ADenv
Android Deploy environment
HTML application wrapper, creates a directory (usually at /storage/emulated/0/) called ADenv, and a file called ADenv.html, replace this HTML with the one you want (name must be ADenv.html), it will generate a 'working copy', allowing you certain modifications at runtime, if data is important, make copies of ADenv.saved.html often, as sometimes files are "corrupted". Also a properties file can be in the directory, to force some settings (orientation and scale), it's optional, but can help you...
