Having a quick look at the code, it looks like there must have been an error parsing the XML feed - the exceptions caught all have a very basic log statement which might give you some clue, but you might need to add more logging or step through with a debugger.

Basically - from that stack trace, the NullPointerException is coming from line 52 in RssService.java - which means the variable articles is null. This variable is passed through and is the returned result from the method in that class doInBackground - you will see that the only scenario in which the return null happens is if the try block fails to get to the end.

It all needs better exception handling - but to get to the bottom of the error just check what error is being thrown in that method.

Hi Rob,

Can you please reach out, I'm having an issue returning the view on my galaxy s6? Have you ever had this issue?

@bigsteve4288 do you have more of the logs or a stacktrace? I can't see any details of the error in that log.

The parser is not returning any articles from http://www.espn.com/espn/rss/news

So I'm thinking its something I'm doing wrong with the parser
