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.

当您有多个具有公共状态的活动时，您可以使用Application对象，即API为这些情况提出的建议 。
