import java.net.URL;

public class MainActivity extends Activity {

    // XPath query
    static final String XPATH_STATS = "//div[@id='blog-stats']/ul/li";

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // decide output

        // create URL object
        URL url = new URL(BLOG_URL);
        // get HTML page root node
        TagNode root = htmlCleaner.clean(url);

        // query XPath
        Object[] statsNode = root.evaluateXPath(XPATH_STATS);
        // process data if found any node
        if(statsNode.length > 0) {
            // I already know there's only one node, so pick index at 0.
            TagNode resultNode = (TagNode)statsNode[0];
            // get text data from HTML node
            stats = resultNode.getText().toString();
        }

        // return value
        return stats;
    }
}

Error exits

Answer 1

After ((TextView)findViewById(R.id.tv)).setText("Error"); add Log.e("Error", ex);
This will print out the full exception for you and it will be clear what went wrong.

Answer 2

try {
            value = getBlogStats();
            ((TextView)findViewById(R.id.tv)).setText(value);
        } catch(Exception ex) {
            ex.printStackTrace(); //ДАЛЕЕ ВЫЛОЖИТЕ ЛОГИ, вряд ли кому захочется вникаться в код
            ((TextView)findViewById(R.id.tv)).setText("Error");
        }
