[DaveBoy]

i want to di double object like this:

val objectModel= module{
    single { ObjectBoxUtil.boxStore.boxFor<Song>() }
    single{ ObjectBoxUtil.boxStore.boxFor<Album>() }
}

when i add one of them,it's ok but when i add the second one:

     Caused by: org.koin.core.error.DefinitionOverrideException: Already existing definition or try to override an existing one: [type:Single,primary_type:'io.objectbox.Box']

i change it to this:

val objectModel= module{
    single (named("song")){ ObjectBoxUtil.boxStore.boxFor<Song>() }
    single (named("album")){ ObjectBoxUtil.boxStore.boxFor<Album>() }
}

it become this error:

        at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2746)

the other code

//init
        startKoin {
            // use AndroidLogger as Koin Logger - default Level.INFO
            androidLogger()

            // use the Android context given there
            androidContext(this@App)

            // module list
            modules(objectModel)
        }

//use
    val songBox:Box<Song> by inject()

what's the correct action? please help me.thanks

The problem is that Koin works in runtime and has no information about generics. You can find in the documentation

i use it like this in MainActivity

//use
    val songBox:Box<Song> by inject()

[kirich1409]

You need to use the same qualifier in declaration and injection:

val objectModel= module {
    single (named("song")){ ObjectBoxUtil.boxStore.boxFor<Song>() }
    single (named("album")){ ObjectBoxUtil.boxStore.boxFor<Album>() }
}

val songBox:Box<Song>  by inject(qualifier = named("song"))
val songBox:Box<Album> by inject(qualifier = named("album"))
