java.lang.NoClassDefFoundError (Mix of API levels)

[mustafaozhan]

Hello I saw closed issues with desugaring for Android but my issue seems not fixed with it.

I moved my Android project to Kotlin Multi Platform and current modules for the android project are below:

android -> client(KMP) -> common(KMP)

android doesn't implement kotlinx-datetime directly but client and common has it and uses. When I applied desugaring to only android it didn't work and I applied to all these 3 modules (with Java8 support). this is a branch that you can check.

I just created a build from mentioned branch and published for internal testing (by this way Google runs it in couple of devices)
I have crashes from below android versions

• 5.0.1
• 6.0.1
• 8.0.0 (SDK 26)
• 8.1.0
• 9

Here is the original crash report from Firebase

Thanks in advance!

Same for me

[dkhalanskyjb]

Thank you for the report! I did manage to reproduce the crash when running the release apk in the Android Emulator for 8.0 (the debug apk seems to work fine). Looking into this.

[mustafaozhan]

Ohh actually that's right to be when i was testing it was okay too :) Thanks, as you can imagine it is a release blocker 😓

[dkhalanskyjb]

Could you try explicitly adding a dependency on kotlinx-datetime in android/build.gradle.kts? It seems to have fixed the issue in my small reproducing project.

[mustafaozhan]

@dkhalanskyjb Thank you for checking it 👍 I confirm that i didn't received any error so far, closing the issue
