Parsing HTML in android using Jsoup

Question

I'm trying to parse HTML into android using Jsoup. When I'm trying to connect to url, I get error

Document doc = null;  
        try {
            doc = Jsoup.connect("http://en.wikipedia.org/").get();
        } catch (IOException e) {
            e.printStackTrace();
        }

Errors:

12-08 13:27:11.254 28041-28041/? E/dalvikvm: Could not find class 'android.graphics.drawable.RippleDrawable', referenced from method android.support.v7.widget.AppCompatImageHelper.hasOverlappingRendering

can you post your main activity xml code as well as your whole MainActivity java code? — Darush

This error doesn't say anything about Jsoup. It is related to your xml code. — Darush

i think your problem is in android.graphics.drawable.RippleDrawable tag in XML please post your xml file here — Saif

There is an xml file. I'm not using android.graphics.drawable.RippleDrawable — Morthan

this works for me :

 button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            new JsoupParser().execute();

        }

    });
}
public class JsoupParser extends AsyncTask<String,Integer,String> {
    String title;
    String s = editText.getText().toString();//get url from EditText 
    Document doc;

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        textView.setText("");
    }

    @Override
    protected String doInBackground(String... params) {
        try {
            doc = Jsoup.connect(s).get();
            title = doc.title();

            }
        catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(String result) {

        textView.setText(title);
    }
