I just finished my game and implemented google play games services and everything works well as an apk file . But if I want to export it as an Android app bundle file, the file size is a lot smaller (got from 38mb to 16mb), but the Google play games services does not work anymore . Any ideas for what could causes the problem?
But the game is already downloadable from the google play store. It would be awesome to get feedback for it as well.
It is about localising sounds just by listening over stereos headphones and centering them in the middle by tapping on the left or right half of the screen.
