Dart on Android could be nice, I remember Mottier had a blog entry exploring this possibility - http://cyrilmottier.com/2014/06/12/shaping-the-future-of-and...

This being said, I wouldn't expect Google to make any moves towards supporting Dart on Android, or in Android Studio, for that matter.

I'm not sure if they see much future in this project, given that they decided against integrating Dart VM into Chrome.
