Hi, I'm an absolute beginner going through the Compose Multiplatform demo app. I got it to build and run for all of the targets except for Android, where I get the attached error message "please select Android SDK".

Under File->Project Structure->SDKs I have Android API 36.0, extension level 17 installed. Is there somewhere else I'm supposed to set the Android SDK? Thanks!

[Jack Boswell]

Yeah you need to set ANDROID_HOME environment variable
Or install the Android plugin in your IDE
Or set sdk.dir to your Android SDK location in your local.properties

[Jack Boswell]

I'm not really sure why we can select Android SDKs in project structure, but it doesn't really change anything

[Jack Boyce]

Thanks @Jack Boswell. I have all three of those things set. echo $ANDROID_HOME returns /Users/jack/Library/Android/sdk, this same value is in local.properties, and the Android plugin is installed (I think the Kotlin Multiplatform plugin installed it as a dependency). Any other ideas?

[Jack Boswell]

Weird, are you able to build OK? I'll check a new project on my machine

[Jack Boyce]

It builds fine, and runs all the other configurations fine (jvm, js, wasmjs, iOS). The Android one doesn't run for some reason – it pops up the error dialog I posted above.

[Jack Boswell]

Well yes, but are you able to build the Android configuration from the command line, or just executing the Gradle task manually?

[Jack Boyce]

jack ComposeDemo % ./gradlew :composeApp:assembleDebug

looks okay I think?

[Jack Boswell]

Yep, now we know it's just an IDE problem and not an environment one 🤔

[Jack Boyce]

I tried the obvious thing of quitting/restarting. Is there a way to flush temp files/cache?

[Jack Boswell]

File -> Invalidate caches/restart

[Jack Boyce]

That worked!! Big thanks

[Jack Boswell]

Nice! I think that's the first time I've seen IDE caches break that in particular 😄

[Jack Boyce]

I may have done something in a nonstandard order, not sure. 🤷‍♂️ Anyway thanks again, CMP full speed ahead!
