Problem Building in Release Mode

[SubutaDan]

I am unable to build my Flutter app. that uses social_share in Release mode. I am getting this message:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':social_share:verifyReleaseResources'.
> A failure occurred while executing com.android.build.gradle.tasks.VerifyLibraryResourcesTask$Action
   > Android resource linking failed
     ERROR:/Users/dan/git/kokodoko_flutter_client/build/social_share/intermediates/merged_res/release/values/values.xml:194: AAPT: error: resource android:attr/lStar not found.

When I try to build in Release mode I also get numerous error messages about a Kotlin version incompatibility, for example:

e: /Users/dan/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlin/kotlin-stdlib/2.0.20/7388d355f7cceb002cd387ccb7ab3850e4e0a07f/kotlin-stdlib-2.0.20.jar!/META-INF/kotlin-stdlib.kotlin_module: Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.9.0, expected version is 1.6.0.

I think the two are related, but I don't know for sure.

I have done some googling and tried some recommended fixes and workarounds but have not been able to execute the build in Release mode.

I think this problem may have begun when I upgraded Flutter, but downgrading doesn't seem to resolve the issue.

Anyone else encountering this? Any suggestions for resolving?

Thank you for your help.

Adding this into android/build.gradle solved it for me

subprojects { afterEvaluate { android { compileSdkVersion 34 } } }

(if you have some existing subprojects blocks, make this one be the first)

Here's a comment I found that explained it in more detail: transistorsoft/flutter_background_fetch#369 (comment)
