Feature specification from `specs/20260521-153452-car-app-library-integration/spec.md` + +## Summary + +Integrate Android Car App Library 1.9.0-alpha01 into Meshtastic-Android as a new `feature/car` module, delivering a complete automotive mesh radio interface with 7 screens (messaging, node dashboard, channel management, emergency alerts, map, quick actions, mesh status panel). The module is Android-only, reuses all existing `core/` business logic via Koin DI, and leverages CAL's template-based rendering (no Compose). Voice reply uses CAL's built-in ConversationItem voice input; system-level "Hey Google" commands are handled separately by the AppFunctions feature. + +## Technical Context + +**Language/Version**: Kotlin 2.3+ targeting JDK 21, Car API Level 8+ + +**Primary Dependencies**: `androidx.car.app:app:1.9.0-alpha01`, `androidx.car.app:app-projected:1.9.0-alpha01`, `androidx.car.app:app-automotive:1.9.0-alpha01`, Koin 4.2.1 (Koin Annotations + K2 Plugin), Firebase Crashlytics (BOM 34.13.0) + +**Storage**: Room KMP (existing), DataStore KMP (existing) — no new storage + +**Testing**: `./gradlew :feature:car:testGoogleDebugUnitTest` (Android-only module), `androidx.car.app:app-testing:1.9.0-alpha01` for host simulation, Robolectric for unit tests + +**Target Platform**: Android Auto (projection, API 23+) and AAOS (embedded), Car API Level 8 minimum + +**Project Type**: Mobile app — new Android-only feature module within KMP project + +**Performance Goals**: Message display latency ≤ 3s, emergency banner ≤ 1s, channel switch ≤ 1s, map pin update ≤ 5s + +**Constraints**: ≤ 2 taps for all primary actions, < 10% battery overhead, zero crashes/ANRs in 2-hour sessions, `google` flavor only + +**Scale/Scope**: 7 car screens, ~15-20 new source files, 1 new Gradle module, 0 changes to existing modules' APIs + +## Constitution Check + +*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.* + +- **I. Kotlin Multiplatform Core**: ✅ PASS — No `commonMain` changes. All new code resides in `feature/car/src/main/` (Android-only module). Business logic is consumed from existing `core/repository`, `core/data`, `core/domain`, `core/ble` KMP modules via their public interfaces. No new business logic is introduced in the car module — it is purely a presentation layer adapting existing repositories to CAL templates. + +- **II. Zero Lint Tolerance**: ✅ PASS — Will run: + - `./gradlew :feature:car:spotlessApply :feature:car:spotlessCheck` + - `./gradlew :feature:car:detekt` + - Module is Android-only so uses standard detekt tasks (not KMP variants) + +- **III. Compose Multiplatform UI**: ✅ N/A — Car App Library uses its own template-based rendering system, not Compose. No `@Composable` functions are introduced. `MeshtasticNavDisplay` and `NavigationBackHandler` do not apply to CAL's `ScreenManager` navigation. No floats displayed (all text pre-formatted by existing `MetricFormatter`/`NumberFormatter` in core modules). + +- **IV. Privacy First**: ✅ PASS — No new data collection or network calls. Reuses existing repositories with their privacy controls. Location data on map uses existing user-opt-in position sharing. No PII/keys in logs. Crashlytics tagging uses session ID only (no PII). `core/proto` submodule not modified. + +- **V. Design Standards Compliance**: ✅ N/A (justified) — CAL apps use automotive-specific template design language enforced by the Android Auto host, not the Meshtastic Client Design Standards which target phone/desktop Compose UI. The host enforces readability (font sizes, item limits, distraction guidelines). Cross-Platform Spec field is N/A because CAL is Android-only with no cross-platform equivalent. Emergency alert visual treatment follows NHTSA Phase 2 automotive HMI guidelines via CAL Banner APIs. + +- **VI.

