Hi!
Do you have any other game that is running on the rpg maker MV engine on your device? If so, that might be why.
The tools offered by this engine to support Android are severaly outdated, and I struggled a bit to find a way to make it work, to the point where I was not sure I would be able to release it on Android at first. The way I used to make it work seems to make it so any game that used the exact same method will be considered "the same game" even though it is not.
Please let me know if that solves your problem.
