In part 2 of the Dagger 2 tutorial, we will add the google/dagger dependencies to a new Android Studio project (for now we ignore the dagger.android classes) and then start learning how to use the Dagger 2 API.

We create a new Java interface MobileComponent, that we annotate with @Component and which has 1 method getMobile declaration that returns our requested fully instantiated object. Dagger will then at compile time generate the implementation for this so-called provision method so we can use it in our activity. In order for this to work, we have to tell Dagger how to create all the necessary dependencies. One way of doing this is with the help of constructor injection, for which we have to annotate all the constructors Dagger has to know about with @Inject.

Dagger will then internally generate a directed acyclic graph (DAG) that contains all the dependencies in the correct order. For this, it doesn't use any Java reflection like earlier dependency injection frameworks

We will also see from where the name dagger came.
