android Mediaplayer can not work in emulator

I'm begginer in android Programming My Question is...

I wanted to play backgroud Music. So I read a code like this

public class Welcome extends Activity {
    /** Called when the activity is first created. */

    MediaPlayer player;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);        

        player=MediaPlayer.create(Welcome.this, R.raw.song);
        player.start();

But this code doesn't work in emulator. Error occured...

My Logcat is here..

You need to use one of the supported file formats. WMA is not one of them.
