For Android, maybe you can try creating a new android project with Eclipse/IntelliJ Idea, then add a Webview layout, then move your code tu /assets folder and finally create a webview object and put your URL on the method called loadUrl WebviewOb.loadUrl("file:///app/asset/file.html"), don't forget to add setContentView(WebviewOb)...

or instead of doing a android project you can use PhoneGap (Android/IOS/BB). I never used it, but in the website says that's so easy like 1-2-3.

Yeah, as pointed by Ulises Ponce Mendonza, PhoneGap is the best option. Its compiler converts your html code into corresponding Iphone, android ,BB apps. i ve tried it some time ago, all you have to do is paste your code in one index.html file in the default project workspace.

Try cordova https://cordova.apache.org/

As fas as I know, PhoneGap is one of the most popular packager for application built based on mobile devices Web Kit. You can build apps for various mobile platform using the same HTML source.
