Hi all, I'm trying to import a library with Jetpac...

# compose

[Lauren Yew]

Hi all, I'm trying to import a library with Jetpack compose 1.0.0-beta01 (Android Gradle plugin 7.0.0-alpha09) into an app that doesn't have jetpack compose and android gradle plugin 4.1.0. I'm getting an error

java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/compose/runtime/internal/ComposableLambdaKt;

when I try to open up my compose views from the library.
Has anyone seen this kind of issue before / know a fix?
I thought compose could be used in a library only and then not be required for the app (my client app has product requirements limiting it from updating the AGP / going to compose).

How does your client code consume the library’s compose views?

From my experience, If you’re trying to directly call the Composable functions - that won’t work. So what you have to do is wrap the Composable in a custom Android view with ComposeView/AbstractComposeView, and expose that from the library (without any reference to compose)

My client code opens up an activity from the library that consumes compose views.

When you say 'library', is this a library module in the same project? Or an AAR distributed over Maven/etc

[cb]

Sounds like the Gradle app module isn't picking up the Compose transisitive dependencies, but that's a total guess

[Lauren Yew]

It's a library AAR distributed over mavenLocal

@cb any updates on this?

[Lauren Yew]

I've tried using implementation and api with the build.gradle. Both result in the same error.

I don't really have an update for you tbh. Difficult to know what the issue is without looking at the code.

Does .gradlew androidDependencies list any Compose dependencies?

[Lauren Yew]

It does not. Looks like it brought in my library dependency but not any compose dependencies
