dagger-2

问题 We have a huge codebase to migrate from dagger 1 to dagger 2 but we would like to do it step by step. For that we were thinking to have both versions as our project dependency and do the migration module by module. But we were unable to make it work. This is the article we referred https://fernandocejas.com/2016/08/03/android-dagger-1-and-2-living-together/ but without any luck or is there any other way? Thanks. 回答1: There's no other way.

问题 Okay, let's make this simple. I have created a simple library called my-network-library with two classes in it. First one is a Hilt module called BaseNetworkModule @Module @InstallIn(ApplicationComponent::class) object BaseNetworkModule { // Client @Singleton @Provides fun provideOkHttpClient(): OkHttpClient { return OkHttpClient.Builder() // my default okhttp setup goes here .build() } } and the second one is a simple class. class MyAwesomeClass { fun doMagic() { // magic code goes here } }

问题 I want to add a callback to the room database to populate initial data. @Provides @Singleton fun provideRoom(context: Context): MyRoomDatabase { return Room.databaseBuilder(context, MyRoomDatabase::class.java, "my_database") .fallbackToDestructiveMigration() .addCallback(object : RoomDatabase.Callback() { @Override override fun onCreate(db: SupportSQLiteDatabase) { super.onCreate(db) } }) .build() } For that i need the database instance in the callback to access DAO for inserting data. How

问题 How is @Named used with @BindsInstance? I have the this component interface AppComponent : AndroidInjector<MyApplication>{ @Component.Builder abstract class Builder : AndroidInjector.Builder<MyApplication>() { @BindsInstance abstract fun preferenceName( @Named("PreferenceName") name : String ) : Builder } } and trying to inject in MyApplication @Inject @Named("PreferenceName") lateinit var prefName : String But it fails with MissingBinding for String. I could resolve this with a module

问题 I am facing an issue while implementing MultiBinding using dagger 2.2. I am using dagger with MVVM architecture. I have injected the ViewModelProvideFactory constructor and binds the dependency from module. I have followed the tutorial of Mitch from youtube https://www.youtube.com/watch?v=DToD1W9WdsE&list=PLgCYzUzKIBE8AOAspC3DHoBNZIBHbIOsC&index=13 I have searched on these links for the solutions but still facing the same issue. Dagger2: ViewModel cannot be provided without an @Provides

问题 I am using Dagger2 in my android application, I have two component in my application. First is global for entire application and second is specific to activity instance. NetComponent.java @Singleton @Component(modules = {AppModule.class, NetModule.class}) public interface NetComponent { void inject(AuthenticationActivity authenticationActivity); void inject(PaymentActivity paymentActivity); } ValidationComponent.java @Singleton @Component(modules = {ValidatorModule.class}) public interface

问题 In Dagger, how can I add a model to Module?

问题 I'm trying to inject in my presenter an interactor but gives me an error, at seems I can't inject in a class who injects to another: error: [Dagger/DuplicateBindings] com.example.calculadora.Data.Interactor.Operacion is bound multiple times: @Provides com.example.calculadora.Data.Interactor.Operacion com.example.calculadora.Inject.InteractorModule.provideDiv() @Provides com.example.calculadora.Data.Interactor.Operacion com.example.calculadora.Inject.InteractorModule.provideMult() @Provides
