I'm trying to apply the build a blog reader application to my own blog. I populated my own JSON data here: http://www.evotechmachine.com/api/get_recent_posts/?count=10

The data is organized almost exactly as the teamtreehouse example. I checked to make sure names are the same and they are. The only thing that I thought I would need to change would be this line:

URL blogFeedUrl = new URL("http://www.evotechmachine.com/api/get_recent_posts?count=" + NUMBER_OF_POSTS);

I changed the NUMBER_OF_POSTS member variable to reflect the 10 posts that I wanted. According to the logcat I'm running into a problem here:

int contentLength = connection.getContentLength(); char[] charArray = new char[contentLength];

Not a big deal, but If someone has an inkling of what I'm doing wrong Id appreciate it.

It's most likely a content length problem. Log the content length and tell me your output.

Log.v("TESTING", contentLength);. If you get -1 there, then that's your problem. Content length is optional to be sent by a server. A lot of dynamic servers (I believe won't set this). Such as some google json outputs you can fetch.

EDIT: Seems you are not the first with this problem. Follow along with this thread and it should help you: https://teamtreehouse.com/forum/problem-in-the-getcontentlength-function?sort=my-posts

I haven't quite solved the problem yet, but I think I know what the problem is. I think there is a limit to the charArray[] and too much data is being fed into it. I'm looking for a better way to parse the JSON data (maybe I should just watch more of the videos for this topic....)
