Answer 1

Oh sure. Bundle all your HTML, JS anc CSS with your app, and have a thin Java/Android app over these assets. If you are not making any calls to fetch or show external HTML/pages, you don't need internet.

Answer 2

Most likely no.

While it is possible to run "web apps" without access to the internet (you can simply execute Javascript locally from some browsers), it would be

• (Subjectively) not particularly useful.
• Not supported by many devices, whom (like the iPhone) do not allow the storage and execution of arbitrary, non-native code on the device.

However, some frameworks do exist that hold the idea of "web apps" can be a distribution model. For example, PhoneGap allows you to code in HTML5/Javascript, and distribute your app to multiple platforms.
