In part 3 of the Dagger 2 tutorial, we will learn how to do field injection. By annotating a non-private, non-final member variable with @Inject, we tell Dagger to set its value by referencing it directly. Field injection is mainly used to inject variables into Android framework types that the system instantiates and on which we can't do constructor injection, like activities, BroadcastReceivers and fragments.
To trigger the injection process on an already instantiated object (like an activity), we have to create and call a members-injection method in our component that takes this particular class as an argument.
