So either use `apply plugin 'android-library'` (similar to how I've done it on the KeenAndroid repos pull request).
Or I recommend `providing` the resource from maven like `provided 'com.google.android:android:4.0.1.2'` 
You don't build against the latest version, but at least you don't require the user to install the android sdk, either way this is pretty fragile at the moment.
_worth noting that the android dep in maven is just a stubbed api, so its relatively small_
