title: Can phonegap app work in background?
body: <p>what I mean is working in totally background, e.g. even the screen is shut down, the app is running and can send notifications with a sound.</p>
  
  <p>My app is used for watching price changes. There will be an alert with a sound when a price changes.</p>
  
  <p>So, the answer should be yes or no? Thanks.</p>
