Make a new project with name AudioPlaybackDemoScreen and copy the following code to AudioPlaybackDemoScreen.java
package audioplaying;

import java.io.*;
public class AudioPlaybackDemoScreen extends MainScreen implements
FieldChangeListener
{
Player p;
ButtonField audio;
private VerticalFieldManager vfm = new VerticalFieldManager();
public AudioPlaybackDemoScreen() {
audio = new ButtonField("Strat");
add(audio);
ButtonField playButton = new ButtonField("Play",
ButtonField.CONSUME_CLICK | ButtonField.NEVER_DIRTY);
playButton.setCommand(new Command(new CommandHandler() {
public void execute(ReadOnlyCommandMetadata metadata,
Object object) {
// Start the video
try {
p.start();
p.setLoopCount(-1);
} catch (Exception e) {
Dialog.inform(e.getMessage());
}
}
}));
add(playButton);
ButtonField pauseButton = new ButtonField("Pause",
ButtonField.CONSUME_CLICK | ButtonField.NEVER_DIRTY);
pauseButton.setCommand(new Command(new CommandHandler() {
public void execute(ReadOnlyCommandMetadata metadata,

// Pause the video
try {
if(p!=null){
p.stop();}else{Dialog.inform("Press start");}
} catch (Exception e) {

}
}
}));
add(pauseButton);
ButtonField closeButton = new ButtonField("Stop",

p.close();}else{Dialog.inform("Press start");}
} catch (Exception e) {
Dialog.inform(e.getMessage());
}
}
}));
add(closeButton);
audio.setChangeListener(this);
}
public void fieldChanged(Field field, int context) {
// TODO Auto-generated method stub
if (audio == field) {
try {

.createPlayer("http://www.virginmegastore.me/Library/Music/CD_001214/Tracks/Track1.mp3"
+ ";deviceside=true");
p.realize();
VolumeControl volume = (VolumeControl) p
.getControl("VolumeControl");
volume.setLevel(30);
p.setLoopCount(-1);
p.prefetch();
p.start();
} catch (MediaException me) {
Dialog.alert(me.toString());
} catch (IOException ioe) {
Dialog.alert(ioe.toString());
}
}
}
}
just run and use the buttons on the screens. :) enhance the code accordingly for yours need!!