Older hosts gracefully hide the app. + +## R2: Module Architecture — Android-Only vs KMP + +**Decision**: Create `feature/car` as an Android-only library module (not KMP) + +**Rationale**: CAL SDK is exclusively Android. Creating a KMP module with only `androidMain` source sets would add unnecessary complexity (empty `commonMain`, unused KMP plugin overhead). The project already has Android-only modules (`core/api`, `core/barcode`, `androidApp`) as precedent. + +**Build plugin**: `AndroidLibraryFlavorsConventionPlugin` (not `KmpLibraryConventionPlugin`) — ensures proper flavor-aware configuration consistent with existing Android-only modules. + +**Alternatives considered**: +- KMP module with `androidMain` only → Rejected: No cross-platform value; KMP plugin adds 2-3s build overhead with zero benefit +- Inline within `androidApp` module → Rejected: Violates separation of concerns; feature modules should be independent + +## R3: BLE Connection Sharing Strategy + +**Decision**: Shared Application-scoped `BleConnection` singleton via Koin, no new connection management + +**Rationale**: The existing `BleConnection` in `core/ble` is already scoped to the Application lifecycle via Koin's singleton scope. When Android Auto starts the `CarAppService`, it runs in the same process as the phone app (projection mode) — the Koin graph is shared naturally. The `CarAppService` keeps the process alive via the Android Auto host binding, ensuring the BLE connection persists. + +**Key implementation detail**: `KableBleConnection` is instantiated by `KableBleConnectionFactory` and held as a Koin singleton. The car module simply injects the same instance — no reconnection logic needed. + +**AAOS (embedded) consideration**: On AAOS, the app runs as a standalone process. The same Koin graph initializes in `Application.onCreate()`. BLE connection management is identical because it's Application-scoped regardless of entry point. + +**Alternatives considered**: +- Dedicated car BLE connection → Rejected: Would conflict with phone app's connection; BLE to Meshtastic radio is single-link +- Service binding to phone app → Rejected: Unnecessary IPC; same process in projection mode; AAOS doesn't have the phone app + +## R4: Crashlytics car_session Tagging + +**Decision**: Tag all Crashlytics events with `car_session` custom key during car session lifecycle + +**Rationale**: Enables filtering car-specific crashes/ANRs in Firebase console without new infrastructure.

It handles: +- Message display with sender avatar, name, timestamp +- Unread indicators +- Voice reply flow (tap → record → send) with no custom speech recognition needed +- Quick-reply suggestions + +The existing `SendMessageUseCase` in `core/repository` accepts `(text, contactKey, replyId)` — the car module calls this directly after voice transcription completes. + +**Data flow**: `ConversationItem.onReply { text -> sendMessageUseCase(text, contactKey) }` + +**Alternatives considered**: +- Custom speech recognition → Rejected: CAL handles this automatically; would duplicate system capabilities +- Google Assistant App Actions → Rejected: Separate concern handled by AppFunctions feature + +## R6: PlaceListMapTemplate for Node Map (POI Category) + +**Decision**: Use `PlaceListMapTemplate` under POI category for static node position display + +**Rationale**: POI category avoids NAVIGATION category requirements (turn-by-turn guidance, active routing), which would trigger additional Play Store review burden and potential conflicts with navigation apps. `PlaceListMapTemplate` renders a map with place items (pins) + a scrollable list — perfect for showing node positions. + +**Implementation approach**: +- Each node with known GPS position becomes a `Place` item with `LatLng` +- List items show node name + distance + last update time +- Map auto-zooms to fit all visible pins +- Tap a list item → NodeDetailScreen with message option +- Refresh interval: 5 seconds (matches NFR map update latency requirement) + +**Limitation**: No live tracking line or animated position updates (NAVIGATION category feature, deferred to v2) + +**Alternatives considered**: +- MapWithContentTemplate + NAVIGATION category → Rejected by spec decision; deferred to v2 +- No map at all → Rejected: Location awareness is core Meshtastic differentiator + +## R7: Koin DI Integration for Car Module + +**Decision**: New `FeatureCarModule` using Koin Annotations, registered in app's module graph + +**Rationale**: Consistent with project's DI pattern. All feature modules declare a Koin module that is included by the `androidApp` module graph. The car module's DI graph is simple — it only needs to declare car-specific Screen factories and the EmergencyHandler; all business logic comes from existing core modules. + +**Registration**: `androidApp/src/googleMain/` includes `FeatureCarModule` in the Koin application configuration (google flavor only). + +**Key bindings**: +- `MeshtasticCarSession` → factory (new per session) +- `EmergencyHandler` → singleton (one per process) +- `CrashlyticsCarTagger` → singleton +- All repositories, use cases → inherited from existing core modules (already in graph) + +## R8: AppFunctions Interop — Shared Interface Reuse + +**Decision**: Reuse `FuzzyNameResolver` pattern from AppFunctions for node name matching in voice replies + +**Rationale**: When a driver sends a direct message via voice, they may say a node name imprecisely. The AppFunctions feature (in-flight) implements fuzzy node name resolution. While the `AiFunctionProvider` interface is not yet merged, the car module can implement the same fuzzy matching logic directly using `NodeRepository.nodeDBbyNum` and Levenshtein distance or substring matching. + +**Implementation**: Standalone `FuzzyNodeNameResolver` utility class in `feature/car/util/` that queries `NodeRepository` and performs case-insensitive substring + edit-distance matching. If/when AppFunctions lands and exposes a shared resolver in `core/data/commonMain`, the car module can delegate to it. + +**Alternatives considered**: +- Wait for AppFunctions to land first → Rejected: Unclear timeline; car module should not block on it +- Exact match only → Rejected: Poor voice UX ("node exclamation one two three four" vs "James") + +## R9: Emergency Alert Banner Strategy + +**Decision**: Observe emergency messages via `PacketRepository` Flow, trigger CAL Banner API + +**Rationale**: Emergency messages are already classified in the packet data layer (message type/priority). The `EmergencyHandler` subscribes to the message flow, filters for emergency-priority packets, and immediately invokes `CarToast` + `AppManager.showAlert()` to display a Banner. The Banner overlays any active screen within CAL's rendering pipeline. + +**Audio**: Use `NotificationManager` to play a notification sound on the car's notification audio channel (`AudioAttributes.USAGE_NOTIFICATION`), not media channel (per NFR-008). + +**Alternatives considered**: +- Poll for emergencies on timer → Rejected: Violates 1-second latency requirement +- Use Android notifications only → Rejected: Would not overlay within CAL UI; needs in-app Banner + +## R10: Build Configuration — Google Flavor Only + +**Decision**: `feature/car` module included only in the `google` product flavor + +**Rationale**: CAL apps require Google Play Services for Android Auto projection.

CarAppService keeps the process alive via Android Auto host; BLE connection persists at the Service/Application level, not Activity level. +- Q: What observability approach should the car module use? → A: Reuse existing Crashlytics with `car_session` custom key tagging for car-specific filtering. No new observability infrastructure; tag existing analytics paths. +- Q: Should the car app unlock additional features when the vehicle is parked? → A: No parked-mode differentiation. Templated messaging apps provide a uniform experience regardless of driving state. Voice reply is built into ConversationItem. The Android Auto host enforces its own driving restrictions; the app just provides templates. + +## Goals + +1. **Complete automotive mesh experience** — Deliver all seven core screens (messaging, node dashboard, channel management, emergency alerts, map, quick actions, mesh status panel) as a single release +2. **Safety-first interaction model** — Every interaction completes in ≤ 2 taps or via voice, meeting automotive distraction guidelines +3. **Leverage 1.9.0-alpha01 components** — Showcase Spotlight Sections, Condensed Items, Chips, Minimized Control Panel, Banners, Section Headers, and Expanded Headers for a modern car UI +4. **Zero disruption to existing app** — The new `feature/car` module integrates via dependency injection without modifying existing module APIs or behavior +5. **Voice-first messaging** — Message composition defaults to voice input, with quick-reply templates as fallback for hands-free operation + +## Non-Goals + +- Firmware updates via the car interface (too complex and risky while driving) +- Full settings UI in-car (a minimal parked-only subset may be considered in future) +- Desktop or iOS car support (this is Android Auto / AAOS specific) +- Video playback or media/audio streaming features +- Compose UI interop (CAL uses its own template-based rendering system) +- Google Assistant App Actions / voice command routing (handled by separate AppFunctions feature) +- NAVIGATION category declaration / live map tracking (deferred to v2; v1 uses POI with PlaceListMapTemplate) +- Phone app UI changes (car UI is additive only) + +## User Scenarios & Testing *(mandatory)* + +### User Story 1 - Read and Reply to Mesh Messages While Driving (Priority: P1) + +A driver receives mesh messages from their group while on the road. They glance at the head unit to see new messages and use voice to compose a reply, keeping hands on the wheel and eyes on the road. + +**Why this priority**: Messaging is the primary use case for Meshtastic. Enabling safe in-car messaging addresses the #1 reason users would want car integration. + +**Independent Test**: Can be fully tested by sending a message from a second Meshtastic