  • We also tried solutions given in below Post to add "android.bundle.enableUncompressedNativeLibs=false" in Custom gradle template ,but nothing worked for us.
    Ref Link : Native method not found: com.unity3d.player.UnityPlayer.nativeRestartActivityIndicator:()V page-4

  • We have tried to backtrace this error log with the stack trace utility provided in the Android Logcat V1.2.1 Package, but every time it returns symbols missing.
    We have tried to attach symbols from bellow locations but nothing worked for us

  • Unity\Hub\Editor\2019.4.20f1\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\il2cpp\Common\StaticLibs

  • Unity\Hub\Editor\2019.4.20f1\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\il2cpp\Development\Symbols

  • Unity\Hub\Editor\2019.4.20f1\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\il2cpp\Release\Symbols

  • Unity\Hub\Editor\2019.4.20f1\Editor\Data\PlaybackEngines\AndroidPlayer\NDK\platforms<Android API>\arch-arm64\usr\lib

  • Symbols Generated on AAB build path

  • ProjectFolder\Temp\StagingArea\libs\

Please Provide solution if you have any for the below questions

  1. Does unity provide any symbols on any other location which is useful in this type of scenarios?
  2. Is anyone facing same type of crashes in android with 2019.4.20 Version?

Thanks in advance.

Since you’re using il2cpp probably with Strip Engine Code On, the symbols for libil2cpp and libunity should be in zip package next to your app bundle, please use that to resolve stacktrace.

Thanks @Tomas1856 for quick reply.
We’ve already tried with symbols located in zip package next to our app bundle
but it didn’t worked
Is there any other solution that we can try ?

Same issue here! Android Game crash on start. No game version update. The latest version has been online for a week. Suddenly crashes report on firebase from yesterday. We are using 2019.4.21. Anyone know why?

What exactly didn’t work? Resolving stacktrace is the first step in solving such problems, without this information, it’s hard to move forward.

If you see something like this in your crash’s call stack: [anon:libwebview reservation]

Your crashes are related to the bugged WebView update Google did yesterday. Players must update their Android System WebView on the Play Store. We had a ton of crash, out of nowhere since yesterday.

I was hoping that we could do a client fix to prevent this, but not sure it’s possible.
