Listen for ringer muted by volume button click
<p>i need to know in a background task if the user muted the ringer by clicking the volume button  when a call is coming in. so there are 2 possible events that i could listen for:</p>

<ul>
<li>volume button click (onKeyDown) - that would be the preferred method</li>
<li>ringer gets muted</li>
</ul>

<p>it seems though that this is not possible. anyone has an idea how to accomplish that?</p>

<p>Thx
Simon</p>
