This Android app is built with the Kotlin programming language and provides a complete fast food menu with billing and Paypal included. The app itself is a demonstrator so the billing system has been deactivated but allows the user to choose food and complete an order before giving the option to view a user journey of the billing system with Paypal which has been completed and documented on the electronic portfolio site Behance using Paypal's sandbox functionality or alternatively the user can return to the main menu.
