Cannot replay sound in J2ME

I have problem restart sound in J2ME. I want to create player in constructor, then call playExplosion() to play it, but it only plays once. I'm using Wireless Toolkit.

Sound class

public class Sound () {

    private Player playerExplosion;

    public Sound() throws IOException, MediaException {
        // Explosion
        InputStream is = getClass().getResourceAsStream("/explosion.mid");
        playerExplosion = Manager.createPlayer(is, "audio/midi");
        playerExplosion.realize();
        playerExplosion.setLoopCount(1);
    }

    public void playExplosion() {
        try {
            System.out.println(playerExplosion.getState());
            playerExplosion.start();
        } catch (MediaException ex) {
            ex.printStackTrace();
        }
    }
}

MyMIDlet class

public class MyMIDlet extends MIDlet() {

    public Sound sound;

    public MyMIDlet() {
        // Init sound object
        try {
            sound = new Sound(this);
        } catch (Exception ex) {
            ex.printStackTrace();
        }

        // Test
        System.out.println("Start");

        for (int i = 0; i < 5; i++) {
            sound.playExplosion();

            // My sound is less than 1 second.
            try {
                Thread.sleep(2000);
            } catch (InterruptedException ex) {
                ex.printStackTrace();
            }
        }

        System.out.println("End");
    }
}

Output

Start
200
300
300
300
300
End

For the 1st time, playerExplosion state before start() is 200 (REALIZED).

For the 2nd, 3rd, 4th, 5th times, playerExplosion state before start() is 300 (PREFETCH).

At the moment, I have to create playerExplosion again in playExplosion() method, but it's too slow in a real device.

Try after removing 

playerExplosion.setLoopCount(1);

Realizing a Player can be a resource and time consuming process havint to create playerExplosion would mean calling playerExplosion.realize(); again that is why the process takes so much time

When your player is in PREFETCHED State what you need to do is just call playerExplosion.start(); but its not paying again because there is a general limitation on the number of times its should pay

Remove

  playerExplosion.setLoopCount(1);

And you would be able to pay your file several times

Thanks
