Loader not run in this activity

[beshoo]

Dear support, I add the KProgressHUD in my InitsViews() and call InitsViews onCreate, but the loader on the section i mentioned here is not showing up, and no error return

        if (!prefManager.geRole().equals("0")) {
            hud.show(); //<<===================Not working , it does not shw up , No error return , no force close , but not show up
            String[] user = prefManager.geRole().split(":");

            helpView.loadUrl(Splash.main.getWelcome() + "?name=" + user[0] + "&private=" + user[1] + "&user_id=" + user[2] + "&random=" +
                    getRandomNumberInRange(999, 15000));
        } else {
            hud.show(); //<<===================Not working , it does not shw up , No error return , no force close , but not show up
            helpView.loadUrl(Splash.main.getWelcome());

        }
