How do I set up an audiofile to play when a user touches an image.

Where should I store the audio file and what code should I use to actually play the file? I don't want to bring up the MediaPlayer interface or anything like that.

I was thinking of doing it like this:

foo = (ImageView)this.findViewById(R.id.foo);
    foo.setOnClickListener(this);

public void onClick(View v) {
if (foo.isTouched()) {

 playAudioFile();
  }
}

Thanks
