How do I get the icon to resolve? - I've confirmed ic_launcher_foreground.xml exists.

Specifically it's found at composeApp/src/androidMain/res/drawable/ic_launcher_foreground.xml

[Seri]

You probably want to be using R.drawable, not Res.drawable. Make sure that the R file you're importing matches the module containing the resource.

[Samuel]

I don't have R in Kotlin Multiplatform; Res is what I have.

[Pablichjenkov]

There is 2 things mixed here. There is Android resources API and the CMP resources API. In commonMain you use Res.drawable.mypng . In androidMain I believe you can use both, R.drawable.my_only_android_png as traditionally, but you can also resolve Res.drawable.cmp_png although not advisable

[Pablichjenkov]

To use the code you posted you have to place the resources under commonMain/composeResources/drawable directory. The directory in your screenshot is only accessible from androidMain and you should use R instead of Res if that is what you want.

[Samuel]

Wait so how do I add an icon to my desktopMain?

I target Android, iOS, web and desktop.

composeApp/src/desktopMain/kotlin/dev/myname/main.kt what do I use here? - For icon = of Window?

[Samuel]

Oh I see, so it's in

composeApp/src/androidMain/res/drawable
composeApp/src/androidMain/res/drawable-v24

but it needs to be elsewhere. In Android Studio there are no res directories apart from the androidMain one; that aren't generated.

[Pablichjenkov]

I quite don’t get what you want. If you want an icon for your desktop App or Android App. Each platform has a specific API to set the App icon. That is separate from compose and you should follow the proper API per platform.
What I describe above was the API to access a drawable or any resource from composecode, lets say to display it on a screen. But is not related to the App icon.

[Samuel]

Yes I already have `iconFile.set(rootProject.file("assets/icon.icns"))`for macOS, iconFile.set(rootProject.file("assets/icon.ico")) for Windows, iconFile.set(rootProject.file("assets/icon.png")) for Linux. My question is about how to access resources from composeApp/src/desktopMain/kotlin/dev/myappname/main.kt ; what to put in icon= for my org.jetbrains.compose.ui/ui-desktop/1.8.0-dev1890/c830ee7608c7e0c5d80489c58f3bdc74fe50f079/ui-desktop-1.8.0-dev1890-sources.jar!/desktopMain/androidx/compose/ui/window/Window.desktop.kt.

I don't seem to be able to access assets that I've imported. Elsewhere in my multiplatform code I use Res.drawable and it works.

[Pablichjenkov]

Ok, perhaps is worth filing a bug. You will need a minimum reproducer public repo.

How do I get Res.drawable.logo to work? - I've been hacking around a bunch and now it looks like:

% fd -Iexml logo
composeApp/src/debug/res/drawable/logo.xml
composeApp/src/androidMain/res/drawable/logo.xml
composeApp/src/release/res/drawable/logo.xml
composeApp/src/main/res/drawable/logo.xml
composeApp/build/intermediates/packaged_res/debug/packageDebugResources/drawable/logo.xml
composeApp/build/intermediates/packaged_res/release/packageReleaseResources/drawable/logo.xml

But I still can't icon = painterResource(Res.drawable.logo)

[Pablichjenkov]

You have to place the logo.png or logo.xml icon under: commonMain/composeResources/drawable

[Samuel]

Even after a direct cp composeApp/src/debug/res/drawable/logo.xml composeApp/src/commonMain/composeResources/drawable it doesn't resolve. Trying a bunch of gradle tasks now to see if any force generation

[Samuel]

Oh weirdly specific errors about upgrading from Kotlin 2.0.20 to 2.0.21 and now it works. No errors, but also no non-default icon

[Samuel]

Can this icon not be changed [macOS]?

[Pablichjenkov]

Humm 🤔 I believe you can. WRT the other issues , like I said, if it persists worth opening an issue in GitHub or YuoTrack

[Samuel]

Got a duplication error so removed all logo.xml files except the one in composeApp/src/commonMain/composeResources/drawable . Android logos all work now. iOS icon is default [at least in Simulator]. Web has no favicon but that's probably a different setting.

[Pablichjenkov]

Yes the fav icon is platform specific

[Samuel]

Ok added issue https://youtrack.jetbrains.com/issue/CMP-7057

& thx for fixing my Android build
