someone can help? think you

 

@Tomas1856 my app is not build with app bundle , i not sure it is the same issue

 

the crash is only crash in this api levels:

Android 4.1.2,level 16 and

Android 4.2.2,level 17

Android 4.2.1,level 17

 

Same problem, started just recently, getting crashes on lower android api levels. Setting "Force Internal" does not help. Have you found a solution?

 

Found a solution: turns out the problem was in IL2CPP, building win Mono was fine. And I fixed IL2CPP build too, all I needed is to uncheck "Strip Engine Code" checkbox.
Unity version - 2019.2.9f1

 

Im getting that exact same error in production as well for Android 4.1 (not sure if other Android versions)

EDIT: I didnt try to remove yet the Strip Engine Code to see if it fixes, will write again after more tests

 

Unchecking Strip Engine Code solved the problem for me as well

 

I created an empty project using LWRP template, changed to IL2CPP/.NET 4, almost everything else default, tried to run on a 4.1 device and it crashed. Unchecked Strip Engine Code and it worked.

Im on Unity 2019.2.9f1

 

It's just an empty project, I cant see how this missed QA. In any case I have created the bug report (case 1193070).

 

Setting "Force Internal" does not help as well for me，i will try the Unchecked Strip Engine Code method

 

I experienced the libunity.so failed to load on il2cpp android builds on 2019.2.9f1-2019.2.11f1.

2019.2.8f1 works fine. mono builds work fine. will investigate the strip engine code setting now.

 

in 2019.2.11f1, unchecking strip engine code does produce an il2cpp android build that does not crash on boot. it is 4665kb larger than the build with stripped engine code, however.

 

we've submitted a bug report with logs and repro steps and all that and are back to using 2019.2.8f1 for the immediate future.

 

we see a different crash on boot when stripping engine code on il2cpp builds in 2019.2.14f1.

we do not have unitywebrequest package enabled as we do not use it. we also do not touch cloudjobs, whatever those may be. no other build configuration that we have tested crashes on boot like this.

we are sticking with 2019.2.8f1, that appears to be the last version that produces stable android il2cpp player builds.

 

incase anyone cares, stripped engine il2cpp android builds still crashing on boot in 2019.2.18f1. we are still using 2019.2.8f1

 

We are also on the 2019.2 stream and trying to fix a crash for our users on lower Android API levels. Trying out this fix now, should know in a few days if it helps.

 

@herb_nice are you able to disable stripped engine and move up to 2019.2.18? This is the current test I am running and deploying to users now

 

no. we tested 2019.2.18f1 back in january and it was still broken so we are still on the last known working version, which is 2019.2.8f1.

 

thank you its working now.
