Official IL2CPP Build Time Improvements - Seeking Feedback

I could build for Android using Master compiler after changing Stripping Level to Medium (I was using Low) and switching from .NET Framework to .NET Standard 2.1. Details below:

•Unity 2021.3.9f1
•Faster runtime
•Compression: LZ4HC
•API Compatibility: .NET Standard 2.1
•Compiler Configuration: Master
•All architectures (ARMv7, ARM64, x86 and x86-64)
•Managed Stripping Level: Medium/High
•I also removed some unused scripts from project.

Build completed without any errors.

Hope it keeps working and maybe that helps someone.

 

Thank you, @pradotech .

Any differences with other levels and compiler settings (like apk/abb size, on device performance)?
Can't test myself on Unity 2021.3.9f1, cause there is a crash on launch

 

I didn't try other settings after I found this working one, but I'm almost certain that the managed stripping level on low is the main reason for the build errors.

 

OMG THANK YOU SO MUCH!!!
This was driving me crazy for the past week... suddenly my project couldn't be build anymore, but this does seem to work!

 

hello i'm having an issue with Generics & IL2CPP with Unity 2021.3.11f1

i'm trying to use YoutubeExplode which depends on System.Text.Json

https://www.nuget.org/packages/YoutubeExplode/6.2.5#dependencies-body-tab

but i keep getting errors related to missing methods when use IL2CPP (both .NET standard 2.1 and .NET framework paths)

https://github.com/Tyrrrz/YoutubeExplode/discussions/679#discussioncomment-4639222

i tried adding a link.xml, and disabling Strip Engine Code, and low / disabled stripping levels, to no avail

NOTE: when i switch to Mono scripting backend, it works. But then I can't target ARM64 / v8a

which means i can't publish to google play https://i.imgur.com/BoBXowU.png

any suggestions or guidance would be greatly appreciated

**UPDATE**


derp, i was still on unity 2021

i've upgraded to Unity 2022, to take advantage of Full Generic Sharing,

but now I have a new error:

1. K:\Code\Nreal-Unity-Demos\Android\unityLibrary\src\main\Il2CppOutputProject\Source\il2cppOutput\System.Text.Json3.cpp(11890,11): error: no viable overloaded '='
2. V_3 = L_12;
3. ~~~ ^ ~~~~
