Android does not put applications to sleep. In your case, Android is probably terminating your service for being everlasting and using a perpetual WakeLock. > This effectively renders the app ineffective for the task at hand. > I've read posts about using an Alarm to simulate a pseudo cron job but > I don't really need to be woken up in order to do a task, the app > needs to run code based on the location manager calling > onLocationChanged the service that the users position has changed. You can experiment with my LocationPoller, which is designed for your scenario: https://github.com/commonsguy/cwac-locpoll > yet the fact that it > effectively stops running in some cases is causing problems for the > users. That is because you cannot write everlasting services. Please use AlarmManager and something (LocationPoller or your own design) to write so you do not have a service and WakeLock in memory all of the time. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android Training in London: http://bit.ly/smand1 and http://bit.ly/smand2 -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
