title: Android: Proximity Alert
body: <p>I have followed <a href="http://www.javacodegeeks.com/2011/01/android-proximity-alerts-tutorial.html" rel="nofollow">this tutorial</a> about how to use the proximity alert and how to register it.
  It all works but when I close the app (with the back button, not the home-button) then the proximity alert does not work anymore. Does anyone know how to set it so that it runs in the background?
  Thanks in advance!</p>
