The simplest MMAPI MIDlet that can be built allows you to easily play a multimedia file from within your MIDlet without worrying about controls, feature sets, or security architecture. If all you’re doing is adding some sampled audio (or any other media) in a game, MMAPI allows you to do so in two lines of code. Listing below shows this code within a complete MIDlet.

//A Simple MMAPI MIDlet

import javax.microedition.midlet.MIDlet;
import javax.microedition.media.Manager;
import javax.microedition.media.Player;
public class SimplePlayer extends MIDlet {

public void startApp() {

try {

Player player = Manager.createPlayer(getClass().getResourceAsStream("/media/audio/chapter3/baby.wav"),"audio/x-wav");
player.start();

} catch(Exception e) {
e.printStackTrace();
}

}

public void pauseApp() {

}

public void destroyApp(boolean unconditional) {

}

}

To keep things simple at this stage, the media file is played by creating an InputStream on a wav file, which is embedded in the MIDlet’s JAR. This media file is kept in the folder media/audio/chapter3 and is called baby.wav (which is the sound of a baby crying).

Of course, you don’t need to play an audio file only. You can substitute the wav file with a video file, provided the emulator supports the format of the video file. The video will not show anywhere, because this listing doesn’t provide a mechanism to show the video. You can substitute the wav file for a midi, tone, or any other supported audio format. The point is that playing multimedia files using the MMAPI is as simple as creating a Player instance using the Manager class and calling method start() on it.

1.	when iam trying to executing above program i am getting warning like this java.lang.IllegalArgumentException at javax.microedition.media.Manager.createPlayer(+11) at SimplePlayer.startApp(+14) at javax.microedition.midlet.MIDletProxy.startApp(+7) at com.sun.midp.midlet.Scheduler.schedule(+270) at com.sun.midp.main.Main.runLocalClass(+28) at com.sun.midp.main.Main.main(+80) what should i do?i am very new to j2me.please help me.

2.	pls send simple to hard j2me coding By: Seenu at 2008-10-29 15:19:03
3.	java.lang.IllegalArgumentException means usually that the argument was illegal/wrong/broken XD. So... my guess is that your file path is wrong (the one you use to create the player) By: Seink at 2008-11-12 11:03:00
4.	me too got the same problem.... but m sure the file path is correct... By: HEHE at 2008-11-19 01:49:04
5.	I am not found a J2ME file for playing a audio player for my project. please help me for my project. By: S.M. ASHIQUER RAHMAN at 2008-11-22 22:33:43
6.	I want to say, that you have to give complete code of programs so that we learn something from your programs, I am satisfied with your sitee. By: Jasvir Yadav at 2009-09-05 07:23:15
7.	very good helped me a lot By: Swaran at 2009-12-30 09:51:36
8.	I agree with BHAGYALAXMI. I faced the same problem. Plz give us a complete project (small) on j2me. We are very novice. But thank u Vikram Goyal for his article. By: Alok at 2010-01-10 12:03:37
