CI / ci (push) Successful in 14m34s
- skip setup-android's default packages (pulled the ~300 MB emulator every run) - drop unused platforms;android-36 and the dead jq install step - cache /opt/android-sdk and ~/.gradle (release.yaml had no cache at all) - drop --no-daemon so lint/test/assemble reuse one warm daemon per job - Trivy scan only on main (advisory-only; was ~25s tax on every branch push) - concurrency group cancels superseded runs; drop duplicate pull_request trigger Companion to the act_runner fix on the CI host: job containers now join the runner's network so the actions/cache server is reachable (saves previously failed with reserveCache timeouts, so no cache was ever stored).

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
