Do you know how to program in javascript? In that case, you may want to try unity. They are able to save android files. Also, eclipse is a good javascript editor that you can save documents for android app store. I have encouraged C2 to allow games to be exported to the android app store as I am an android developer as well. So yeah, unity would be the way to go. However, if you have no javascript experience than tough luck :(! Also, how did you even export your project to the app store?? I can't seem to even be able to do that!
