I started making a semi-complex android app as my first project. Saw the recommendation to use fragments, and I have never looked back because I am way, way too far down the rabbit whole. It's main advantage to me is perhaps nothing. I have no idea and no real way of knowing. But is has tripled my code base, so that is a good thing!
