Originally shared in #multiplatform.

Seeing this compiler BackendException on AS when building a multi module KMM project which uses Jetpack compose

org.jetbrains.kotlin.backend.common.BackendException: Backend Internal error: Exception during IR lowering

and this as render problems when preview tries to load in between

java.lang.NoSuchMethodError: 'void androidx.compose.material.TextKt.Text...'

Found a few other people who had the same issue here, on the issuetracker and even on SOF but none of the solutions that worked for them, worked for me unfortunately.

More details in the 🧵 .

Using -

Android Studio Bumblebee | 2021.1.1 Beta 1
gradle plugin - 7.1.0-beta01 | wrapper - 7.2
kotlin - 1.5.31
compose - 1.1.0-alpha06

Project structure-

Proj
----buildSrc
----kmmApp
----------androidApp // includes compose
----------iosApp
----------shared
-------------androidMain
-------------iosMain
-------------commonMain
----kmmLib1
----------androidMain // includes compose
----------iosMain
----------commonMain
----kmmLib2
----------androidMain
----------iosMain
----------commonMain
----settings.gradle.kts // include(":kmmApp:shared", ":kmmApp:androidApp", "kmmLib1", "kmmLib2")

So far I’ve tried -
• Since I was using buildSrc, added the fix suggested here
• added this to all modules

buildFeatures.compose = true
composeOptions.kotlinCompilerExtensionVersion = "1.1.0-alpha06"

• Multiple rounds of clean, rebuild and Invalidate caches, even a system reboot to see if I’d get lucky.
• Add remove compose and build as @Marko Novakovic suggested.
• switched to stable compose 1.0.4

I was getting this error when I wanted to add Compose to existing Android app. I was stuck with this for 2-3 weeks

I was removing and re-adding Compose over and over again and it worked somehow even tho working project and project with error looked completely the same….

I just tried that and my Gradle build just doesn’t finish building once I add compose back just to the androidApp module. 🥲 . Cancelling the build also runs indefinitely. Force quitting AS and trying again. Update: Got Timeout waiting to lock file hash cache error after reopening AS, so deleted gradle caches and rebuilding again.

Finally it rebuilt after 45 mins but the issue still remain.

Tried run & Install on a device but crashes with this on open- NoSuchMethodError: No static method setContent

[Marko Novakovic]

exact problem I had. can’t help you here, I solved it by adding to compose to my app over and over and over and over

Also this is how the preview looks.

This is still not fixed. I have posted issue here hoping it reaches the right people.
