Android passing objects between activities

Question

Say if I have a locationManager(LM) object in activity A, which is my main menu. All the sub-activities need to use LM. In a good design, should I pass LM object to sub-activities? How? Please suggest some good coding pattern. Thanks.

Answer 1

You could use an Application object, that is what API proposes for those cases, when you have multiple Activities with common state.
