Alarms vs. TIME_TICK in Android
<p>I'm not sure which is these is appropriate for my current application.  </p>

<p>I need to switch wallpaper on a given, but user changeable, interval.  I've been using a BroadcastReceiver to check every minute, but then I saw <a href="http://stackoverflow.com/questions/1619133/hidden-features-of-android-development">this question</a>.</p>

<p>Is there any particular advantage to one method over another?  Right now I've got to keep a service alive to receive the broadcast, but would using alarms obviate that?</p>
