My suggestion is create variables on Android build files to package standalone games, like suggestion in those issues https://github.com/EasyRPG/Player/issues/995 and https://github.com/EasyRPG/Player/issues/1085. I modified this project in my computer, to create a Android package to auto start a game and it's works on my smarphone and it run, except audio (I beleave that an error has occurred when I executed the script and I not see it).
