droptank21 : just tested it on my tablet (a samsung galaxy tab 3 10.1"):
a long black screen followed by an error message:
The connection to the server was unsuccessful. (file:///android_asset/www/index.html)"
The thing I found weird was the file:///, I though only "://" could be in a protocol, not ":///"
It's 'file:///'. You can see here: (remove the space)
you can check your apk by using this:
jar tvf YourAPK.apk

If there is no index.html under assets/www, then sth is missing.
