I got the READ_MEDIA_AUDIO permission, and let user select an audio file. Audio file was played fine. But I want to load the same audio file at next startup, without making the user select the same file again (which is obviously inconvenient for the user). I saved the uri.toString() in the preference, and in onCreate, I read the string, and created the uri again.

    val sharedPreferences = getSharedPreferences("settings", Context.MODE_PRIVATE)
    val audioUriString = sharedPreferences.getString("last-audio", null)
    if (audioUriString!=null)
    {
        audioUri = Uri.parse(audioUriString)

        mp.setDataSource(this, audioUri!!)
        mp.prepareAsync()
    }

However, this did not work. It caused:

java.io.FileNotFoundException: null: open failed: ENOENT (No such file or directory)

What I am trying to do is not possible, and the user must select the same file in each session?
