Comment 0 for bug 1230391

After bug #1224756 is fixed, we should provide a visual cue for when an app moves to the background and is recording audio. This will allow an app like Skype to work normally in the foreground, but if the user launches another app into the foreground, the user is able to see that he/she is still on the Skype call. In addition to the usability benefit, this provides a security benefit because it stops eavesdropping because the user will have a visual cue that the malicious/misbehaving app is recording audio.
