@arnaud.giuliani We have been using Koin 2.0.1 in our Android SDK library. In our use case, the consuming application need to maintain two different instance of the SDK (based on different config passed). In koin 1.0, there was issue of scoping wherein the latest config passed would override the previous one. That was fixed in Koin 2.0.1 by implementing KoinComponent
and overriding the

getKoin() : Koin {
 return //custom koin instance maintained as a HashMap
}

but now once we have updated to 2.1.5 , we are again facing the issue. Is there a particular change in scoping in the latest release ?

[arnaud.giuliani]

2.1.5 introduced revamped Scope API

[arnaud.giuliani]

can you share a sample?

[Rohil Chodankar]

// Koin set up
object WrapperClass {
private val koinInstanceMap = HashMap<String, Koin>()

fun init() {
koinapplication = koinApplication {
  androidContext(context)
  modules(modules)
}

val instance =. CustomInstance()
koinapplication.koin.declare(instance)

koinInstanceMap[Id] = koinapplication.koin
}
}


Class CustomInstance : KoinComponent {

fun getKoin() : Koin {
  return koinInstanceMap[Id].koin
}

}

[Rohil Chodankar]

above is our setup. We maintain koinInstanceMap
to hold both the koin instance

@arnaud.giuliani Do let me know if you need more information, any help will be much appreciated

[arnaud.giuliani]

what is the error behind that exactly?

[arnaud.giuliani]

any stacktrace?

[Rohil Chodankar]

There isnt a error or exception. But basically the init function above receives a Configuration object. The consuming application calls init
twice with different configuration object as it needs two SDK instances. But the second configuration object overrides the first one whenever the dependency is provided

[Rohil Chodankar]

we faced the issue with Koin 1.0 but with Koin 2.0.1 it worked. Now with the latest update to 2.1.5 we are again facing that issue

[Rohil Chodankar]

fun getKoin() : Koin {
  return koinInstanceMap[Id].koin
}

Since i am storing both the KoinApplication instance, the overriding issue should not have occurred. @arnaud.giuliani

[arnaud.giuliani]

can you extract a small github project?

[arnaud.giuliani]

it’s hard here to help you like that

[Rohil Chodankar]

Any initial thoughts of why it would cause the issue ?

[arnaud.giuliani]

not sure 😕

[arnaud.giuliani]

don’t know if there is a leak or something

[arnaud.giuliani]

at least I can try to have 2 isolated Koin instances ... but I think we already have such tests

[Rohil Chodankar]

so the configuration instance passed to init we give to koin as module { single {
ConfigObject()
}
}

[Rohil Chodankar]

And later inject that in our use cases and view models

[arnaud.giuliani]

please put it somewhere on github, gists or something ... here in slack it’s just unreadable

[Rohil Chodankar]

yes will do
