I don't want this to turn into a god class. We can definitely take out the constants and the accents and put them into their own file (or files). Will make things a lot cleaner.

We don't need yet another RecyclerView, right? ;)

I agree, it would be better to split that into smaller files. It'll maker easier to read and maintain.
