How to convert this file into an MP3 or is it already defined as MP3?

Question

here's my code but there's no sound being played

MainActivity.java

public class MainActivity extends AppCompatActivity {

private MediaPlayer mediaPlayer;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mediaPlayer = MediaPlayer.create(MainActivity.this,R.raw.file);

    Button playButton = (Button) findViewById(R.id.play_id);
    playButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
                mediaPlayer.start();
        }
    });

    Button pauseButton = (Button) findViewById(R.id.pause_id);
    playButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            mediaPlayer.stop();
        }
    });

}

my code works but there's no sound being played. i don't know what's wrong

also the format of the mp3 is weird it shows YT with black background which i don't understand.

Thanks for the try but it was my mistake in this line playButton.setOnClickListener(new View.OnClickListener() { it should be pauseButton, i only forgot to change it. Thanks
