LESSON OUTLINE
Concepts

- Users should remember they have access to the back-swipe gesture as implemented on all contemporary Android devices. This allows users to navigate out of the wrong screen or menu with greater speed.
- Navigation patterns in web app grids
- Grids & columns contain a Search Bar.
- Grids expose a Query Builder for multi-clause filtering.
- Navigation patterns in the Scanner App
- Main Menu Grid is the primary entry point.
- Menu Drawer lets you switch workflows without returning to the Main Menu.
- User icon menu provides User Settings and Logout.
Minimum viable setup
- Scanner App: confirm instance is set (admin setup)

- If you see a Setup screen, use the setup barcode to configure the correct instance.
- Confirm you can reach the Splash Screen, then the Login Screen.
