I would like to copy this app (its mine) [login to view URL] for android
it is basically made up of many web views, but uses native features like uploading an image to PHP, showing a map and uses a free QR code library.
On the web pages there is are some tab bars for navigation at the bottom.
you can find a movie of the app [login to view URL]
It is your responsibility to review the features and make sure you can emulate them exactly.
