Please guide : org.kodein.di.Kodein$NotFoundException: No binding found

Hi Team,

I am not sure if this is an issue or I am doing something wrong. Please guide.

Issue :

org.kodein.di.Kodein$NotFoundException: No binding found for bind<WeatherForecastDatabase>() with ?<CurrentWeatherFragment>().? { ? }
    Registered in this Kodein container:
            bind<CurrentWeatherDao>() with singleton { CurrentWeatherDao }
            bind<CurrentWeatherViewModelFactory>() with provider { CurrentWeatherViewModelFactory }
            bind<Unit>() with singleton { Unit }
            bind<WeatherNetworkDataSource>() with singleton { WeatherNetworkDataSourceImpl }
            bind<WeatherForecastRepository>() with singleton { WeatherForecastRepositoryImpl }
            bind<ConnectivityInterceptor>() with singleton { ConnectivityInterceptorImpl }
            bind<WeatherApiService>() with singleton { WeatherApiService }

I am using below grade dependencies,

implementation "org.kodein.di:kodein-di-generic-jvm:6.1.0"
implementation "org.kodein.di:kodein-di-framework-android-x:6.1.0"

Here is my Application class below, which I have also added in AndroidManifest.xml,

class WeatherForecastApplication : Application(), KodeinAware {

    override val kodein = Kodein.lazy {
        import(androidXModule(this@WeatherForecastApplication))

        bind() from singleton { WeatherForecastDatabase(instance()) }

        bind() from singleton { instance<WeatherForecastDatabase>().getCurrentWeatherDao() }

        bind<ConnectivityInterceptor>() with singleton { ConnectivityInterceptorImpl(instance()) }

        bind() from singleton { WeatherApiService(instance()) }

        bind<WeatherNetworkDataSource>() with singleton { WeatherNetworkDataSourceImpl(instance()) }

        bind<WeatherForecastRepository>() with singleton { WeatherForecastRepositoryImpl(instance(), instance()) }

        bind() from provider { CurrentWeatherViewModelFactory(instance()) }
    }

    override fun onCreate() {
        super.onCreate()

        // init threetenbp library.
        AndroidThreeTen.init(this)
    }

}

And this is how I am referencing instances in Fragment,

class CurrentWeatherFragment : Fragment(), KodeinAware {
    override val kodein by kodein()
    private val factory: CurrentWeatherViewModelFactory by instance()

    private lateinit var viewModel: CurrentWeatherViewModel

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        return inflater.inflate(R.layout.current_weather_fragment, container, false)
    }

    override fun onActivityCreated(savedInstanceState: Bundle?) {
        super.onActivityCreated(savedInstanceState)
        viewModel = ViewModelProviders.of(this, factory).get(CurrentWeatherViewModel::class.java)
    }
}

I am facing a similar issue: No binding found for bind<Activity>() with ?<MainActivity>().? { ? } Registered in this Kodein container:

Kodein Version : 6.1.0

My Activity Code class MainActivity : AppCompatActivity(), KodeinAware { override val kodein by kodein() private val fusedLocationProviderClient: FusedLocationProviderClient by instance() ............................... .............................. }

@SalomonBrys

I did recheck my WeatherForecastDatabase as suggested by you, and found that although it is a class, the function that was used to get an instance of this class returned nothing, which essentially meant Unit. Have made proper change and was able to get the app running.

Thanks a lot for your input. I had no clue that this could be a problem even though I read the crash logs mentioned above so many times. Had given up…

Maybe the team can add this in one of their README, as when this can happen and how to solve it?

Thanks again!

hi…please display your change in function into WeatherForecastDatabase…Because I have such a problem
