Original issue reported on code.google.com by webe...@gmail.com on 23 Mar 2014 at 9:53

I just started playing around with the source code and hit this error as well.

Cause: The 'layout' field of the story is not being set by 
Story.createNprmlStory(Node node), as the xml returned by the server and fed 
into this method does not contain a 'layout' node.

Not sure if this is a server side error or if the XML format changed at some 
point and this application wasn't updated.

The null pointer exception is being thrown in NewsStoryActivity.loadStory on 
the following line:

     if (story.getLayout().getItems().size() > 0) {

The solution is easy: check the value of getLayout before using it :-) The 
accompanying else looks like it already includes code for handling cases where 
the layout is missing.

I will try it out and submit the fix.
