Take a look at Eric's (from squareup) presentation material from Oreilly's AndoridOpen Conference last year in his lecture titled Beautiful Android It has a ton of info that should help you out.
I wish they had the video of his presentation somewhere. I could not find it. So sorry.
EDIT : Thanks to @mykola for the yt link
