i found this on the page you mentioned :-
"Note a few limitations on using loader layouts:
1. Loader layouts are not shown when publishing as native apps on mobile (e.g. via PhoneGap, CocoonJS and appMobi). This is because the entire application is downloaded at once. Since all files are immediately available, nothing needs to be downloaded. For these platforms you probably want to focus on a custom splash image instead."
so what about intel xdk ?!
