Hi guys, new here and new to programming.  I've been using Stack Overflow, but I'm realising they aren't so tolerant with someone like myself asking lots of newbie questions, even though I've done hours of searching for my answer.

Anyway, to my issue.  I am writing an Android app that in part of it I would like to download traffic information.  I have a link to an xml file I can use - http://m.highways.gov.uk/feeds/rss/AllEvents.xml

For now though, I've downloaded this xml file and put it in my res folder.  I'll come to parsing it without downloading if we can fix the first issue

Now, at the moment I have a SAXHandler that looks like this -



Then in my main activity I have -



The error I get is -

org.apache.harmony.xml.ExpatParser$ParseException: At line 1, column 0: syntax error

So it looks like me first issue is my parser doesn't like the xml format?

If we can figure that, I would like to then know how to a) download this xml as the user opens the activity or b) parse it direct?

Thanks for any help you might be able to offer a struggling noob!

A StringReader uses as its input the string used to create it. That would be "allevents.xml" rather than the contents of the file called "allevents.xml". I think you need a FileReader instead.

As to the Android-related question, please start a separate topic in the Android forum.

Thanks.  Makes sense.

I've made that change, I've tried moving the xml into an xml folder in Res and changed the code to be new FileReader("xml/allevents.xml") but I still get -

java.io.FileNotFoundException: xml/allevents.xml (No such file or directory)

Where should the file be?

That's not how files are accessed in Android. Files should go into the "raw" directory, and then you would access them via something like this:


Please post any further Android-specific follow-up questions to the Android forum.
