Build & Test Commands

• Build Debug APK: ./gradlew assembleDebug
• Build Release APK: ./gradlew assembleRelease
• Clean Project: ./gradlew clean
• Run Unit Tests: ./gradlew test (if applicable)

Code Style Guidelines

• Language: Kotlin 1.9+
• UI Framework: Traditional Android View system (XML layouts), not Jetpack Compose.
• Naming Conventions:
  • Classes: PascalCase (e.g., CountdownDialog)
  • Functions/Variables: camelCase (e.g., startTimer())
  • Layout Files: snake_case (e.g., activity_main.xml)
  • Resource IDs: snake_case (e.g., btn_start)
• Android Patterns: Use findViewById for view binding in this project to maintain consistency with existing simple architecture.

Architecture

• Pattern: Simple Activity-Dialog architecture.
• State: The countdown state is managed locally within CountdownDialog using android.os.CountDownTimer.
• Dependency Management: Gradle with Groovy DSL.
• Key Constraints:
  • The CountdownDialog is explicitly set to setCancelable(false) and setCanceledOnTouchOutside(false) to ensure the timer completes.
