APK doesn't include *.version files in metadata

[pswaminathan]

Android Studio's Layout Inspector has specific support for Jetpack Compose components, including recompositions. However, this requires certain files to be present in the final APK:

Note: If you're not seeing Compose components in layout inspector, make sure you are not removing META-INF/androidx.compose.*.version files from the APK. These are required for layout inspector to work.

These show up in the deploy jar, but get filtered out of the APK. When building rules_kotlin's Compose example:

I've raised this issue with the Android Studio team here: https://issuetracker.google.com/issues/410000462

[pswaminathan]

@ted-xie there is a PR open #356 that resolves this, if you're able to have a look.

[ted-xie]

Yes, I saw that. Our internal version of ASwB seems to work out of the box with no additional changes to the resource extractor, so I'm reaching out first to the Studio team to determine why/how it works on our side as-is.
