how to use rhomobile Javascript API in a webview

Hi all,

I'm totally new to zebra. I created a pure webview app, and installed it to Zebra TC8000. Now I want to use rhomobile JS API (like Notification in Rhomobile | Notification ) in the webview to enable Zebra TC8000 to play audio files in sdcards. By any chance, can anybody have experience to use rhomobile JS API in a pure webview app instead of rhomobile application?

Thanks everybody.
