Only issue in Android 7.0 (java.lang.ClassNotFoundException)

Unity Engine

Hi.
Recently, I released the game.
However, an abnormal termination occurs randomly.
Most of it also happens on Android 7.0.
A few days, I can not solve it.
I’ll be waiting for your reply.

Is this something you’re seeing yourself? or you’re getting reports from users who are trying to play the game ?

Did you get this figured out? I am having the same issue

Not sure what the issue is, but worth checking what models it happens on, and also to verify that this class is indeed included in the .apk

any update i’m facing the same here

@wafer23 can you verify that this class is included in your built .apk ?
