# multiplatform

[Colton Idle]

I have a semi-recent android project that I'm trying to convert to multiplatform (both kotlin and compsoe multiplatform)

Step one is that I added

alias(libs.plugins.composeMultiplatform)
alias(libs.plugins.androidApplication)
alias(libs.plugins.kotlinMultiplatform)
alias(libs.plugins.kotlinMultiplatformPlugin.compose)

but now when I run my app it tells me my manifest is in the wrong place. it wants it in /androidMain

Is there a way to do that easy wai to tell it not to look in androidMain., but just main?

[eygraber]

Something like:

android {
  sourceSets.named("main") {
      manifest.srcFile("src/main/AndroidManifest.xml")
  }
}

Cool. Do you know if I should maybe just set my android :app module without kotlinMultiplatform even though I plan on creating a new module called :appMulti and slowly migrate pieces of the app to it?

[Colton Idle]

Only reason why i ask that is because i have different build variants for my android build like free and paid and they have their own manifests... and i feel like this might just cause an issue

[eygraber]

I've been going back and forth on that in my projects. I think I've been making my Android app modules non multiplatform (i.e. I use the kotlin android plug-in)

[Colton Idle]

okay. lemme try that.

kotlin android is still available at 2.0.0 right?

[eygraber]

Yup

[eygraber]

I think it's going to be a while before it's deprecated (if ever)

[Colton Idle]

and then i would not be able to use jetbrains compose right?

[Colton Idle]

let me give this a whirl. because i tried yest and failed

[Colton Idle]

alias(libs.plugins.composeMultiplatform)
alias(libs.plugins.androidApplication)
alias(libs.plugins.kotlinAndroid)
alias(libs.plugins.kotlinMultiplatformPlugin.compose)

[Colton Idle]

Yeah. error

error resolving plugin [id: 'org.jetbrains.kotlin.android', version: '2.0.0']

The request for this plugin could not be satisfied because the plugin is already on the classpath with an unknown version, so compatibility cannot be checked.

[eygraber]

You could still use Jetbrains compose plugin. Just make sure you're not enabling jetpack compose also (with `buildFeatures`; I think that's "deprecated" now anyways because of the Kotlin compose compiler).

That error is a leftover issue with plugins from version catalogs that will hopefully be fixed by gradle soon.

Try replacing the alias call with kotlin("android") and see if that works.

added kotlinAndroid to my root build.gradle and everything worked!

[Colton Idle]

woot.

[Colton Idle]

thanks for the tip

[Colton Idle]

so now i have

alias(libs.plugins.composeMultiplatform)
alias(libs.plugins.androidApplication)
alias(libs.plugins.kotlinAndroid)
alias(libs.plugins.kotlinCompilerPlugin.compose)

[Colton Idle]

Interesting enough. I do have

buildFeatures {
  compose = true

in my app (thanks for the reminder). I wonder why everything still seemingly worked lol

[eygraber]

The fix for the plugin should be in Gradle 8.8!

nice. just saw rc2 announced.

also stumbled upon this blog. pretty recent. good overview: https://touchlab.co/compose-multiplatform-transition-guide
