Sorry to hear that.
I may consider learning on making apk files once development of the game is finished, so i only need to make one apk for each of my games. Making a new apk file for each version and update would just be such a immense time effort and I am just a solo game maker. So unfortunately there is not much else I can do-_-
But if someone should contact me who has experince with making apk version and wnats to help out things may change but currently I would not keep your expectations too high.
