Hi There,
I am receiving following exception in some devices, can anyone help me to resolve?

Fatal Exception: java.lang.RuntimeException

Yes I am doing it. Here is the code...

interface RuntimeConfig {

var videoRepository: VideoRepository

}

class SingletonRuntimeConfig : RuntimeConfig {

companion object {

val instance = SingletonRuntimeConfig()

}

override var videoRepository: VideoRepository = videoRepositoryInstance

}

private val videoPlayer by lazy { VideoPlayer() }

private val staticTexts by lazy { StaticTexts() }

private val videoRepositoryInstance by lazy { VideoRepository() }

private val glideRequestOptions by lazy {

RequestOptions

.placeholderOf(R.drawable.white_background)

.error(R.drawable.white_background)

}

private val remoteConfig by lazy {

val remote = Firebase.remoteConfig

remote.setDefaultsAsync(R.xml.remote_config_defaults)

remote

}

val appModule = module {

single { videoPlayer }

single { staticTexts }

single { SingletonRuntimeConfig.instance as RuntimeConfig }

factory { get<RuntimeConfig>().videoRepository }

single {

Glide.with(androidContext())

.setDefaultRequestOptions(glideRequestOptions)

}

single { StorageUtils(androidContext()) }

single {

PreferenceHelper(

androidContext().getSharedPreferences(

"pref${androidContext().resources.getString(R.string.app_collection_id)}",

Context.MODE_PRIVATE

)

)

}

single { MultiProcessPreferencesHelper(androidContext()) }

}

val firebaseModule = module {

single {

val instance = FirebaseDatabase.getInstance()

instance.setPersistenceEnabled(true)

instance

}

single { FirebaseAuth.getInstance() }

single { Firebase.storage.reference }

single { remoteConfig }

}

val allModules = listOf(firebaseModule, appModule)

And here is the Application class where I initiate Koin:

open class BaseApplication : MultiDexApplication() {

override fun onCreate() {

super.onCreate()

// Start Koin

startKoin {

androidLogger()

androidContext(this@BaseApplication)

modules(allModules)

}

}

override fun onTerminate() {

super.onTerminate()

unloadKoinModules(allModules)

}

}

If this is the only case you actually use FirebaseDatabase.getInstance() yourself, another library might access and use it before. Does the same occur when you use createdAtStart with this declaration?

No, didn't try it yet. Will do and let you know. Thanks!
