Question

Well, in android, what is the difference between doing something in broadcastReceiver and calling another service in broadcastReceiver? I think they both run in background,right?

Actually, what I what to do is:

In certain time of everyday, download the user event(eg: 9:00 am eat
breakfast) from database, and set up the AlarmManager to show
notification about the event.

Now I set up a alarm manager to do the above task. And I am puzzled should I directly accomplish this in BroadcastReceiver or call service in BroadcastReceiver to accomplish this.

Thank You.

You should do as LITTLE processing in a BroadcastReceiver as possible because (quoting from the Android Blog)

When handling a broadcast, the application is given a fixed set of
time (currently 10 seconds) in which to do its work. If it doesn’t
complete in that time, the application is considered to be
misbehaving, and its process immediately tossed into the background
state to be killed for memory if needed.
