i have plan to convert our site to android app with webview.is it possible to make Virtual Tour work in Offline in App ? so users can download virtual tour for view offline ?

Webview doesn't support WebVR so that won't work.

I assume you want to do this in a headset? "Easy" solution is to load the content locally. Run a local server and view it in a browser pointed to the local content. Check this thread: Oculus GO: Working Apache PHP Mysql server
