MediaPlayer doesn't work
<p>I created a simple application.
In my main activity class i use this to play a sound when a button is clicked</p>

<pre><code>MediaPlayer buttonSound = MediaPlayer.create(this, R.drawable.button_sound); 

public void onClick(View arg0){
                buttonSound.start();
                             }
</code></pre>

<p>In my main activity class i have a service that start a background music</p>

<pre><code> Intent svc=new Intent(this, BackgroundSoundService.class);
 startService(svc);
</code></pre>

<p>the problem is that if i dont' start the service <code>startService(svc);</code> the button sound don't play!
Why? They are two differents things!</p>
