title: Get instance of Android system service(for example, AudioService)
body: <p>I know that AudioManager provides API for AudioService. However, that I want is to get instance of AudioService class.</p>
  
  <p>Studying the source showed that AudioManager makes a call to class in remote service.</p>
  
  <p>I know that AudioManager have a field "sService", but is not an instance of AudioService, instead it is an instance of BinderInternal, IIRC. Can I somehow gain access to instance of AudioService? Or it is totally impossible because of security issues?</p>
