Service, handler, timer, runnable - which to use and how?
<p>I'm trying to make an Android app which contacts a webserver every 15 minutes to retrieve som kind of RSS. I know how to retrieve the RSS, but my problem is how I make the app contact the webserver periodically.</p>

<p>I've read about services, handlers, timers and runnables but I don't know which of them I should use, and how I should use them.</p>

<p>Thanks in advance.</p>
