Cannot use jsoup in Android Studio

Issue

I tried installing jsoup using this video

Then, a bunch of issues appeared, one after the other:

first thing

happened twice, for other files

fixed by ending java in task manager

fixed by clicking run after clean

After fixing all that, I tried running my test app (this is my MainActivity)

package babis.querytest;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;

import java.io.IOException;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Log.i("qt","before");
    try {
        Log.i("qt","before1");
        Document doc= Jsoup.connect("http://www.google.com").get();
        Log.i("qt","after0");
    } catch (IOException e) {

    }
    Log.i("qt","after");
}
}

My Logcat is this

</manifest>

the app crashes on the Document line. what is the issue?(wifi is working)

Solution

you have to run it in an async task not on the main thread

 new AsyncTask<Void, Void, YourDataObject>() {
            @Override
            protected YourDataObject doInBackground(Void... params) {
                Document doc= Jsoup.connect("http://www.google.com").get();
                // parse the document here and return what ever data you want
                return myFunData;
            }

            @Override
            protected void onPostExecute(YourDataObject data) {
                //update UI based on results of parsing html
            }
        }.execute((Void) null);
