What is actual usage of “HasFragmentInjector” in Dagger 2

Question

I have implemented dagger2 v2.2 previously but as now they have added dagger.android part also. so I am creating sample project with that.

I am aware about old methodolo

Answer 1

Official Documentation explains this topic quite well in my oppinion.

Anyway the main benefit is that instead of something like this

((SomeApplicationBaseType) getContext().getApplicationContext())
    .getApplicationComponent()
    .newActivityComponentBuilder()
    .activity(this)
    .build()
    .inject(this);

You can simply write this, which makes life easier for everyone.

AndroidInjection.inject(this);

1. Less boilerplate, easier maintainability.

2. The previous approach is kind of breaking the basic concept of dependency injection, a class should not know any details about the way dependencies are being injected.
