Can't play .opus files with MediaPlayer in Kotlin

Question

I was trying to create a simply MediaPlayer but when playing .opus files it is not working. I tested it with an mp3 and it worked (but does not renaming the opus to mp3, for example). I've read something about .mkv (Matroska Container Format) but I don't know what exactly is it and if it could help me.

In my code I've something like this:

var player : MediaPlayer = MediaPlayer()
var uri : Uri = Uri.parse(selectedFile.absolutePath)

    try {
        player.setDataSource(selectedFile.absolutePath)
        player = MediaPlayer.create(this, uri)
        player.prepare()
        player.start()
    }catch (e : Exception){
        Toast.makeText(this, "Error reading file", Toast.LENGTH_SHORT).show()
    }

And I got different errors trying to solve it, but this is the one I have now (exactly in the MediaPlayer.create line):

Renaming to any other format such as is suggested there was useless for me — Pablo Gutiérrez, Mar 07 '19 at 01:37

According to the doc the MediaPlayer class does not support .opus files

https://developer.android.com/guide/topics/media/media-formats

The indication in there saids that can play dot mkv files using the opus codec. Dot mkv files are another types of files, another extension.

Further more, mkv files are only supported on the 5 or later OS.
