    Can you report this as bug.
    Your application is using AndroidJavaProxy somewhere and a crash happens when Java side of it is garbage collected.
    Perhaps you have any additional details on when this happens? Like, is app sent to background when this occurs?

    Unfortunately, I do not know when this happens and why. Also we cannot repeat :(

    Hello.

    We've also faced that issue; in cooperation with our automation team we caught a reproduction of the same crash in the amount of ~1 crash by about 100-200 application runs.

    After some investigations we've decided to turn off AppCenter SDK and, well, crash dissapeared (even after ~800 of application runs).

    Also, we've discovered that AppCenter's AndroidJNI calls are executing without AndroidJNI.AttachCurrentThread usage, contrary to the Unity documentation.

    https://docs.unity3d.com/ScriptReference/AndroidJNI.AttachCurrentThread.html
