Android onPostExecute not been recognize

This is my code: 

//.___ Async task bring info from API __./
AsyncTask asyncTask = new AsyncTask() {
    @Override
    protected Object doInBackground(Object[] objects) {
        mMovieDto = mDataSource.getPopularMovies();
        return null;
    }

    @Override
    protected void onPostExecute(Long result) {
        fillList();
    }
};
asyncTask.execute();

I'm getting the error that the onPostExecute is not overriding from super, witch is the right way to add this king of method to my AsyncTask?

Thanks for the help Jose

You are missing the AsyncTask's generic types:

The three types used by an asynchronous task are the following:

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

Not all types are always used by an asynchronous task. To mark a type as unused, simply use the type Void:

private class MyTask extends AsyncTask<Void, Void, Void> { ... }

Change your code like this:

AsyncTask asyncTask = new AsyncTask<Void, Void, Void>() {

    @Override
    protected Void doInBackground(Void... params) {
        mMovieDto = mDataSource.getPopularMovies();
        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        fillList();
    }
};
asyncTask.execute();
