A native Android application developed in Java that implements a structured multiple-choice testing system with user interaction, navigation flow, and state management.
Developed as a team semester project (MSc ICT – University of West Attica).
This application simulates a structured test environment where users:
- Log in
- Answer multiple-choice questions
- Navigate through questions
- View final results
- Track progress dynamically
The project focuses on Android fundamentals, UI interaction, activity lifecycle handling, and clean application flow.
