Hi guys simple question, when I import the android module how can I retrieve, for instance, a SharedPreferences ?

bind<Foo>() with provider {Foo(instance()) }

where my Foo class requires in the constracture shared preferences

I add the module in this way:

kodein.addConfig {
            import(androidModule)
            BaseAppComponent()
        }

instance() should be enough to inject SharedPreference into Foo. What are you experiencing?

[mariodroid]

it wasn't working cause I have a ConfigurableKodein
so I had to add the import by :
kodein.addImport(androidModule) instead.. I just figured out it later, although the import it's done successfully it's not working anyway .. for instance to retrieve Resources or SharedPreferences
I got

com.github.salomonbrys.kodein.Kodein$NotFoundException: No provider found for bind<Resources>() with ? { ? }

but in the list of binds I have

bind<Resources>() with factory { Context -> Resources }

which should be enough since I retrieve the instance through kodein.instance()

[mariodroid]

I don't get it..

[Andreas Sinz]

@mariodroid alright, so Resources is bound with a factory that requires a Context as an argument. So you'd need to provide an instance of Context to retrieve the Resources. You have two ways to resolve this problem. Either use instance(context) to retrieve Resources or use kodein.addImport(autoAndroidModule(context)) and then instance() like you did before

[mariodroid]

umh yeah that makes sense I finally get the difference now
I'll try as soon as I get back to work thanks

[mariodroid]

it all works good

[mariodroid]

I was expecting in the case I need a context instance that kodein with autoimport would return me automatically the context from the app. I solved adding it to my component :
bind<Context>() with provider { App.context!! }

[mariodroid]

is there a better way?

[Andreas Sinz]

@mariodroid you can use autoAndroidModule(context) instead of the androidModule, that automatically binds the Context and a lot of other stuff https://github.com/SalomonBrys/Kodein/blob/734f09ba0e8d80046beec92f29c928b46a4dfd23/kodein-android/src/main/java/com/github/salomonbrys/kodein/android/AndroidModule.kt#L212

[mariodroid]

I did that

[mariodroid]

it works perfectly

[mariodroid]

but not in the case I need a instance of Context

[Andreas Sinz]

@mariodroid inside your kodein module or inside your code?

[mariodroid]

inside my kodein Component

[mariodroid]

I had to add this

fun Kodein.Builder.BaseAppComponent() {

        bind<Context>() with provider { App.context!! }
}

[mariodroid]

in order to retrieve the context

[mariodroid]

so now something like this bind<AuthManager>() with provider { AuthManager(KodeinSharedPreferencesInfo(instance(), SP_AUTH).getSharedPreferences()) }

[mariodroid]

can actually work
