I want to add Leaderboard in the Android studio for store game score.
What have you learned so far about doing this? Have you done any research with Google at all?
Thanks for replay. Yes, I was learned from google doc but I got an error like Fail to sign in. Please check your internet connection. I think this because app Id does not connect to leaderboard Id.
then other users will not be able to log in. perhaps it was a mistake? check in the settings, maybe you blocked it?
