The android.content.Context api exposes two methods for starting a service. startService and bindService. The api docs state that when a service is started with Context.startService, that requires the service to remain running until stopService(Intent) is called, regardless of whether any clients are connected to it.
I have made a test service that uses a postDelayed event. The Runnable for the postDelayed increments++ a counter and writes that counter and a timestamp to a text file every minute. However, when the phone becomes inactive (screen times out) the service seems to pause for a few hours, run a short while, then pause for a few hours, then run a short while, and on and on... Here is the log file. The service ran intermittently for 11 hours. I can post the Service.java and Activity.java if requested. I am leaving it out for berevity. 02/05/2009 10:27:07 PM: iCount = 1 02/05/2009 10:28:07 PM: iCount = 2 02/05/2009 10:29:07 PM: iCount = 3 02/05/2009 11:20:49 PM: iCount = 4 02/05/2009 11:31:11 PM: iCount = 5 02/05/2009 11:32:11 PM: iCount = 6 02/05/2009 11:33:16 PM: iCount = 7 02/05/2009 11:34:16 PM: iCount = 8 02/05/2009 11:35:16 PM: iCount = 9 02/05/2009 11:36:16 PM: iCount = 10 02/05/2009 11:37:16 PM: iCount = 11 02/05/2009 11:38:16 PM: iCount = 12 02/05/2009 11:39:16 PM: iCount = 13 02/05/2009 11:40:16 PM: iCount = 14 02/05/2009 11:41:16 PM: iCount = 15 02/05/2009 11:42:16 PM: iCount = 16 02/05/2009 11:43:17 PM: iCount = 17 02/05/2009 11:44:17 PM: iCount = 18 02/05/2009 11:45:17 PM: iCount = 19 02/05/2009 11:46:17 PM: iCount = 20 02/05/2009 11:47:17 PM: iCount = 21 02/05/2009 11:48:17 PM: iCount = 22 02/05/2009 11:55:58 PM: iCount = 23 02/06/2009 01:06:56 AM: iCount = 24 02/06/2009 03:07:41 AM: iCount = 25 02/06/2009 04:38:32 AM: iCount = 26 02/06/2009 06:54:49 AM: iCount = 27 02/06/2009 08:03:14 AM: iCount = 28 02/06/2009 08:57:50 AM: iCount = 29 02/06/2009 08:58:50 AM: iCount = 30 02/06/2009 08:59:50 AM: iCount = 31 02/06/2009 09:05:24 AM: iCount = 32 02/06/2009 09:06:24 AM: iCount = 33 02/06/2009 09:07:24 AM: iCount = 34 02/06/2009 09:08:24 AM: iCount = 35 02/06/2009 09:23:09 AM: iCount = 36 02/06/2009 09:23:17 AM: Service Destroyed. My questions are: 1) Is this what is supposed to happen for an Android service? 2) If so, What should one do to get an application to run a specific task at user-specified intervals in the background. Like retrieving data from a web service... --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
