dagger

问题 Can any please provide example code to achieve this scenario using sub components. In MyActivity i need to fulfill dependencies from multiple components. As you can see in below code MyActivity requies injection from compA via module classA and compB via module classB . @Component(modules = classA.class) interface compA { void inject(MyActivity target); } @Component(modules = classB.class) interface compB { void inject(MyActivity target); } I have been trying many different things for quite

问题 I want to use dagger (dagger v1 by Square) to create a singleton class whose constructor requires context as an argument. I then want to inject this singleton class into my MainActivity. What are the proper steps to define this? I tried doing this: SingletonClass: @Module( injects = {MainActivity.class} ) @Singleton public class SingletonClass { ... @Inject SingletonClass(Context ctx) {} } to which I receive the error: no injectable members on android.content.Context I understand that

问题 The issue that I'm facing is that I want to have two independent scopes that don't really fall into a parent-child hierarchy. In my case, I want two types of scopes: 1) "Feature" based scopes. e.g., when a user enters a feature, a scoped component is created. When the user leaves that feature, that scope is destroyed. 2) "Activity" based scopes (this is for an Android app, sorry about the terminology if you don't use Android). When an activity is created, a scoped component is created. When

问题 Why do I have to annotate a Dagger component with the scopes it's going to use? Why is it not enough to annotate the class itself? 回答1: Because scopes by themselves don't mean anything. It's the components and their relationships that introduce meaning to scopes. Unscoped objects can be provided from any component if their dependencies are available. Since they are unscoped there will be a new object created every time that you call their provider. A scoped object will share the lifecycle of

问题 The error I have is following: Caused by: java.lang.IllegalArgumentException: No injector factory bound for Class. Injector factories were bound for supertypes of MyActivity_: [MyActivity]. Did you mean to bind an injector factory for the subtype? As I understand it happens because I am using an AndroidAnnotations library. AppComponent.class : @Singleton @Component(modules = { AndroidInjectionModule.class, AppModule.class, ActivityBindingModule.class }) public interface AppComponent extends

问题 I am learning dagger dependency injection(I know i am late to the party, its better to start now). But I am facing below error. Please any help or suggestion could be greatly appreciated. ERROR Log error: [Dagger/MissingBinding] [dagger.android.AndroidInjector.inject(T)] @com.mypackage.di.key.ItemDetail java.lang.Integer cannot be provided without an @Provides-annotated method. public interface ApplicationComponent extends AndroidInjector<RetailShopApplication> { ^ @com.mypackage.di.key

问题 I have a Gradle app with a project structure similar to Jake Wharton's u2020: /src /androidTest /debug /main /release In my application class I build the Dagger graph and inject it: MyApplication extends Application { ... public void buildObjectGraphAndInject() { Object[] modules = Modules.list(this); mApplicationGraph = ObjectGraph.create(modules); mApplicationGraph.inject(this); } ... } Inside the debug sourceset, I define Modules.list() as: public final class Modules { public static Object

问题 i'm trying to use Dagger 2 into my apps but i'm having some problems regarding the entities repository and i haven't figured it out what i'm missing. Here is my Application Component: @Singleton @Component( modules = { AndroidModule.class, RepositoryModule.class } ) public interface ApplicationComponent { void inject(AndroidApplication app); IDependenceyRepository dependencyRepository(); } My modules: @Module public class RepositoryModule { @Provides @Singleton IDependenceyRepository

问题 Last week, while implementing Dagger in my current Kotlin MVP project, I was testing it on oldy phone with KitKat 4.4.2 (yep, it still supports all major material features and stuff :)) due to primary phone's maintenance. So that week I was having typical issues rather than something unusual and fixed them more or less quickly by investigating provided errors. At long last, code compiled, current project version was built without issues and ran without major bugs on KitKat with UI interacting

问题 I'm working in an Android project where I'm using Dagger for dependency injection. I don't know so much about Gradle, but as far as I understand, the Dagger annotations are processed by its compiler once the project is built. There's no problem in configuring it as the user guide says. Well, now I want to integrate AspectJ too, so I'm looking at one of the plugins for Android. However, it seems this plugin does a build post processing job to read the aspects too, which remains in conflict
