Is anyone using Coroutines 1.7.0 with Compose yet? The ui-test-junit4 artifact seems to be using some APIs that were removed (stacktrace in thread)

Try version 1.7.1 of coroutines instead, it specially restored binary compatibility for the experimental APIs that runTest was using: https://github.com/Kotlin/kotlinx.coroutines/issues/3673

[kenkyee]

Thanks! 1.7.1 and Compose 1.4.3 seems to work 🙂

Also, FYI, Compose 1.5.0-beta02 has this error so it needs a later androidx-core than 1.8.0 (looks like we're almost a year behind on that):
java.lang.NoClassDefFoundError: androidx/core/view/SoftwareKeyboardControllerCompat
at androidx.compose.ui.text.input.InputMethodManagerImpl.<init>(InputMethodManager.kt:57)

[Alex Vanyo]

I don’t believe there is a Compose 1.5.0-beta02 yet? That is indeed a new class first introduced in androidx.core 1.11.0-alpha04 , but on the latest Compose versions that should be brought in automatically

[kenkyee]

oops..typo. Meant to write beta01. Good to know it's in core 1.11. Thanks 🙂

[Alex Vanyo]

Are you seeing that error when updating to 1.5.0-beta01?

[kenkyee]

yes...manually switching android-core to 1.11.0-beta01 fixed it. But we're also not using the compose-bom yet.

[Alex Vanyo]

That shouldn’t be necessary, and compose-bom shouldn’t matter in this case. Will investigate this more, thanks for bringing that up!

[Alex Vanyo]

Is your project Android only or do you have a multiplatform setup?

[kenkyee]

Android only

[Alex Vanyo]

Which Gradle version are you using?
Also, if you have a minimal repro project with that issue that’d be helpful as well

[kenkyee]

Gradle 8.0.2.
I was just bumping versions in our project...I can see if I can come up w/ a small repro
