How to use AsyncTask correctly in Android [closed]

Answer 1

According to AsyncTask, its

 AsyncTask

• Params, the type of the parameters sent to the task upon execution.
• Progress, the type of the progress units published during the background computation.
• Result, the type of the result of the background computation.

So if you want to pass void in doInBackground just pass void in place of Params.

Example code:

class DownloadLink extends AsyncTask {


        @Override
        protected Void doInBackground(Void... params) {
            // TODO Auto-generated method stub

            //Do Your stuff here..
            return null;
        }
    }

And call it as:

 new DownloadLink().execute();
