title: GPS not updating when phone is in sleep mode
body: <p>My Application needs to pick up location information at regular intervals. I use <code>AlarmManager</code> to do it and it works fine. The problem is that when the phone goes to the standby/sleep mode the GPS location listener gets removed. 
  After some time when my <code>AlarmReceiver</code> gets fired it looks for the latest location update which it does not get because GPS has been turned off due to the standby mode.</p>
  
  <p>Is there a way how I can wake up the location listener when my <code>AlarmReceiver</code> gets fired or any other alternative?</p>
