org.koin.core.error.InstanceCreationException: Could not create instance for #574

Closed caiolesk closed 5 years ago

caiolesk commented 5 years ago

I tried to consume my api. Following this steps.. https://medium.com/android-dev-br/modulariza%C3%A7%C3%A3o-android-parte-3-22622ae7d162

val presentationModule = module {

factory { AndroidItemAdapter() }

viewModel { MainViewModel(
        useCase = get(),
        uiScheduler = AndroidSchedulers.mainThread()
) }

}

val dataCacheModule = module { single { ItensDataBase.createDataBase(androidContext()) } factory { ItensCacheSourceImpl(itemDao = get()) } }

val repositoryModule = module { factory { AndroidItensRepositoryImpl( itensCacheDataSource = get(), remoteDataSource = get() ) } }

val dataModules = listOf(remoteDataSourceModule, repositoryModule, dataCacheModule)

val remoteDataSourceModule = module { factory { providesOkHttpClient() } single { createWebService( okHttpClient = get(), url = androidContext().getString(R.string.base_url) ) }

factory<RemoteDataSource> { RemoteDataSourceImpl(itemApi = get()) }

}

fun providesOkHttpClient(): OkHttpClient { return OkHttpClient.Builder() .connectTimeout(30, TimeUnit.SECONDS) .readTimeout(30, TimeUnit.SECONDS) .writeTimeout(30, TimeUnit.SECONDS) .build() }

inline fun createWebService(okHttpClient: OkHttpClient , url: String): T { return Retrofit.Builder() .addConverterFactory(GsonConverterFactory.create()) .addCallAdapterFactory(RxJava2CallAdapterFactory.create()) .baseUrl(url) .client(okHttpClient) .build() .create(T::class.java) }

val useCaseModule = module {

factory {
    GetItensUseCases(
            repository = get(),
            scheduler = Schedulers.io()
    )
}

}

val domainModule = listOf(useCaseModule)

override fun onCreate() { super.onCreate()

    startKoin {
        androidContext(this@MyModuleApplication)

        modules(domainModule + dataModules + listOf(presentationModule))
    }
}

@caiolesk what's the solution ?

check if your class Database @Database(version = 1, entities = [AndroidItemCache::class]) abstract class ItensDataBase: RoomDatabase()

my solution is annotation on database and injection of this, check your tree of files with dependency injection if you forgot anything
