Dagger 2

My YouTube videos:

Brief Explanations

@Module class - "Dagger, this is how to create my dependencies"
@Component class - "Dagger, these are my @Modules, please build the dependency graph"
@Inject constructor - "Dagger, please use this constructor to instantiate this class"
@Inject field - "Dagger, please set this field for me"
AndroidInjection.inject(this) - "Dagger, please inject this class's fields now"
@Singleton in a @Module - "Dagger, please only create one instance of this dependency" (be sure you know what your're doing when using this)
