安卓程序错误
我已经编写了这个 Android 程序作为新闻提要...它运行良好，直到 - 目前 - 关于 focus.ie 的文章。所以前 6 个故事加载得很好，但随后就无法加载其余的故事，我绞尽脑汁试图找出原因。任何帮助将不胜感激。这是代码。谢谢

I've written this Android program as a news feed...it works fine up until - currently - the article about focal.ie. So the first 6 stories load fine but then it doesn't load the rest and Im wrecking my head trying to figure out why. Any help would be appreciated. Here's the code. Thanks
