the hands-on tutorial use

jvm("android")

for targeting android but I’m reading in the doc that one could also use

android { ... }

. Is the

android

shortcut useful only to be able to configure build variants, dependencies, etc… ? The doc says also

id("com.android.library")

is necessary but gradle can’t resolve it

Plugin [id: 'com.android.library'] was not found in any of the following sources:

(and then nothing, it does not say any sources). What if I want to target android and desktop through the jvm? should I just use

jvm()

?

Have you add android gradle plugin to build script dependencies?

I’ve added this

buildscript {
    repositories {
        mavenCentral()
        google()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:4.1.0-beta03")
    }
}

which makes

apply(plugin = "com.android.library")

works but still not for

id("com.android.library")

in the

plugins

bracket

Is the snippet you've shown in the root project's

build.gradle[.kts]

file?

yep

I don't think it is possible, you most likely need to have a subproject for the android library.

ok so that would mean the mpp project only use the

jvm()

target and my android project using the shared code should declare a

kotlin {
    android { ... }
}

?

FYI, if you want to share code between Android and JVM, it's currently best to make a plain Kotlin/JVM library module, and ensure the java APIs you use are available on Android (avoid desktop specific APIs). Then, in the desktop or android specific library/app module, you can use the platform specific APIs, and implement some interfaces if needed using these platform APIs.

I’ll keep that in mind, thanks!

Haha, you figured it doesn't explain the

jvm("android")

thing 😄

yeah no, I guess they could actually use it since their shared code module is inside the android project 🤷‍♂️

I think it was easier to test jvm support and fix any issues than android support which they don't control directly, and is more complicated on several levels. I'm hopeful this will improve, especially with 1.4 and 1.4.20

use an android target if you need to do any Android things, like use the Android SDK or configure flavors
