An error occurred while executing doInBackground(), don't know what is wrong

Question

I am still new to Android programming and trying to get my head around the AsyncTask() concept, though i have understood a lot, this one error is bugging me for a really long time. Please provide your valuable suggestions. I have made a weather app which using jsoup and some web scraping, it used to work perfectly and now i am getting this error and don't know what to do. Help is much appreciated.

Here is the code:

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

import android.os.AsyncTask;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import java.io.IOException;

public class MainActivity extends AppCompatActivity {

    static TextView weatherInfo;
    TextView x_view;
    TextView y_view;
    EditText x_edit;
    EditText y_edit;
    Button submit_button;
    String cord_x;
    String cord_y;
    String f_coord;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        weatherInfo = findViewById(R.id.weather_info);
        x_view = findViewById(R.id.X_View);
        y_view = findViewById(R.id.Y_view);
        x_edit = findViewById(R.id.x_edittext);
        y_edit = findViewById(R.id.y_edittext);
        submit_button = findViewById(R.id.submit_button);
        submit_button.setOnClickListener(
                new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        weatherInfo.setText("");
                        cord_x=x_edit.getText().toString();
                        cord_y=y_edit.getText().toString();
                        f_coord=cord_x+","+cord_y;
                        Weather runner = new Weather();
                        runner.execute(f_coord);
                    }
                }
        );



    }


    static class Weather extends AsyncTask<String, String, String> {
        String result = null;

        @Override
        protected String doInBackground(String... string) {

            try {

                Document doc = Jsoup.connect("https://weather.com/en-IN/weather/today/l/"+string[0]).get();
                for (Element row : doc.select("header[class=loc-container]")) {
                    result=string[0]+" \nLocation: ";
                    result = result+row.text()+" ";
                }
                for (Element row : doc.select("div[class=today_nowcard-section today_nowcard-condition]")) {
                    result = result +"\nWeather Data:\n"+ (row.text());
                }


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

            }
            return result;

        }

        @Override
        protected void onPostExecute(String s) {
            weatherInfo.append(s);

        }
    }
}

Here is the error report:

`java.lang.SecurityException: Permission denied (missing INTERNET permission?)` does it tell you anything? — Vladyslav Matviienko, Jun 27 '18 at 05:02
This is totally ignorance of `LogCat`. the solution is already there `Permission denied (missing INTERNET permission?)`. — ADM, Jun 27 '18 at 06:04

<uses-permission android:name="android.permission.INTERNET" />

Add internet permission in your manifest file like this

<manifest xlmns:android...>
<uses-permission android:name="android.permission.INTERNET" />
</manifest>

You are missing INTERNET permission in AndroidManifest file. Please add below permission in AndroidManifest to fix the issue:

<uses-permission android:name="android.permission.INTERNET" />

Going through the stack trace indicate what kind of permission you need in the manifest file.

     Caused by: java.lang.SecurityException: Permission denied (missing INTERNET permission?)
                          at java.net.InetAddress.lookupHostByName(InetAddress.java:464)

    Caused by: android.system.GaiException: android_getaddrinfo failed: EAI_NODATA (No address associated with hostname)

     Caused by: android.system.ErrnoException: android_getaddrinfo failed: EACCES (Permission denied)

Please add the permission as below and it would sort out

<uses-permission android:name="android.permission.INTERNET" />
