Why don't you just start the service once and then add a timer or make the thread sleep for the amount of time you like? – CodeKrieger Jun 21 '11 at 23:30

This would require that the service process executes *always*. For hours. This is not resource effective. – Peter Lillevold Jun 22 '11 at 08:17

Thanks! I'm learning, i'll search how to add timer. Any suggest? – Ferran Jun 22 '11 at 08:40

Look into the AlarmManager.
Clarification: since you want the service method to run with hourly intervals, you do not want to keep your service process running all this time. By using the AlarmManager, the OS can kill the service when it is not needed, and then bring it up to execute the method when it is time.

What if the intervals are a matter of minutes ? Is it a good idea to use the AlarmManager ? Or better make the thread called by the service sleep for few minutes ? – Leeeeeeelo Feb 11 '13 at 08:04

1@Leeeeeeelo - for efficiency, with small intervals (less than 10-15 minutes), you should not go with AlarmManager. There are discussions on that elsewhere on SO, e.g. http://stackoverflow.com/questions/11434056/how-to-run-a-method-every-x-seconds – Peter Lillevold Feb 11 '13 at 08:31
