If you need a global object like that, the best thing to do is to hold a reference to it in your application class object, which you can access from any activity via getApplication(); Just be sure that whatever you are sticking in that map isn't keeping a strong reference to the activity context, otherwise you'll start leaking activities across lifecycle events.
