Android Export failed at 75% ("Packaging Failed")

Hi All,

New GDevApp user here. I’ve tried to export the Endless Runner example game to Android. The export process failed at 75%. It is failed at this step: “Prepare for the packaging…”

Screenshot of the error:

As you can see the error screenshot is not really helpful in telling me what it is that went wrong. So need your help here.

EDIT: Additional information that might be useful. I’m using Mac OS X 10.9 (Maverick?) with Firefox v.42.
