I scoured this site for the last two days looking for a reason why this will not function properly! I am trying to get the workout of the day on crossfit.com, when I run the program it displays a white screen for a while then crashes. Please advise me on what is wrong here!!

public class MainActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    TextView tv = (TextView) findViewById(R.id.textView1);

    Document doc = null;
    try {
        doc = Jsoup.connect("http://www.crossfit.com").get();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    Element content = doc.getElementsByClass("blogbody").first();
    System.out.println(content.text());
    tv.setText(content.text());
}
}

    Well, .. Jsoup is not flawless. While it’s one-size-fits all downloads seem appealing you’re sometimes better off downloading the stream yourself.

    URL url = new URL("http://www.crossfit.com");
url.openConnection();
InputStream is = url.openStream();
byte[] b = new byte[8192];
int count;
ByteArrayOutputStream os = new ByteArrayOutputStream();
while ((count = is.read(b)) != -1) {
    os.write(b, 0, count);
}
is.close();
doc = Jsoup.parse(os.toString("UTF-8"));

    It’s a pretty huge page – shitting out about 70k of HTML per pop is not going to sit well with a DOM-like model in any small memory print device. Loading it yourself could work .. on most devices.. otherwise – look into a streaming solution using TagSoup instead.
