Fragment layout option

On the page where the Activity name and navigation type are displayed a fragment layout option is also displayed? What is it used for? Probably this option is coming due to the new version of Eclipse and ADT

Fragments form a part of the UI just like regular activities can, the difference being that a single activity can display multiple fragments on one page (eg. a multi-pane UI) and multiple activities can re-use the same fragment.

Fragments, however, do depend on being embedded in an activity, so you can either use just activities or both activities and fragments. This is why when you create a blank Android project in Eclipse there will be both an activity_main.xml and a fragment_main.xml. The latter is actually what the user will see, while the former is simply used to anchor the fragment to it. You can read more about fragments here.

They were added by default in the newer versions of the ADT for Eclipse - this is why the Android course here doesn't include fragments initially, since the videos were released only months before the ADT was updated.
