The game works fine in the first few runs but starts to lag afterwards. The error in Android Monitor is like this:

The last part indicates that there is a memory leak in google gms service. I have been searching the web for weeks now, but cannot find out what I am doing wrong

Answer 1

The stackstrace you posted does not seem to have a reference to AndroidLauncher.java. It looks like things go wrong in another part of your code.

The log says at the end

'Internal data leak within a DataBuffer object detected! Be sure to explicitly call release() on all DataBuffer extending objects when you are done with them.'

Do you use any DataBuffer extending objects?

Answer 2

问题是我试图多次调用unlockAchievementBeginner（），这可能导致太频繁的垃圾收集，从而导致游戏延迟
