It works very well I do not understand your problem.

An example of implementation in a AsyncTask:

import android.os.AsyncTask;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

import com.mikhaellopez.circularfillableloaders.CircularFillableLoaders;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        CircularFillableLoaders circularFillableLoaders = (CircularFillableLoaders) findViewById(R.id.circularFillableLoaders);
        new CircularFillableLoadersAsyncTask(circularFillableLoaders).execute();
    }

    private class CircularFillableLoadersAsyncTask extends AsyncTask<Void, Integer, Void> {
        private CircularFillableLoaders mCircularFillableLoaders;

        public CircularFillableLoadersAsyncTask(CircularFillableLoaders circularFillableLoaders) {
            mCircularFillableLoaders = circularFillableLoaders;
        }

        @Override
        protected void onProgressUpdate(Integer... values) {
            int progress = values[0];
            mCircularFillableLoaders.setProgress(progress);
        }

        @Override
        protected Void doInBackground(Void... params) {
            for (int progress = 0; progress < 100; progress++) {
                try {
                    Thread.sleep(200);
                    publishProgress(progress);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            return null;
        }
    }
}
