Android: Get Notified when the current Mode inside AudioManager gets changed : <p>In Android I need to get notified when the current <strong>audio mode</strong> gets changed.</p>

<p>I can get this value through <a href="http://developer.android.com/reference/android/media/AudioManager.html#getMode()" rel="noreferrer">getMode()</a> but this is polling.  </p>

<p>I don't want to poll every few seconds.  </p>

<p>What are my options?  </p>

<p>(Please note that I'm not asking about ringerMode)</p>
