Hello everyone. Im trying out the new <Resources> system with compose version 1.6.11 on Kotlin 2.0.0...

Hello everyone. Im trying out the new Resources system with compose version 1.6.11 on Kotlin 2.0.0. I have added an audio file composeResources/files/sound.mp3 . According to the post we're supposed to use Res.getUri("files/sound.mp3") to get a file path to read. Im new to Compose and especially Multiplatform and Im not sure how to read the file. I couldn't find any File class in commonMain so I created an expect/actual fun playSound(path: String) which I tried on Android by first reading the file with:

// path = "jar:file:/data/app/~~BCW32IAnb6EGfMOQvBQalQ==/<BUNDLE_ID>-di96yWV7A2Xl2lR01kWHBw==/base.apk!/composeResources/<PROJECT_NAME>.generated.resources/files/alarm.mp3"

actual fun playSound(path: String) {
    File(path).readBytes() // Throws java.io.FileNotFoundException
}

Any help would be highly appreciated.

I just now tried with the kotlinx-io-core package with SystemFileSystem.exists(Path(path)) which returns false

Hi, @Philip Fryklund did you solve this? I'm trying to use Res.getUri to play a wav file, and I got filenotfoundexception when passing it to AudioSystem.getAudioInputStream:

val uri = Res.getUri("files/frog.wav")
val audioInputStream = AudioSystem.getAudioInputStream(File(uri))

We “solved” it using a expect/actual and used a MediaPlayer on Android and AVPlayer on iOS. So we have 2 copies of the audio file and access them natively on each platform. Not ideal but solved the problem we had then.

Hi, thanks, what do you mean with 2 copies? I just develop for compose desktop, have only a single platform, and the wav files are stored on commonMain/composeResources/files/frog.wav

[Pablo]

As I don't need various media player but just one, the java one I use in desktop, I don't think expect actual is necessary

[Pablo]

the issue is the filenotfoundexception

[Per Jaakonantti]

Our project was iOS and Android only. So not sure about how to do it on desktop.

This is how we get it on Android:

MediaPlayer.create(context, R.raw.alarm)

The file is not in commonMain though.

So I’m afraid I can’t help 😕

[Pablo]

then you solved it without using Res.getUri("") ?

[Per Jaakonantti]

Correct!

[Pablo]

ouch

[Pablo]

ok, thanks
