analytics) { 
    
}

class MainActivity : AppCompatActivity() {

  val presenter : MainPresenter by inject()

}

Is this possible with Koin? If yes, then I don’t see how.

I am using parameters like below @westonal.

LocationModule.class

factory { (activity: MainActivity) -> FusedLocationProviderClient(activity) }

MainActivity.class

val provider: FusedLocationProviderClient by inject { parametersOf(this@MainActivity) }

I 've add Koin parameters to release 0.9.0.

you will be able to use parameters in your definition. Given class:

class MyPresenter(val activity : MyActivity)

We can use parameters to be injected with by inject()

val module = applicationContext {
   factory { params -> MyPresenter(params["activity"])}
}

Injecting the parameter:

class MyActivity : AppCompatActivity(){
   
   // Ask for MyPresenter injection and provide parameters
   val presenter : MyPresenter by inject( parameters = mapOf("activity" to this))
}

stay tuned👍
