title: Paho MQTT Android service wake up activity
body: <p>I am trying to use Paho Android MQTT library (<a href="https://eclipse.org/paho/clients/android" rel="nofollow noreferrer">downloaded from here</a>).
  The sample <em>service application</em> works fine, the <em>subscribe</em> and the <em>publish</em> methods work fine too when the sample application is running. When I <em>close</em> it, the device doesn't receive message notifications anymore.</p>
  
  <p>Does anyone has an experience how to modify/implement the service correctly to receive message even if the application isn't running?</p>
