Code cleanup

[Jawnnypoo]

This is mostly just cleanup of lint errors found by Android Studio in the project. I tried to break up the commits by the type of lint error it was, but some commits cover a few things at once

I don't really think there is anything I can do about that first failure on codecov

[flovilmart]

Nah not really, but this is OK, as we don't require the status to merge.

[Jawnnypoo]

@rogerhu Is there something blocking this?

[rogerhu]

Nope I think the review required stuff throws me off.

[Jawnnypoo]

Good to merge now, @rogerhu ?

[rogerhu]

rebase

[Jawnnypoo]

@rogerhu Done!
