I use the following notation with koin-android:3.3.0 :

singleOf<AndroidPreferences> { AndroidPreferencesImpl(GlobalScope) }

When I update to koin-android:3.4.1 this becomes a compilation error. What is the recommended migration path here?
AndroidPreferences is an interface, AndroidPreferencesImpl is a class

[Martin Sloup]

single { AndroidPreferenceImpl(GlobalScope) } bind AndroidPreferences::class

If you have GlobalScope defined in Koin module, then:

singleOf(::AndroidPreferenceImpl) bind AndroidPreferences::class

[Tobias Preuss]

Thank you! That works for me.

Was this changed marked as a breaking change in some version?

Also, how would you define GlobalScope in a module? In the constructor parameter of a class I have no knowledge about the specific type as in scope: CoroutineScope .

[arnaud.giuliani]

use the OptionDSL with singleOf style:

singleOf(::AndroidPreferenceImpl){ bind<AndroidPreferences>() }

[Tobias Preuss]

@arnaud.giuliani Are you missing out GlobalScope?

[arnaud.giuliani]

for this you need to keep functional style: single { GlobalScope }

[Tobias Preuss]

How would that match the Coroutine parameter in the constructor? See my question above.

@arnaud.giuliani Ping, in case you did not see my reply. Take your time if you are busy.

[arnaud.giuliani]

just inject Dispatchers type

[Tobias Preuss]

@arnaud.giuliani Can you please point me to example? How does injecting the dispatcher type (which I already do) help with resolving the scope within the class instance?
