Official Driving Rules & Road Signs Android App
Traffic Quiz App is a native Android application built with Java and XML. It provides interactive quizzes, road sign flashcards, timed mock tests, and instant score feedback to help users prepare for official driving license exams.
Driving license candidates often struggle to memorize dozens of road signs and safety rules without interactive practice materials.
Engineered an intuitive mobile testing app with category-wise quizzes, real-time score calculation, and local offline persistence via Room DB.
/ TECHNICAL BREAKDOWN
Built using MVVM (Model-View-ViewModel) architecture pattern, separating UI components from business logic and database management.
Ensuring fast quiz rendering without lag while handling hundreds of high-resolution vector road sign graphics.
Mastered Room Database migrations, LiveData observer patterns, and efficient image caching in Android Studio.
This application complies with Google Play Developer Program Policies, user data safety standards, and transparent privacy disclosures.
