in application

    override fun onCreate() {
        super.onCreate()
        val cicerone = Cicerone.create()
        val mainModule: Module = module {
            single {
                Room.databaseBuilder(androidApplication(), RoomDataBase::class.java, "game_db")

                    repository = get()
                )
            }

        }

        startKoin {
            androidContext(this@App)
            modules(listOf(mainModule))
        }
    }

in fragment presenter call code

class AnalyticsFragment : BaseFragment(), AnalyticsFragmentContract.View {
    private val presenter: AnalyticsFragmentContract.Presenter by inject { parametersOf(this) }

what rules need add to proguard.txt?

[sereja93]

rules in https://insert-koin.io/docs/2.0/quick-references/experimental-features/#proguard-rule not working

-keepnames class android.arch.lifecycle.ViewModel 
-keepclassmembers public class * extends android.arch.lifecycle.ViewModel { public <init>(...); }
-keepclassmembers class com.lebao.app.domain.** { public <init>(...); }
-keepclassmembers class * { public <init>(...); }

[LaurentTreguier]

From the exception, it looks like you are using AndroidX. If that's the case, then maybe it could work by changing android.arch.lifecycle.ViewModel to androidx.lifecycle.ViewModel in the proguard rules.

anything resolved? @sereja93

I'm having the same issue, only this proguard rule made it work:
-keepclassmembers class * { public <init>(...); }
