Cannot run a background task in andorid studio using AsyncTask - android-studio

Question

I am trying to run a task at background using AsyncTask, but it isn't working
I have tried a lot of solutions but none worked. My code should show me html codes of prothomalo.com at the logcat, but is is not doing that, instead it is showing a lot of errors.
public class BG extends AsyncTask<String, Void, String> {
#Override
protected void onPreExecute() {
super.onPreExecute();
Log.d("myBG", "onPreExecute: ran");
}
#Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
Log.d("myBG", "onPostExecute: ran");
Log.d("myBG", s);
}
#Override
protected String doInBackground(String... urls) {
Log.d("myBG", "doInBackground: ran");
String result = "";
URL url;
HttpURLConnection conn;
try {
url = new URL(urls[0]);
conn = (HttpURLConnection) url.openConnection();
InputStream in = conn.getInputStream();
InputStreamReader reader = new InputStreamReader(in);
int data = reader.read();
while (data != -1) {
char current = (char) data;
result += current;
data = reader.read();
}
} catch (Exception e) {
e.printStackTrace();
return "Something went wrong";
}
return result;
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = findViewById(R.id.button);
text = findViewById(R.id.text8);
BG myTask = new BG();
myTask.execute("https://www.prothomalo.com");
}
}The logcat should show if my background activity has run or not, but it showing a lot of errors
