Google is deprecating Android AsyncTask API in Android 11 and suggesting to use java.util.concurrent instead. you can check out the commit here

 *
 * @deprecated Use the standard java.util.concurrent or

public abstract class AsyncTask {

If you’re maintaining an older codebase with asynchronous tasks in Android, you’re likely going to have to change it in future. My question is that what should be proper replacement of the code snippet shown below using java.util.concurrent. It is a static inner class of an Activity. I am looking for something that will work with minSdkVersion 16

private static class LongRunningTask extends AsyncTask {
        private static final String TAG = MyActivity.LongRunningTask.class.getSimpleName();
        private WeakReference activityReference;

        LongRunningTask(MyActivity context) {
            activityReference = new WeakReference(context);
        }

        @Override
        protected MyPojo doInBackground(String... params) {
            // Some long running task
            
        }

        @Override
        protected void onPostExecute(MyPojo data) {

            MyActivity activity = activityReference.get();
            activity.progressBar.setVisibility(View.GONE);
            populateData(activity, data) ;
        }     


    }
