title: GPS Tracking App (strategy)
body: <p>I am currently working on a GPS tracking App (only the distance, not storing each value or displaying in a MapView) for a car-drivers logbook.
  Cause of a docked phone, I do not care about power consumption.
  My implementation so far is an activity that calls a GPS-Helper class which is getting the long/lat.
  The activity itself calculates the driven distance, displays it for the user and starts a notification bar that also displays the distance. To keep the activity active and not killed by the OS, I am using a PARTIAL WakeLock for the activity.</p>
  
  <p>My problem is that this is not working correctly, cause my App seems to be killed by the OS inspite of the WakeLock. I think that it is killed, cause when I click on the notification bar item (after 15-30 min. for example) to see the driven distance in my running activity, the activity is shown as it is to start a new GPS-track instead of displaying the driven distance from the former started track.
  The WAKELOCK Permission is correctly set in the Manifest.</p>
  
  <p>My question now is to get know if this costruct could be working or is there a better way to do this?</p>
