Controlling overall system volume from app?
<p>I'm building an application in which I would like to let the user control the volume via the app (instead of pressing down the side volume buttons). </p>

<p>Is there a way to control the "overall" system volume from within the app? If not, I would be content controlling media player volume and phone (ringer + in-call) volume. I create my own local MediaPlayer object, so I think that shouldn't be so hard to control. </p>
