android ver2.1.6 is now available

Fixed display bugs

This is something that we made private last November and has moved forward a lot in the past 7 months, and we are squashing the internal display bugs one by one as we go along.

Update internal library

We are also gradually updating the library we were using here, which I think is a lot of fun, as Android often requires subtle tweaking.

We are desperate to catch up to the latest one step ahead in the next few weeks.
