title: Starting an Android init.rc service from an Activity
body: <p>Before I start, this is meant for our own android based device and not for a phone nor for deployment elsewhere.</p>
  
  <p>We have a service in init.rc that is a postgresql database server. This launches on startup and always runs in the background for the system. There's the possibility that it might close however and we would like to have a way to stop and start this service from the android side of the system. </p>
  
  <p>Is there a way to send an init start command from an android Activity? From a root shell, this would be the equivalent of running "start servicename" and "stop servicename".</p>
