Have you looked at the usage guides for the various plugins [1][2]?

Anyway, even your second link stresses: "The primary IDE recommendation is IntelliJ, not Android Studio nor Eclipse". My IDE of choice is Android Studio, and it not being particularly recommended is a red light to me already. Maybe I'm just traumatized.
I'm surely lazy. I wish Google made Scala support for Android official and integrated it seamlessly.
Seriously? Android Studio is just a stripped down IDEA with an extra plugin anyway. If you already use AS, there is zero reason not to just import your config into IDEA instead.
