Remarks

Called when the activity needs its list of headers build. By implementing this and adding at least one item to the list, you will cause the activity to run in its modern fragment mode. Note that this function may not always be called; for example, if the activity has been asked to display a particular fragment without the header list, there is no need to build the headers.

Typical implementations will use #loadHeadersFromResource to fill in the list from a resource.
