> There's some weirdness around android browsers refusing to load html from the phone itself on security grounds OP here - I have been able to open single .html files on Android (browser uses 'content://' and not HTTP in the address bar; my initial attempt at a portable mobile knowledgebase was FeatherWiki, which is single-HTML. For HTML pages that referenced scripts or external images, it would only work on Android if I had an HTTP server app running. The SimpleHTTPServer app on Android is free and works for this.
