What is the proper way to make my List be read and modified throughout my entire Android Java project?
===

I have the following List:

    List<Map<String, String>> items = new ArrayList<Map<String, String>>();

It's populated with data on the load of my app. I need to use it throughout my entire app, on most Activities and Fragments, with data both being read and being modified.

What is the best and simplest way to make this global without too much complexity?

Note: For reasons that are too much to explain on Stack Overflow, this much be used a List and not as a custom Object with properties.
