How to add play/pause/stop to audio

Peter thank you for the reply but i tried the code below but still the button controls are not working

HTML
<div class="clear">
<button >Play Some Audio</button>
<br>
<button >Play Some Audio</button>
<br>
<button >Play Some Audio</button>

</div>

AudioInterface
//Pause an audio file from the webpage
@JavascriptInterface
public void pauseAudio(String aud) { //String aud - file name passed
//from the JavaScript function
final MediaPlayer mp;

try {
AssetFileDescriptor fileDescriptor =
mContext.getAssets().openFd(aud);
mp = new MediaPlayer();
mp.setDataSource(fileDescriptor.getFileDescriptor(),
fileDescriptor.getStartOffset(),
fileDescriptor.getLength());
fileDescriptor.close();
mp.prepare();
mp.pause();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Can you give an idea of how to implement this properly
