MMAPI (JSR 135) allows Java ME applications to easily access MultiMedia functionalities, like playing and recording both video and audio data. This article shows the steps required to play a sound, from both local and network resources.

Source code

You need to import the following packages:

import java.io.*;
import javax.microedition.media.*;

The following code helps to play sound which is embedded in your jar file

InputStream is = getClass().getResourceAsStream("sound.wav");
Player p = Manager.createPlayer(is, "audio/X-wav"); 
p.start();

The following code helps to play sound which is stored in a web server

Player p = Manager.createPlayer("http://server/sound.wav"); 
p.start();

You may also try other sound formats by minor changing ie; by changing the mime type.

Also you have to keep in mind while giving the url in the second case, use of special characters like '&' etc are not supported. In such case you should follow the following method

HttpConnection hc = (HttpConnection) Connector.open(url);
InputStream in = hc.openInputStream();
Player p = Manager.createPlayer(is, "audio/X-wav"); 
p.start();

Notes

• When playing a multimedia file, you should always check if the used format is supported by the target device. To do this, you should use the Manager getSupportedContentTypes()
• Also, you should always check which protocols are supported, by using Manager getSupportedProtocols() method
