Support for playing Kotlin Multiplatform resources

[Woren]

Use case description

Main use case is about playing files inside APK with not only for example Uri: Uri.parse(("file:///android_asset/music.mp3"))

But to be able to use files located in jar archive. For example Uri: jar:file:/data/app/~~4hhLse7uFXE7V7sA==/com.example.composetest-jD6eQ3BeyvfQ==/base.apk!/composeResources/com.example.shared.resources/files/music.mp3

This approache can be used for multiplatform applications (e.i. multiplatform media players using AVPlayer on iOS and Exoplayer on Android with shared code) using Compose Multiplatform which will generated resources Uri for files inside common/shared directory. Mentioned directory "android_asset" is not accessible on iOS and generated resources Uri can't be used on Android. Media files needs to be duplicated to proper platform dependend directories.

Proposed solution

Be able to use following code: val mediaItem = MediaItem.Builder().setUri(Res.getUri("files/music.mp3")).build()

Alternatives considered

Only solution I can think of is using custom MediaSource and handling InputStream using method from Compose Multiplatform: Res.readBytes("files/music.mp3") with solution mentioned for example here (Exoplayer issue) Similar issue is opened in Compose Multiplatform repository here and support from this side is not coming. The reasons are mentioned there.

Thank you for consideration!
