Using Dependency Injection with Roboguice?

I'm working on an Android project and I would like to know any recommendations about what's a good architecture to build an android application.

I want to use dependency injection using Roboguice and I've been reading about MVVM pattern or MVC pattern (Android MVVM Design Pattern Examples).

Also I know that roboguice have a pretty cool Context-Based Event's raising and handling feature that could be very testable as the code is decoupled.

Any recommendations on a working design pattern? a testable and scalable architecture you have worked with or developed?
