Overview

StudyBuddyIT is a simple, beginner-friendly flashcard app built with Kotlin and Jetpack Compose. It lets you quickly create, review, shuffle, and delete flashcards to aid your study sessions. On launch, you’ll see any saved flashcards; tap Show Answer to reveal the answer, Next Card to cycle through, Shuffle to randomize the deck, and long-press a card to delete it. If you have no cards yet, a friendly “No Cards – Please add flashcards” prompt guides you to start creating your own.

I created StudyBuddyIT to deepen my understanding of modern Android development. Particularly Jetpack Compose for UI, Material 3 theming, and simple on-device persistence via SharedPreferences

• Gson. Along the way I practiced Kotlin data classes, state management in Compose, Activity
• result APIs, and designing a clean, responsive and accessible layout.

Development Environment

• IDE: Android Studio
• Language: Kotlin
• UI Toolkit: Jetpack Compose (Material 3)
• Persistence: Android SharedPreferences with Gson for JSON serialization
• Testing: JUnit4 for local JVM tests
• Build System: Gradle Kotlin DSL

Useful Websites

• Jetpack Compose – official guide for Compose basics and Material 3.
• Material 3 for Android – color theming, typography, and component specs.
• Android Developers: Activities and Intents – how to launch Add-Card screen and handle results.
• Android SharedPreferences – storing simple JSON blobs on-device.
• Gson User Guide – serializing Kotlin objects to/from JSON.
• Kotlin Data Classes – auto-generated equals/hashCode/toString.
• Android Testing on the JVM – writing fast unit tests for non-Android code.

Future Work

• Room database integration – replace SharedPreferences + Gson with a cleaner/ more modern data persistence option.
• Search & categories – tag flashcards by topic and add a search/filter capability to the UI.
• Device configuration handling – preserve deck state on device rotation.
• Theming options – user-selectable light/dark or custom color palettes.
• Cloud sync – back up decks to Firebase or a REST API for cross-device use.
• Accessibility improvements – better screen-reader support and adjustable font sizes.
