Strangely, though, the following code does not work:

val recordAudioPerm = rememberPermissionState(android.Manifest.permission.RECORD_AUDIO)

Button(onClick={

if (! recordAudioPerm.hasPermission) {recordAudioPerm.launchPermissionRequest()}

}

){

Text("Record")

}

I mean, the permission prompt is never shown, and debugging shows that the value of recordAudioPerm is true!

Turns out I was running the code on an Android 5.0 device!

Runtime permissions work only with Android M+.
