either pass them as param or add them to same module, or provide them in upper module namespace

Hi there. I'm having some serious performance issues with Koin on Android. When I open a new activity the main thread freezes for about 7 seconds while resolving injections. Has anyone seen something similar?

can I pass properties to it?

To take the example in https://insert-koin.io/docs/1.0/documentation/koin-core/index.html#_binding_additional_type, if I had the following:

// Service interface
interface Service{
    fun doSomething()
}

// OtherService interface
interface OtherService {
   fun doOtherThing()
}

// Service Implementation
class ServiceImp() : Service, OtherService {
    fun doSomething() { ... }
    fun doOtherThing() { ... } 
}

How could I write my module definition such that the

single

ServiceImpl

is bound to both

Service

and

OtherService

?

@arnaud.giuliani can you please help me with question about dependencies: as I understood every dependency that can be requested from Koin should be explicitly defined in Koin definition? Meaning there is no implicit constructor injection like it is in Dagger?

hi, I’m new to koin, this is my first attempt to set it up. but it does not work. my dependencies are wery simple:

class PWApp: Application() {

    private val appModule = module {
        single<AuthRepository> { SecureAuthRepository(get()) }
    }

    override fun onCreate() {
        super.onCreate()
        Stetho.initializeWithDefaults(this)
        startKoin(this, listOf(appModule))
    }
}

but it can not resolve reference for

join()

. Android Studio does not suggest any imports so I looked up examples and copy/pasted imporr from there:

import org.koin.android.ext.android.inject

But this method does not suits my case:

Unresolved reference. None of the following candidates is applicable because of receiver type mismatch:

public inline fun <reified T : Any> ComponentCallbacks.inject(name: String = ..., scope: Scope? = ..., noinline parameters: ParameterDefinition /* = () -> ParameterList */ = ...): Lazy<AuthRepository> defined in org.koin.android.ext.android

I have no idea what to try next. Could someone please help me with this ?

Hi all, new Koin on Android user here. In Dagger, I would create a Singleton AppComponent Room Database which I would prepopulate in

.addCallback(object : RoomDatabase.Callback() { override fun onCreate(db: SupportSQLiteDatabase) ... }

. So by the time I needed to use the data inserted, it was there. With Koin, my DB is declared as a

bean

and it gets created lazily so first time I access the database, 0 items is returned, coming back to that screen again renders all of the items. I tried initializing the DB in my Application.onCreate() but the the database's onCreate() does not get called. Any ideas what can be done? My thinking is I need to somehow create the database and its data before it's first accessed (as opposed to how Koin is designed to access dependencies lazily when they are needed by that particular screen). I doubt this part is relevant but I use Google Arch Paging component to load data.

Hello, New on Koin, it's reallyan amazing tool to work with, compare to the complexity of gradle. Love it so far. But, while trying to work on unit test, i've end up with the following problem. My viewModel can't be created and the error message is just "nul" so... i'm a bit lost on how to solve it 😕 Here my repo https://github.com/soundlicious/RatLab for cloning.

@cristiangm I’m on it 👍

I will need people to help test it also

Koin

1.0.2

published 🚀 - changes available here: https://github.com/InsertKoinIO/koin/blob/master/CHANGELOG.md

@Vinicius Volpe one of the next subject is kotlin compiler plugin to help generate module with @Single @Factory or @Scope

So like in gradle, say module A had all the tests and injections written. module B would be able to add its modules and then run all the tests without copy pasting everything

Hi, is it possible to use the experimental builder with an injection parameter?

?

fun <T : ViewModel> Fragment.sharedViewModelByClass( clazz: KClass<T>, key: String? = null, name: String? = null, from: ViewModelStoreOwnerDefinition = { activity!! }, parameters: ParameterDefinition = emptyParameterDefinition() ) = viewModelByClass(clazz, key, name, from, parameters)

@arnaud.giuliani is the website out of date? There are some typos that were fixed 2 months ago, but not yet on the website.

That's what I'm trying to do now with gradle. No luck so far.

what does koin android do on top of regular koin?

@Alan Evans Same API but koin-core has been entirely rewritten

Does anyone have any examples of using Koin to inject an exposed Database instance? or would that be a misuse? Decided to try kotlin (coming from scala, etc) yesterday and can't figure out how to use this library.

DSL For declaring your Koin application, deprecated API drop, stabilize Scope & Testing API

Hi! We’ve just added Koin to our project and we are facing the test part. We’d like to substitute a provided dependency with a mock in an android test. How should we do it?

will switch to version 2 probably today so yes 😄 just wanted to get some ideas on what would be the best approach on this when your app module doesn't know about the dynamic module

Hello guys. How can i inject the activity view to the presenter? i have found only this solution on internet

presenter.attachView(this)

nop, Koin doesn’t do any reflection to guess your dependencies. Koin deals with your declared types

What would be the cause of this error?

Can't access ViewModels from detached fragment

EDIT: I fixed it by using

by viewModel()

instead of

= getViewModel()
