    Alright, setting up Jacoco the right way is massively confusing.
    Normally, you'd use something like additionalClassDirs to add the folders you need.
    However, we want to exclude the android/ folder, and likely will need something else
    in the future. In order to do this though, we need the doFirst block. See SO here:
        http://stackoverflow.com/a/17411305/1454178

    Additionally, to properly exclude, we need to run that code outside the doFirst block.
    No clue why this is, but please don't change this without extensive testing.
