Hey guys, I'm working on a ringtone picker as part of my app, part of that is listing all audio files on the user device and playing them individually upon user request, thread 🧵

So I use the MediaStore API to list all the audio files as follows:

val projection = arrayOf(
    MediaStore.Audio.Media.DISPLAY_NAME,
    MediaStore.Audio.Media.DATA
)
val selection = MediaStore.Audio.Media.IS_MUSIC + " != 0"
appCtx.contentResolver.query(
    MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
    projection,
    selection,
    null,
    null
)?.asSequence()?.map {
    Ringtone(
        name = it.getString(0),
        source = MediaSource.Path(it.getString(1))
    )
}?.toList().orEmpty()

and to play the selected file, I use android.media.MediaPlayer and give it the file path as a data source:

player.setDataSource(appCtx, Uri.parse(source.path))

I'm requesting these permissions to do so:

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" android:maxSdkVersion="32" />
    <uses-permission android:name="android.permission.READ_MEDIA_AUDIO" android:minSdkVersion="33" />

I also request them at runtime, but on Android 10 devices (and probably on newer ones as well) I'm getting this error:

java.io.FileNotFoundException: /storage/emulated/0/Samsung/Music/Over_the_Horizon.mp3: open failed: EACCES (Permission denied)

I know this's related to scoped storage, but I can't figure out from the docs how to fix it

Wrong workspace. Over here we talk about the Kotlin programming language and all related topics. You question is pure android and should be asked on a different platform.
