Android - Volume Buttons used in my application
<p>I need to use volume buttons to control a variable parameter in my application. 
I use <code>Activity.onKeyDown</code> to get notified when the button is pressed but the media volume is also increased.<br>
Android is doing something like below when I press the volume key:</p>

<ol>
<li>increase media / ringtone volume  </li>
<li>pass the event to my application</li>
</ol>

<p>Is there a way to avoid increasing the system volume and use volume key only for my application?</p>
