Advanced Restaurant app for Android 

->Samsung Galaxy Store

->Amazon Appstore

The application is used for information service in restaurant operations. It covers the activity of waiters, warehouse and kitchen. All information is stored in a SQLite database named advanceRestorant.db on mobile devices. The information mainly covers the products in the warehouse, the composition and structure of the restaurant menus, the requests of the clients and the formation of their accounts. When installing the app, it asks for permission to access device files, access location, and enter a username. This name should be in Latin because it is entered as part of a file name identifier, for example when sending requests.

Restaurant menus are organized in hierarchical - tree-like structures. Each tree consists of a main folder and in it folders and menu items - the leaves in the tree. The nesting levels of folders within folders and menu items are virtually unlimited. This organization also appears as a directory explorer on computers. In front of each item there is a check box, pressing it expands or collapses the folder tree. The difference with directories on computers is that folder names and menu item names are entered in the user's preferred language.
This organization of restaurant menus is convenient for easily finding menu items when preparing customer requests.

The roads, walls and paths are colored in different colors, which can be selected. The passage is imitated by a moving ball, which moves in several ways: by dragging, by gravity, by saying commands (left, right, up and down), independently and accelerated. The output is a cell the color of the ball. The app has a point-to-point path finder feature.
