# multiplatform

[Daniele Segato]

This documentation page https://kotlinlang.org/docs/multiplatform-android-dependencies.html on kotlin multiplatform android depencencies states:
> to move a debugImplementation dependency from the top level of an Android project, you’ll need to add an implementation dependency to the source set named androidDebug. To minimize the effort you have to put in to deal with migration problems like this, you can add a dependencies {} block inside the androidTarget {} block:
however when I try to use androidTarget {} in either the build.gradle.kts sourceSets block or inside a build-convention plugin I get this error:

The target 'android' already exists, but it was not created with the 'android' preset. To configure it, access it by name in `kotlin.targets`.

I’ve already tried applying the com.android.kotlin.multiplatform.library before the org.jetbrains.kotlin.multiplatform plugin without any change in the error message

And if I try using

getByName("androidDebug") { }

I get

KotlinSourceSet with name 'androidDebug' not found.

So, apparently this issue I had was caused by me using com.android.kotlin.multiplatform.library plugin over com.android.library .

they are both plugins released by Google with AGP, the first is newer and is supposedly going to eventually replace com.android.library for multiplatform libraries using Android (but I actually hope they’ll take another route, cause multiplatform and android library shouldn’t be put together IMHO).

The 2 plugin conflict with each other, if you use com.android.library you cannot also use com.android.kotlin.multiplatform.library .
If you use the regular com.android.library than it does what is needed to init the android component and therefore you can than use androidTarget { } inside the kotlin { } section of configuration for the org.jetbrains.kotlin.multiplatform plugin.

AND if you use com.android.library android studio will support compose previews in androidMain while if you use com.android.kotlin.multiplatform.library the preview will not be available.

Conclusion of all this: do not use com.android.kotlin.multiplatform.library , at least not yet.

I’ll add I found no way to target debutImplementation with dependencies using com.android.kotlin.multiplatform.library (which might not mean there isn’t one, I just couldn’t find one)

Hi, Daniele! I move out from this plugin too. how did you setup the android tests with the old plugin?
