You would use a Web View if you want to build the basic page/content surrounding the panorama in InDesign (See the guide, you would just direct it to your HTML page, allow user interaction, and set to auto play.) You could also just upload a html page by itself as an article (and not use a Web View/InDesign page.)
In either event, they will use Mobile Safari to render the HTML page within a viewer viewport window.
OK Thanks Casey -
I think Uploading html page as an article sounds reasonable - I will test it during this weekend
I hope that would make panorama work on Android devices ..
