Question

I am confused on when I should use a PendingIntent vs. a LocationListener for getting locations. If I have a service that always stays alive, is it ok to use LocationListeners?

Answer 1

If the component needing location updates only needs updates when the component is around — say, an activity — I’d use the
LocationListener approach.

If the component needing location updates specifically will not be
around — say, an IntentService — I’d use the PendingIntent. You
can’t use the LocationListener in this case, since there is nothing in
memory to be listening for locations.
