I have been coding my libgdx application (for desktop only) for a while and after deciding to cleanup the code part by part iv'e gotten into a problem i cant seem to solve myself..
exception:
Exception in thread "LWJGL Application" com.badlogic.gdx.utils.GdxRuntimeException: java.lang.UnsatisfiedLinkError: com.badlogic.gdx.physics.box2d.PolygonShape.newPolygonShape()J

after googling for a while i figured my error is as mentioned in this thread as in
Another problem might be that you instantiate a SpriteBatch (or something else which internally uses a SpriteBatch) too early (looked a bit like this in the stacktrace).
but as the answer mentions
Instead, create such things in the create/show methods of your game.
I cant seem to understand when libgdx is initialized and ready for use, and where to place my GameUtils.init() method to assure libgdx is initialized
My code is as follows: (i have taken out e-relevant methods)

Help is much appriciated! :D
