Nice article!

Comparing to MVP design pattern, I think Loader is the presenter part, with async and life cycle event bound, am I right?

I think that Loader is a really great solution, and it could be combined with MVP pattern perfectly. But I have been using a MVP library https://github.com/sockeqwe/mosby for months, and mosby + RxJava covers the async and life cycle event problems perfectly, but I will give Loader a trail.

Thanks for your sharing!
