AsyncTask not working properly

Issue

Here is my problem. I have noticed that my AsyncTask does not work properly. What I mean is, even if I run this code:

@Override
protected void onProgressUpdate(Integer... values) {
    super.onProgressUpdate(values);
    progress.setText(values[0] + "%");
}

@Override
protected Void doInBackground(Void... voids) {
    for (i = 0; i <= 100; ++i) {
        publishProgress(i);

        try {
            Thread.sleep(10);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        Log.i("progress", i + "");

    }
    return null;
}

it does not seem to do antything at all and after 5 seconds (or even more) my progress alomost instantly goes from 0 to 100%, even though it should wait for 10ms between every call of publishProgress(). Is it something that I'm missing?

Solution

What I think is a thread problem , because AsyncTask automatically creates a new Thread for you, so everything you do in doInBackground() is on another thread. So start "sleep" onPreExecute() and finish onPostExecute()
