Sorry, meant to leave those comments (from https://github.com/seatgeek/Android-MultiStateView/commit/39736d6bf1ddcb2dc50ee7944d2f5272db79795a) in the PR, not on your commits.

Why is 19.0.3 necessary?  Would "19.+" be sufficient?  If not using anything introduced in 19.0.3, there's no reason to lock the project in to that version.
