title: Is a live internet connection required for push notification?
body: <p>This maybe a silly question, but I need confirmation and I have no one else to ask.</p>
  
  <p>I am trying to understand the implications of implementing my own push notification for android mobile devices. This requires a continuous TCP connection to a server, though most of the time it will be idle. </p>
  
  <p>My assumption is that, even when idle, for the server to be able to push data to the client through the TCP connection, an active internet connection will always be required, and if the connection is disrupted (i.e. the user switches the connection off) this push will no longer be possible.</p>
  
  <p>Is this assumption correct ?</p>
