title: How to get Verbose logging in logcat for a specific module
body: <p>One of the android Modules (AudioFlinger) has support for verbose logging (with Tag=AudioFlinger).
  Question is how can I see those logs in the logcat? </p>
  
  <p>I did the setprop log.tag.AudioFlinger VERBOSE - but it doesn't seem to work. Do I need to change something and then rebuild the android source again? </p>
