Target Architecture : ARMv7 (checked) ARM64 (checked)
I am receiving the same error issue "Fatal Exception: java.lang.Error" in my firebase crash crashlytics which is causing my crash free rate to drop below 99% which is very frustrating. I am trying to figure out what the cause is as it’s only affected so far 69 users out of potentially 9,000 users, so it’s a very niche issue and looks like its primarily on low end devices but google was considering featuring us however our crash rate needs to remain above 99% for that to go ahead. The crash rate is steadily increasing with the number of users increasing.
Seems to happen for users when loading application:
Heres one of the errors:

I have searched and seen many users on unity had this issue but didn’t find a resolution. One resolution for someone was to do the following:
PlayerSettings > Configuration > Scripting Backend: IL2CPP PlayerSettings > Configuration > Target Architecture : ARMv7 (unchecked) ARM64 (checked)
As seen in this thread
Native method not found: com.unity3d.player.UnityPlayer.nativeRestartActivityIndicator:()V page-2
However, if I did that would it mean eliminating a large amount of my user base?
I also read this could be a solution?
ABI Stripping
Some AAR files contain native libraries (.so files) for each ABI supported by Android. Unfortunately, when targeting a single ABI (e.g x86), Unity does not strip native libraries for unused ABIs. To strip unused ABIs, the Android Resolver plugin explodes an AAR into a folder and removes unused ABIs to reduce the built APK size. Furthermore, if native libraries are not stripped from an APK (e.g you have a mix of Unity’s x86 library and some armeabi-v7a libraries) Android may attempt to load the wrong library for the current runtime ABI completely breaking your plugin when targeting some architectures.
AAR explosion and therefore ABI stripping can be disabled via the Assets > Play Services Resolver > Android Resolver > Settings menu. You may want to disable explosion of AARs if you’re exporting a project to be built with Gradle / Android Studio.
I would appreciate any help and hopefully in future if anyone else is experience a similar issue this thread can help them out…
