Question

The onProgressUpdate() is never called, can you tell me why?

private class LoginMe extends AsyncTask<Context, Void, Boolean> {

    @Override
    protected Boolean doInBackground(Context... arg0) {
        doSomething();
        return true;
    }

    @Override
    protected void onProgressUpdate(Void... v) {
        super.onProgressUpdate(v);
        Log.d("Dev", "Im in onProgressUpdate()");
    }

    @Override
    protected void onPostExecute(Boolean result) {
        super.onPostExecute(result);
        if (result) {
            doOne();
        } else {
            doTwo();
        }
    }
}

You have to call publishProgress from within doInBackground manually.

doInBackground(Params…), invoked on
the background thread immediately
after onPreExecute() finishes
executing. … This step can also use
publishProgress(Progress…) to
publish one or more units of progress.
These values are published on the UI
thread, in the
onProgressUpdate(Progress…) step.
