Port Android App to Desktop?
I'm just wondering if it would be possible (and legal) to port an Android app to desktop? I'm creating an android game that would work well on PC too (even with the cellphone like layout) and was thinking that maybe I could 'embed' an android emulator with an installer or would that process be a bit hard for a novice Java coder? ...
