an exception is occurred while play an audio in blackberry

try {
    Player p = javax.microedition.media.Manager.createPlayer("abc.mp3");
    p.realize();
    VolumeControl volume = (VolumeControl)p.getControl("VolumeControl");
    volume.setLevel(30);
    p.prefetch();
    p.start();
} catch(MediaException me) {
    Dialog.alert(me.toString());
} catch(IOException ioe) {
    Dialog.alert(ioe.toString());
}

I used above code to play an audio in blackberry. But it gives an exception error as mentioned in below.

javax.microedition.media.MediaException

If you look at the BlackBerry API docs, you see that for the version of createPlayer() that you use:

MediaException - Thrown if a Player cannot be created for the given locator.

It also says:

locator - A locator string in URI syntax that describes the media content.

Your locator ("abc.mp3") doesn't look like it's in URI syntax. You could try changing that, to something like "file:///SDCard/some-folder/abc.mp3".

Or, if the mp3 file is an app resource, I usually use this code:

    try {
        java.io.InputStream is = getClass().getResourceAsStream("/sounds/abc.mp3");
        javax.microedition.media.Player p =
            javax.microedition.media.Manager.createPlayer(is, "audio/mpeg");
        p.realize();
        // get volume control for player and set volume to max
        VolumeControl vc = (VolumeControl) p.getControl("VolumeControl");
        if (vc != null) {
            vc.setLevel(100);
        }
        // the player can start with the smallest latency
        p.prefetch();
        // non-blocking start
        p.start();
    } catch (javax.microedition.media.MediaException me) {
        // do something?
    } catch (java.io.IOException ioe) {
        // do something?
    } catch (java.lang.NullPointerException npe) {
        // this happened on Tours without mp3 bugfix
    }
