Font rendering on Android is bulky, blocky, and fails to consider how humans read letterforms. So, even if a designer can convince the team to license a better font, it’ll end up a smeared mess on users’ screens.
The API calls to layout type on Android suck. (iOS sucks slightly less depending on how willing your UI engineer is willing to devote to this most basic foundation of design.)
“U MAD, BRO?”
Yeah. I get paid to be a picky snob about what the user sees and how they feel about the product. It pisses me off to look at Android because its not disappointing, the way Win8 is, but actively anti-design. Why pay to license good fonts? Why make a system for rendering type nicely? Because this stuff is basic user experience. It's like going into a hotel and discovering that the paint is yellowing. That hotel is more likely to have dirty towels, no hot water, smelly sheets, and bed bugs.
