In Android apps using Dagger 2

Answer 1

With 1 and 2 you are using static references. This is a good thread about why to avoid them

Why are static variables considered evil?

So the only option left is the 3rd. That is what I am using on my projects. About if you should pass the context as argument or not, depends on the architecture of your project and how you designed the Dagger dependencies. Personally I don't have that problem because I am only injecting in Activities/Fragments. Can you give me an example where you need to pass the context to inject dependencies?
