In a classic KMP project, is there any easy way to have separate debug resources for the Android target?
Specifically without duplicating the androidMain variant since it already contains the Android-specific code. (I guess you would need to add yet another shared module for android, but I wonder if someone has done it somewhere)

My usecase is just to have a separate debug variant app icon and app name string.

I'd like to know if there's way too. I always have a separate icon for debug builds and this would be super useful (but also in general, would like to know how Android build flavors and variants play with KMP)

[Skaldebane]

One idea is to just use KMP modules and make them depend on androidMain (e.g. androidRelease and androidDebug ), but I'm not sure if and how would that work with resources, and I'm not very fond of the extra directories either.

[Rok Oblak]

Yeah, that was my thinking also, but it seems overkill for just having an override for an icon and a string...

[Joel Denke]

If its just for icon, I created my own Kotlin dsl inject resources by environment. So not even need to be part of build type. Did it to avoid flavors.
You can merge external resource folders with the one used by Android app. I also using same method to inject google play services json.

For now, I just used manifest placeholders for the app name which works fine enough.

[Skaldebane]

@Joel Denke that's interesting, can you share more details about that?

[Skaldebane]

@Rok Oblak would you mind sharing how that works? I'm not sure I understand what "placeholders" mean here

[Rok Oblak]

I set a manifest placeholder for appName .
Then I set this custom string in my build.gradle.kts in the
android { defaultConfig {

manifestPlaceholders["appName"] = "DEBUG_NAME"

and then in buildTypes { release ...

I can override it just for android release build type:

manifestPlaceholders["appName"] = "RELEASE_NAME"

[Rok Oblak]

And you can do the same for app icon, though I haven't done it yet

[Skaldebane]

Didn't know about manifestPlaceholders, that's very neat, thanks for sharing!

This is how. Regular srcSet settings :)

Also its possible create a custom Gradle task that just download and/or copy files from disk to certain place coupled into Android compile loop. I use that for copy google play services json.
