dagger-2

I'm currently experimenting with InstantApps and would like to include dagger into my project. I'm facing an issue setting up an application AppComponent. My application component includes all the feature dagger modules of my app. I basically have: One Base app module containing my Application class Multiple features with each a dagger Module per Activity, all with Base as a dependency. One app module and instant module both importing all the features and the base app module. I'm trying to figure out the setup before adding the Instant App module. From InstantApps documentation and project

I'm playing with Dagger-2 to figure how to integrate it in our existing application and I'm facing something which I can't understand or I'm doing wrong. My situation : 3 API without any annotated constructor ( each one in its own file ) public class DbApi { public void doSomething(String username, String password) { } } public class RestApi { public void doSomething(String username, String password) { } } public class SocketApi { public void doSomething(String username, String password) { } } 3 Modules ( each one in its own file ) @Module public class DbModule { @Provides @Singleton public

I just started using Dagger 2 and I found online thousands guides each one with a different implementation and I'm a bit confused now. So basically this is what I wrote at the moment: AppModule.java: @Module public class AppModule { Application mApplication; public AppModule(Application application) { mApplication = application; } @Provides @Singleton Application providesApplication() { return mApplication; } } DataModule.java: @Module public class DataModule { private static final String BASE_URL = "http://beta.fridgewizard.com:9001/api/"; @Provides @Singleton NetworkService

According to http://konmik.github.io/snorkeling-with-dagger-2.html i could just add inject(Anything anything) into AppComponent.java, but this doesn't work for me, in the articles example: @Singleton @Component(modules = AppModule.class) public interface AppComponent { void inject(MainActivity activity); void inject(MainFragment fragment); void inject(MainToolbarView view); } If I try to inject dependencies into my fragment the injected members remain null. What obvious error am I missing here? Relevant sources: ApplicationComponent.java @Singleton @Component( modules = ApplicationModule.class

How would I create an instance of Dog with a component which provides Cat. public final class Dog { private final Cat mCat; public final static String TAG = "Dog"; @Inject public Dog(Cat cat) { mCat = cat; Log.e(TAG, "Dog class created"); } } After experimenting with Dagger 2 for a while I have no idea how to use constructor injection – a hint would be nice, thanks. Edit: Whats wrong with the question? After using Dagger 2, following several tutorials and reading the official documentation I have no clue how to use the constructor injection feature, that's why I ask here. Instead of injecting

I was kind of lazy and used to use almost entirely field injections. I was just providing empty constructor, put my @Inject fields I everything was looking nice and simple. However field injection have its trade-offs so I've devised some simple rules that help me to decide when to used field and when to use constructor injections. I will appreciate any feedback if there is mistake in my logic or if you have additional considerations to add. First some clarification in order to be on the same page: Constructor injection: @Inject public SomeClass(@Named("app version") String appVersion, AppPrefs
