            Dagger2 dependency injection: How does it work in an android app?
            Asked 2019-Jun-17 at 02:37

            I am trying to understand an example for an app with offline support using retrofit and room:

            You can find the code for it here:

            This project is using dependency injections with Dagger2. I've never worked with it so I am trying to understand how things work together. I understand the purpose of dependency injection but I don't understand the implementation of the project above.

            I found a very good introduction into Dagger2 here:

            A Friendly Introduction to Dagger 2

            Dagger 2 example Code:

            I worked through it and got most of it. Back to the actual project I am trying to understand (link 2). It still doesn't make sense to me and here is why:

            1. The interface AppComponent has one method which is used: public void inject(MainActivity2ViewModel viewModelModule); The return type is void. In the Dagger2 sample project (link 3 and 4) they use WeatherReporter getWeatherReporter(); which makes sense because later they call this method to get a WeatherReporter-Instance and Dagger2 manages all of the instantation process in the background. But I get nothing if the return type is void. Why is the return type not an object?

            2. There is one @Inject in MainActivity2ViewModel:

              @Inject public void setRepository(GitHubRepository2 repository) { this.repository = repository; }

            repository is the only field of MainActivity2ViewModel so it is a dependency. The GitHubRepository2 constructor has 3 parameters:

            There's a lot of comprehensive tutorials about Dagger2 in Android. But I'll show you a glimpse of what it's used for. And minimal usage.

            Ultimately, dagger will use the annotation @Inject which will provide(reference to the object or value) to the variable.

            Injection is usually used on reusable or boilerplate objects like Dao, Repository, ViewModel, NetworkAdapter

            Inject UnitTest classes
            Asked 2017-Jan-20 at 07:54

            Hello I have the following problem using Dagger 2 in my (part) project being completely pure-Java with no android dependencies.

            When I run the unit tests using some mocks (e.g. Injecting a Mock Network Connector returning static Strings) over the Gradle view or console (businessModule:test) there are no problems and all tests Succeed. But when I open the files in Android Studio the Studio says that the Return of my DaggerMockComponent is not compatible with the target type. Opening the generated Component-Implementation, I see that Android Studio thinks the TestUnit-Class (and the interface MockComponent) is not available so it does not know what the inject method returns.

            I have the following gradle file:

            apply plugin: 'java'

            Ok everybody, after an additional night and some research on the android-apt plugin I stumbled over the pure-Java apt (net.ltgt.apt) and now I have a working solution in combination with the idea-plugin
