LibGDX project written in Scala, on Android, using IntelliJ

So I've been working on a LibGDX project in IntelliJ v12.1.6 using Scala after getting set up using this tutorial: http://www.gamefromscratch.com/post/2013/12/01/Using-LibGDX-with-IntelliJ-with-Gradle.aspx. However I've noticed, when testing the game on my android device, I receive the following error

12-04 17:46:22.483: ERROR/AndroidRuntime(18951): FATAL EXCEPTION: GLThread 475

    at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1240)

Whenever I attempt to utilize a method that's native to Scala (such as the standard println() method).

I suspected that the android class could not find the classes utilized by Scala, so I attempted to export the android project with the Scala library. Whenever I try this however, I get an error that I have too many methods, (similar to this) which would make sense as Scala introduces well over enough methods into the project to warrant this error.

My question is how could I make the android project aware of the Scala classes and methods, so that I could use them as effectively in the android project as I have been able to in the desktop project?

Thanks!
