Android Program Error
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

public class NewsActivity extends Activity {
WebView mWebView;

try {
writing = Jsoup.connect(link).get();
} catch (IOException e) {
e.printStackTrace();
}
Element heading = writing.select("h2").first();
Elements classname = writing.getElementsByClass("news");
Elements items = classname.select("p");
full = full + heading.text() + "<br>" + items.get(0).text() + "</td></tr>";

String newImg = "<img src=\"" + picture + "\"/ width =100 >";

full = full + "<tr><td>";
for (int i = 1; i< items.size(); i++)
{
full = full + items.get(i).text();
}
full = full + "</td></tr></table></body></html>";
return full;

public void main(String... args)

setContentView(R.layout.main);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.setWebViewClient(new NewsClient());
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setDomStorageEnabled(true);
mWebView.loadData(test2, "text/html", "utf-8");
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}

public boolean shouldOverrideUrlLoading(WebView view, String url) {
String newUrl = text(url);
view.loadData(newUrl, "text/html", "utf-8");
return true;

}
}
My guess is that the missing closing anchor tags are causing problems. I'm guessing the HTML parser doesn't like empty anchor tags:
String temp2 = "<a href=\"" + temp + "\"/>";
String newImg = temp2 + "<img src=\"" + url + "\"/ width =100 >";
test2 = test2 + "<tr>";
should be:
String temp2 = "<a href=\"" + temp + "\" >";
String newImg = temp2 + "<img src=\"" + url + "\"/ width =100 >" + "</a>";
test2 = test2 + "<tr>";
and:
test2 = test2 + " " + txt.get(i-1).text() + " " + temp2;
should be:
test2 = test2 + temp2+ " " + txt.get(i-1).text() + " </a>";
加载中,请稍侯......
