app stopping on device.

Hi!! Just trying out Gideros for the first time. Trying to build for my android device and the app starts but just stops before showing anything on the phone. The app builds perfecly on the simulator. Im not sure if this is a Gideros issue or an eclipse/java version issue. The logcat looks like this:
