How to Fix Jsoup nullpointerexception in android studio 2019

Question

I am creating an app in which i want to scrape google data with the help of jsoup and show it to text view in android studio.

But after doing some coding with the help of jsoup i am getting following error:

E/AndroidRuntime: FATAL EXCEPTION: AsyncTask #1
Process: com.example.yasht.cricketapp, PID: 11929

this is my jsoup code with async task :

    public class score_scrape extends AsyncTask<Void,Void,Void> {

 String words;
 TextView score;

public score_scrape( TextView score){
    this.score =score;

}


    @Override
    protected Void doInBackground(Void... voids) {

        try {
            Document doc = Jsoup.connect("https://www.google.com/search?q=india+vs+australia+3rd+odi+live+score").get();
            Element element = doc.select("div[imspo_mh_cricket__score-major]").first();
            words = element.text();

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


        return null;
    }

    @Override
    protected void onPostExecute(Void aVoid) {
        super.onPostExecute(aVoid);
        score.setText(words);
    }
}

I am using async task method which is declared i my main activity.

Comment for any further information.

Your `element ` return null and your `doc.select` wrong you are not following hierarchy. — soorapadman, Jan 21 '19 at 13:11

In your case you don't want to use select You can simply change below line.

Change line from

Element element = doc.select("div[imspo_mh_cricket__score-major]").first();

To

Element element = doc.getElementsByClass("imspo_mh_cricket__score-major").first();

Output:
