How do I pass a filename parameter to MediaPlayer in android kotlin?

How do I pass a filename parameter to MediaPlayer in android kotlin?

I have a sound file called "hello.wav" which is in the res/raw directory. I have tried the following code and it will not accept the parameter sndfil as there is no file called sndfil.wav in the res/raw directory...

    private var sndfil = "xxxxxxxxxx"

    fun playnow (sndfil: String) {
        mp = MediaPlayer.create(this, R.raw.sndfil)
        mp.start()
        return
    }

    playnow("hello")

How can a filename be passed as a parameter to android MediaPlayer ?

take a look at the getIdentifier method it returns a resource identifier for the given resource name.

fun playnow (sndfil: String) {
    val resourceIdentifier = resources.getIdentifier(sndfil, "raw", packageName)
    mp = MediaPlayer.create(this,resourceIdentifier)
    mp.start()
    return
}

playnow("hello")
