Hello All,
I am trying to write some test code to receive RSS feeds. I am using the
ROME api's. But I am getting a exception when executing the following line
of code
SyndFeed feed = new SyndFeedInput().build(reader);
I googled this exception and found the following. I dont know if thats
helpful or not. Please advice me on my next steps.
"Ok, I figured it out after traversing through the Rome code.
ClassLoader isn't supported by Android's DalvikVM. Is there an
implementation of this project that doesn't use ClassLoader?"
