This is a pretty simple question, but I have been unable to find anyway to accomplish what I am trying to do…
I want to launch a new Activity to display some complex information. Because of the complexity, it is undesirable to serialize the information into the intent’s parameters. Is it possible for the the new Activity to get a reference to the launching activity, so it can call its methods?
If you use a custom application class, you can store information that will be kept between the activities.
See a tutorial here for instance.
