Fuzzy Time GB

A minimal word-based Watch Face Format face for Wear OS. It displays fuzzy British English time phrases based on the C logic from the Pebble watchface fuzzy-time-gb.

The Android app module is resource-only: android:hasCode="false" and WFF version 2. The helper script in tools/ regenerates the declarative XML, but it is not packaged into the watch face APK.

The optional Arvo style bundles the Arvo typeface, licensed under the SIL Open Font License 1.1. See licenses/Arvo-OFL.txt. Release asset generation also vendors Liberation Sans under the same license; see licenses/LiberationFonts-OFL-1.1.txt.

Build

The project uses Gradle 9, Android Gradle Plugin 9, and Watch Face Format v2. Gradle is configured to run the build daemon with a JetBrains JDK 21 toolchain from gradle/gradle-daemon-jvm.properties; if a matching JDK is not available locally, Gradle can provision one via the Foojay resolver configured in settings.gradle.kts.

./gradlew :watchface:assembleRelease

On local machines that do not have ANDROID_HOME configured globally, point the wrapper at your Android SDK:

env ANDROID_HOME=/var/home/nedr/Android/Sdk \
  ANDROID_SDK_ROOT=/var/home/nedr/Android/Sdk \
  ./gradlew :watchface:assembleRelease

Release APKs deliberately use the Android debug/test key for developer installs. For an isolated installation alongside a differently signed existing copy, use :watchface:assembleDeveloper (package suffix .dev). An unsigned App Bundle for future Play signing is available with :watchface:bundlePlay; it is never published automatically.

Regenerate Watch Face XML

python3 tools/generate_watchface.py

Regenerate Release Assets

python3 tools/generate_release_assets.py

Check watch face behaviour and resource budgets

python3 -m unittest discover -s tools -p 'test_*.py'
python3 tools/check_watchface.py
python3 tools/validate_memory.py

The memory command checks the release APK and downloads Google's evaluator with a pinned SHA-256. check_watchface.py estimates a conservative ambient glyph bound and checks circular text fit; pass --system-font /path/to/device-font.ttf to check a particular watch. Neither check replaces on-device testing.

For reproducible device tests without changing the watch clock, use python3 tools/device_fixture.py --time 12:25 --font arvo --range 0 100 66, then build/install the developer variant. Run python3 tools/device_fixture.py --clear and rebuild afterward. Fixtures affect only the developer variant.

Validate WFF

python3 tools/validate_wff.py
