I believe this was brought up before, and the consensus was that since GM:Studio Android apps makes use of some sort of C rather than being completely written in Java, repackaging the apps for Blackberry isn't possible.
I will probably try to create a simple one a repackage.
If I recall Blackberry 10 is actually pushing C more than Java. And has been since their OS for their tablet. I'll try it... Hopefully game maker will have a build for it. Cuz looking at the news Blackberry is making a combat and alot of businesses are getting behind BlackBerry 10 devices.
