Question

I have a function save() which will send some data to server periodically after 15 minute. How can I achieve this function in service class. I have heard about alarm manager & handlers but does not know any implementation of those.

Answer 1

A high level overview. You need:

• A Service which can send the data to your server on demand.
• An alarm to periodically kick off your Service.

Take a look at IntentService as it will simplify some things for you. Assuming your implementation for save() is fairly isolated, you can pretty much just call it in onHandleIntent. Additionally, here is the documentation for AlarmManager, which you will need to set a repeating alarm. You give an alarm an Intent to fire. In this case, the Intent should point to your IntentService.
