Can I run an html/javascript AIR app on Android or iOS?

Is it possible to compile an already-existing HTML/javascript app to install/run it on any mobile OS (Android or iOS, in particular)? I haven't found anything that says it's possible, only instructions for doing it with a Flash/Flex based AIR app.

I have a large html/javascript app, with a lot of value put into it, and my client would like to be able to package it for use on tablets. Ideally, I'd like to be able to not only have it run there, but also be able to "hide" the html/js code from prying eyes, if there's a way to do that.

Thanks much in advance... I've done considerable research trying to get an answer to these questions.
