      PlayAudioMidlet midlet;
      private Display display;
      private Command play, stop, exit;
      private Player player;

      public AudioPlayer(PlayAudioMidlet midlet, Display display) {
            super("");
            this.midlet = midlet;
            this.display = Display.getDisplay(midlet);
            play = new Command("Play", Command.OK, 0);
            stop = new Command("Stop", Command.STOP, 0);
            exit = new Command("Exit", Command.EXIT, 0);
            addCommand(play);
            addCommand(stop);
            addCommand(exit);
            setCommandListener(this);
      }

      public void commandAction(Command c, Displayable d) {
            if (c == play) {
                  try {
                        playAudio();
                  } catch (Exception e) {
                  }
            } else if (c == stop) {
                  player.close();
            } else if (c == exit) {
                  if (player != null) {
                        player.close();
                  }
                  midlet.destroyApp(false);
            }
      }

      public void playerUpdate(Player player, String event, Object eventData) {
      }

      public void playAudio() {
            try {
                  player = Manager.createPlayer(getClass().getResourceAsStream("/helloworld.wav"), "audio/x-wav");
                  player.addPlayerListener(this);
                  player.setLoopCount(-1);
                  player.prefetch();
                  player.realize();
                  player.start();
            } catch (Exception e) {
            }
      }
}

and PlayAudioMidlet java file in AudioSample package

package AudioSample;

import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

public class PlayAudioMidlet extends MIDlet {
      private Display display;
      AudioPlayer ap;

      public void startApp() {
            display = Display.getDisplay(this);
            ap = new AudioPlayer(this, display);
            display.setCurrent(ap);
      }

      public void pauseApp() {
      }

      public void destroyApp(boolean unconditional) {
            notifyDestroyed();
      }
}

and i put helloworld.wav in the project folder,,but when i run,,,there is nothing happened

[grahamhughes]

      public void playAudio() {
            try {
                  player = Manager.createPlayer(getClass().getResourceAsStream("/helloworld.wav"), "audio/x-wav");
                  player.addPlayerListener(this);
                  player.setLoopCount(-1);
                  player.prefetch();
                  player.realize();
                  player.start();
            } catch (Exception e) {
            }
      }

Avoid empty "catch" blocks like this... the device could be throwing you an exception to tell you the problem, and you're just ignoring it.

            } catch (Exception e) {
                append(e.toString());
            }

See what appears.

Hi!!
First check where you are storing the songs ie .wav file. You should store it in the resource folder. Give a correct path in your code.If this does not work I can give you the code I implemented.
Following is a part of code see if u can use:

try
{ InputStream in =getClass().getResourceAsStream("/music.wav");
Player player=Manager.createPlayer(in,"audio/x-wav");
player.start();
}
catch(Exception e)
{

System.out.println("Error");
return;
}

The song music.wav is included in the resource folder.
I hope its of some help

Check the JAR file that is created by your program, rename it as zip, open it using WINZIP and see if "helloworld.wav" is available inside it and at what path ? Let us know your findings and cut&paste your codelet matching to -

try
{ InputStream in =getClass().getResourceAsStream("/music.wav");
Player player=Manager.createPlayer(in,"audio/x-wav");
player.start();
}
catch(Exception e)
{

System.out.println("Error");
return;
}

Hey fayed,
Welcome to Forum Nokia Discussion Boards..

Well I have seen your code and I found a couple of issues with the same..as follows:

1.Please remember that while you play any of the multimedia file, run in the thread.Never start a player inside the commandAction() of the keypressed().
2.Why have you design and define the two midlets?
That is not required...
You take the AudionPlayer class and inside the commandAction(), if the command is play you start the thread and inside the run() you start the player and see if this works for you...
Well you can follow like this;
