How to catch that volume was changed?
<p>I use <code>SeekBar</code> for setting volume. I do the following:</p>

<ol>
<li>I get current volume by <code>getStreamVolume()</code> and pass it to <code>SeekBar</code> element by <code>setProgress()</code>.</li>
<li>I listen messages from the <code>SeekBar</code> element by <code>onStopTrackingTouch()</code> and set volume by <code>setStreamVolume()</code>.
It works. </li>
</ol>

<p>But user can change volume by hardware volume controls. I'd like to catch it and change <code>SeekBar</code> pointer position appropriately. How can I do it? </p>
