I Made a game using libGDX and java. I put it on the android market for free. I'd feel terrible taking money for this game. This is more of a learning experience for me than anything. I need to update it's textures and work on the font among a myriad of other things. I plan to add other obstacles / features as I get inspiration or free time.
You can download it from the play store https://play.google.com/store/apps/details?id=pj.android
