Late Entry Project

  • Barcode scanner Android application, based on MVVM Architecture
  • An offline friendly app
  • Handled edge cases related to multiple clicks, multiple toasts, asking user permission, etc.
  • GitHub Actions & Firebase App distribution for CI/CD to reduce testing time by 20%
  • Implemented R8 to reduce apk size by 28.5%

Purpose 📌

This app is created for an official purpose currently being used in our College, in order to easily keep a track on students coming late to the college. The app data is synced with a remote server, where data is stored permanently.

Functionality 💻

  • The user must authenticate himself first in order to start scanning
  • The app provides a quick barcode scanner, with an option to enable flash
  • In case of damaged camera/barcode, the user can manually enter student number and register a late entry
  • On scanning or manually entering data, student details pops up with name, branch, admission year, image, & student no (which are stored in app's database to provide quicker access)
  • In offline scenario, all entries are stored in app's database, & can be synced with the server afterwards
  • The Settings page include the option to sync locally stored student details & late entry records and other options related to the user
