Android :: Android.app.Application Global Application Variable Store

I want to create a global variable store for a list of user defined objects. I have a LinkedList of Feed (a user defined object) that I need to be made available to a new Activity that is created. This list is displayed using a ListView and so when an item of the ListView is clicked, I need the correct Feed index to be 'passed' to the new Activity. I have no problem doing this as I create an Intent and then pass the id of the selected row. I need the new Activity to have access to the LinkedList of Feed objects.

There are different ways to do this (explained here - http://code.google.com/android/kb/framework.html). I want to use the option (quoted from link above): The android.app.Application class The android.app.Application is a base class for those who need to maintain global application state. It can be accessed via getApplication() from any Activity or Service. It has a couple of life- cycle methods and will be instantiated by Android automatically if your register it in AndroidManifest.xml.

I want to use the above method as I could then fill the LinkedList at application start and then use it throughout without any duplicates etc. Does anyone know how the android.app.Application class can be used as a global variable store that can be accessed from other classes? I cannot find any more information on this method of passing information between Activities within a single application. Any information regarding passing user defined objects would be useful and specifically how to get the above idea to work.
