Second slice of milestone 2 (write support): - EventForm domain model + problems() validation (end-before-start, no-calendar; blank titles and instant events stay legal) - Full-screen EventEditScreen: title, all-day switch, M3 date/time pickers (moving the start preserves the duration), calendar picker limited to writable calendars, location, description. Save validates, requests the WRITE upgrade contextually, and closes on success - Calendar preselection: explicit pick > last-used (CalendarPrefs) > first writable calendar - insertEvent in the data source; EventWriteMapper (JVM-tested) normalises all-day events to UTC midnights with exclusive DTEND, timed events to the device zone - CalendarFabColumn shared by month/week/day: persistent "+" FAB anchored on the visible day, jump-to-today pill stacked above it - Tests: EventForm validation, write-time mapping (incl. DST-safe epoch check), repository createEvent delegation/error propagation Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Calendula
A modern Material 3 Expressive calendar app for Android.
Calendula is named after the flower of the same name, whose name comes from
the Latin kalendae — the first day of the month — the same root as the
word "calendar". Calendula reads from Android's built-in CalendarContract,
so any calendar source synced to your device (CalDAV via DAVx5, Google,
local, WebCal subscriptions, ...) is shown.
Features (V1)
- Month, Week, and Day views
- Read-only event details (write support comes in V2)
- Multi-calendar visibility toggle
- Material You Dynamic Color (Android 12+)
- Light/Dark theme follows system
- German + English UI
Building
Requires Android SDK 36 and JDK 17. The Gradle wrapper is checked in, so no host Gradle install is needed:
# Build debug APK
./gradlew assembleDebug
# Run unit tests
./gradlew test
# Run lint
./gradlew lint
If your default JDK is something other than 17, set JAVA_HOME explicitly:
JAVA_HOME=/path/to/jdk-17 ./gradlew assembleDebug
