Although a few years ago (perhaps Android is different now?) I tried to get a non JS 'website' of my research to run on an Android tablet without success - at that time lots of internet posts seemed to report the same problem. I suspect your tablet problem may be slightly different to JS websites not running from hard drive under windows in that Android does not support (or perhaps only limited support) running 'websites' on local storage.
I moved to using a windows 7 netbook or my data on USB stick when away on research trips so gave up trying to get something working on Android.
I would be interested to hear if things have changed.
