I think sans-serif-medium was added in Lollipop so the text looks thinner on Kit
Kat. Not sure if there's anything we can do about this. I suppose I should use
sans-serif in the v17 file just so we're not using an invalid option (it still
looks thin)

It turns out that android:attr/colorAccent was added in API level 21 so this
crashes on Kit Kat. I could hard code a color here but right now e.g. we have
different colors in Chrome (green, which I think is the default) and Gmail
(blue), so it'd be nice to still support this. I guess I'll provide a separate
version of this file for v21?
