Closes #1

Summary

Established the base monorepo structure containing the Android phone application (phone-app/ using Kotlin, Gradle 8.13, AGP 8.7.3) and the Huawei Lite Wearable application (watch-app/ using JS/HML for Huawei Watch GT5).

Required Scope:

  • Build & Dependency Tooling: Configured Gradle 8.13 with Version Catalogs, AGP 8.7.3, Kotlin 2.0.21, and dependencies for Google Play Services Location, Google Maps Places, and Huawei Wear Engine SDK.
  • Design System & Base UI Foundation: Initialized Material Design 3 theme (Theme.Material3.DayNight.NoActionBar), full light/dark color tokens, and base navigation UI scaffolding (MainActivity, Material 3 components, and state preservation) to establish the application's design system and validate layout inflation, view binding, and resource linking.
  • Huawei Lite Wearable Skeleton: Configured DevEco Studio project structure (config.json, settings.gradle, build.gradle, entry/build.gradle, icon.png, and pages/index JS/HML/CSS).
  • Security & Secret Handling: Excluded local secrets from git via .gitignore and provided templates (local.properties.template, keystore.properties.template).
  • Documentation: Root and module READMEs documenting local setup, build, and sideload workflows.

Tested

  • Automated build: ./gradlew assembleDebug testDebugUnitTest (43/43 tasks passed cleanly).
  • Watch app validation: npm test passed.
  • Git secret verification: local.properties and keystore.properties confirmed ignored by git.

Summary by CodeRabbit

  • New Features
    • Introduced Watch Navigator phone and Huawei wearable applications.
    • Added destination search, travel-mode selection, navigation controls, status updates, and arrival messaging.
    • Added watch guidance with turn directions, distances, street names, and connection status.
    • Added light and dark Material 3 themes and refreshed app branding.
  • Documentation
    • Added setup, build, testing, signing, sideloading, and phone-watch messaging guidance.
  • Chores
    • Added project build configuration, credential templates, local-file protection, and validation checks.
  • Tests
    • Added coverage for navigation data validation and directional guidance.

📝 Walkthrough

Walkthrough

The change adds the Watch Navigator monorepo structure. It configures the Android phone app, creates its initial UI, and adds the Huawei Lite Wearable app with navigation display logic, build metadata, resource files, and setup documentation.

Changes

Watch Navigator foundation

Layer / File(s) Summary
Phone application build foundation
.gitignore, phone-app/*.gradle.kts, phone-app/gradle/*, phone-app/gradlew*, phone-app/*properties.template, phone-app/app/build.gradle.kts, phone-app/app/proguard-rules.pro
The phone project includes Gradle configuration, dependencies, wrapper scripts, API key handling, signing templates, and ProGuard rules.
Phone application shell
phone-app/app/src/main/AndroidManifest.xml, phone-app/app/src/main/java/..., phone-app/app/src/main/res/*, phone-app/app/src/test/*
The Android app has a launcher activity, navigation form, Material 3 theme resources, launcher icons, and unit tests.
Watch application project foundation
README.md, watch-app/README.md, watch-app/package.json, watch-app/build.gradle, watch-app/entry/build.gradle, watch-app/settings.gradle, watch-app/entry/src/main/config.json, watch-app/entry/src/main/js/default/app.js, watch-app/src/app.ts, watch-app/entry/src/main/resources/*, watch-app/tsconfig.json
The repository documents both applications. The watch project defines package metadata, build configuration, entry points, page routing, lifecycle handlers, validation scripts, TypeScript settings, and localized strings.
Watch navigation page
watch-app/entry/src/main/js/default/pages/index/*, watch-app/src/pages/index/index.ts, watch-app/src/types.ts, watch-app/test/types.test.ts
The watch page renders idle and navigation states, validates navigation packets, maps turn values to directional icons, manages Wear Engine receiver hooks, and tests the navigation contract.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 90c6f

The PR establishes the phone and watch application foundations and is mergeable with owner awareness: the documented Node.js range does not support the configured unit-test command, the future phone-to-watch navigation contract still needs authorization and message-lifecycle rules, and two README code fences need language tags for lint compliance.

message receiver in the watch page that calls updateNavigation, register it

navigation button sends the navigation payload instead of remaining a
placeholder. Align README.md lines 70-80, watch-app/README.md lines 7-10, and

needed to produce its HAP package. Replace the placeholder test script with a
command that invokes the documented DevEco build or validation flow, ensuring
the repository can reproduce a HAP build.

In `@phone-app/app/src/main/java/com/watchnavigator/MainActivity.kt`:
- Line 10: Update MainActivity’s isNavigating state handling to survive Activity
recreation by saving it in the instance state and restoring it during
initialization, or by deriving it from the active navigation session. Ensure the
UI does not incorrectly return to “Ready to navigate” while navigation remains
active.

In `@phone-app/app/src/main/res/layout/activity_main.xml`:
- Line 55: Replace the hardcoded user-visible labels in the layout, including
“Watch Connection” and “Travel Mode,” with references to newly defined string
resources; add the corresponding entries to the app’s string resources so
localized configurations can override them.
- Around line 52-66: Update the label TextView immediately preceding tvStatus to
describe navigation status rather than watch connection, while leaving tvStatus
and MainActivity.toggleNavigation() behavior unchanged.

In `@watch-app/entry/src/main/js/default/pages/index/index.js`:
- Around line 48-49: Strengthen the input validation in updateNavigation so
malformed packets are ignored before turn normalization: reject arrays, require
data.turn to be a string, and validate all remaining navigation fields against
the defined JSON contract before updating state. Preserve processing only for
fully valid packets and prevent non-string turn values from reaching
toLowerCase().

Greptile Summary

Introduces the initial Android phone and Huawei Lite Wearable monorepo skeleton, including build tooling, navigation UI scaffolding, shared navigation data types, tests, and setup documentation.

  • Configures the Android application with Kotlin, Material 3, Google location and Places dependencies, and Huawei Wear Engine.
  • Configures the watch application with DevEco resources and a TypeScript build that emits JavaScript into the packaged runtime tree.
  • Adds credential templates, generated-artifact exclusions, and local build and sideload instructions.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains; the watch TypeScript configuration now emits runtime JavaScript into the directory packaged by DevEco.

Important Files Changed

Filename Overview
phone-app/app/build.gradle.kts Configures the Android application, signing, API-key injection, Java/Kotlin targets, and runtime and test dependencies.
phone-app/app/src/main/java/com/watchnavigator/MainActivity.kt Adds the base phone navigation UI controller with start/stop state preservation.
watch-app/tsconfig.json Compiles the TypeScript source tree into the DevEco-packaged JavaScript directory, resolving the previously reported no-output configuration.
watch-app/package.json Defines watch build, type-check, lint, formatting, unit-test, and configuration-validation workflows.
watch-app/src/pages/index/index.ts Implements the typed watch navigation page state and payload-handling scaffold.
watch-app/entry/src/main/config.json Declares the Lite Wearable application module, runtime source path, device target, and page entry point.
