You have to use service because its always runs in background . Thread and AsyncTask and any other handlers not give guarantees to runs in background life time of applicatin.

Here you can find good tutorial for service.

Best to use a service, actually the best option there is to it. Always consider the users of your application as they do not want to see all that incoming and outgoing flow of data.
