## Overview

Quiz das Bandeiras is a small Android flag-quiz app. The user enters a name, answers a fixed sequence of flag questions, and sees a final score and name; results allow restarting or returning to the main screen. Activity source shows the screen transitions and intent data. The tree lists the layouts, but the referenced flag image resources are not present in the supplied tree, so they are omitted.

Main entry points: [`app/src/main/java/br/edu/fatecgru/ResultadoActivity.java`](https://github.com/giovanni-fm/quizdasbandeiras/blob/main/app/src/main/java/br/edu/fatecgru/ResultadoActivity.java) (Results screen), [`app/src/main/java/br/edu/fatecgru/MainActivity.java`](https://github.com/giovanni-fm/quizdasbandeiras/blob/main/app/src/main/java/br/edu/fatecgru/MainActivity.java) (Name screen), [`app/src/main/java/br/edu/fatecgru/QuizActivity.java`](https://github.com/giovanni-fm/quizdasbandeiras/blob/main/app/src/main/java/br/edu/fatecgru/QuizActivity.java) (Quiz screen), [`app/src/main/res/layout/activity_main.xml`](https://github.com/giovanni-fm/quizdasbandeiras/blob/main/app/src/main/res/layout/activity_main.xml) (Name layout)
