Todozy – Tasks & Habits

Minimalist task manager built with a modular Android stack (Java 17, Kotlin 1.9, AGP 8.x, compile/targetSdk 36, minSdk 24) and MaterialComponents.

Architecture & Modules

• Clean Architecture + MVVM, DI via Koin.
• Domain rules in domain/; shared helpers in utility/kotlin-util and utility/android-util.
• UI kit split into ui-component/public (contracts) and ui-component/impl (views/resources).
• Features under feature/<name>/{public,impl} (task-list, task-form, task-history, task-details, alarm, settings, about, splash, navigation) with data/domain/presentation layers.
• Platform integrations (DB, logging, Crashlytics) in platform/impl. Non-transitive R enforced.

Build & Test

• ./gradlew assembleDebug – build the app.
• ./gradlew test – run JVM unit tests across modules.
• ./gradlew ktlintCheck – style check; ktlintFormat to fix.
• ./gradlew checkCrossModuleRImports – guard against importing the app R outside app/.

Tech Stack

• Kotlin coroutines, Flow
• AndroidX: AppCompat/Activity/Fragment, Lifecycle 2.7, Material Components
• Koin 3.x for DI
• Testing: JUnit4, MockK, coroutine-test, Arch core test

UI/UX

• Theme: Theme.MaterialComponents.DayNight.NoActionBar with Material date/time pickers.
• FABs tinted with colorPrimary and white icons; toolbar uses Material toolbar style.

Development Notes

• Follow module boundaries; import resources from the correct module R (UI alias UiR).
• Avoid SimpleDateFormat; java.time is enabled via coreLibraryDesugaring.
• Pre-commit hooks run ktlint; ensure assembleDebug and test pass before PRs.