device, verifying it appears on the car display, and dictating a voice reply that arrives on the sender's device. + +**Acceptance Scenarios**: + +1. **Given** the car app is connected to a Meshtastic radio and a new message arrives, **When** the driver views the messaging screen, **Then** the new message appears within 3 seconds with sender name, timestamp, and message content visible at a glance +2. **Given** the driver is viewing a conversation, **When** they tap the reply action, **Then** the system presents voice input as the default composition method +3. **Given** the driver has initiated voice reply, **When** they speak their message and confirm, **Then** the message is sent to the correct channel/DM within 2 seconds +4. **Given** the driver prefers not to use voice, **When** they select quick-reply, **Then** a list of configurable template responses (e.g., "On my way", "Copy that", "10 minutes out") is presented for one-tap selection +5. **Given** the mesh radio is disconnected, **When** the driver opens messaging, **Then** a banner clearly indicates offline status and cached messages remain visible as read-only + +--- + +### User Story 2 - Emergency Alert Reception (Priority: P1) + +A driver receives an emergency alert broadcast from a mesh node (SOS, hazard warning, etc.). The alert demands immediate attention with distinct visual and audio treatment, regardless of which screen is currently active. + +**Why this priority**: Emergency alerts are life-safety critical. Failure to surface them prominently could have real-world safety consequences. + +**Independent Test**: Can be tested by triggering an emergency broadcast from a test device and verifying the car app interrupts current activity with a banner alert. + +**Acceptance Scenarios**: + +1. **Given** any screen is active, **When** an emergency message is received, **Then** a high-priority banner appears immediately (within 1 second) with emergency iconography and distinct color treatment +2. **Given** an emergency banner is displayed, **When** the driver taps it, **Then** full emergency details are shown including sender identity, location (if available), and timestamp +3. **Given** an emergency alert has been received, **When** the driver navigates to the messaging screen, **Then** the emergency message appears in a Spotlight Section at the top, visually distinguished from normal messages +4. **Given** emergency audio alerts are enabled, **When** an emergency message arrives, **Then** an audible notification tone plays through the car's audio system + +--- + +### User Story 3 - Monitor Node Network Status (Priority: P2) + +A driver glances at the head unit to check how many mesh nodes are in range, their signal strength, and battery levels — useful for caravan/convoy scenarios or checking if they're still in range of base camp. + +**Why this priority**: Node awareness is the second-most-common Meshtastic use case and provides critical situational awareness for mobile users. + +**Independent Test**: Can be tested by having 3+ nodes in range and verifying the dashboard displays each with correct signal/battery metrics. + +**Acceptance Scenarios**: + +1. **Given** the car app is connected with multiple nodes in range, **When** the driver opens the node dashboard, **Then** all known nodes are displayed as Condensed Items showing node name, signal quality indicator, and battery level +2. **Given** 6+ nodes are in range, **When** viewing the dashboard, **Then** at least 6 nodes are visible simultaneously without scrolling (leveraging Condensed Items) +3. **Given** a node goes offline, **When** the dashboard refreshes, **Then** the offline node is visually distinguished (dimmed or marked) and sorted to the bottom +4. **Given** the node list is displayed, **When** the driver taps a node, **Then** a detail view shows last heard time, distance (if location known), hardware model, and direct message option + +--- + +### User Story 4 - Switch Between Channels (Priority: P2) + +A driver participating in multiple mesh channels (e.g., "Convoy", "Emergency", "General") quickly switches between them to view messages from different groups. + +**Why this priority**: Channel management is essential for users in organized groups and must be achievable without complex navigation. + +**Independent Test**: Can be tested by configuring 3+ channels and verifying single-tap channel switching via chips. + +**Acceptance Scenarios**: + +1. **Given** the device has multiple channels configured, **When** the messaging screen loads, **Then** channel chips are displayed at the top allowing single-tap switching +2. **Given** channel chips are visible, **When** the driver taps a different channel chip, **Then** the message list updates to show that channel's messages within 1 second +3. **Given** a channel has unread messages, **When** viewing the chip bar, **Then** that channel's chip displays an unread indicator (badge or visual emphasis) + +--- + +### User Story 5 - View Node Locations on Map (Priority: P2) + +A driver in a convoy scenario views the locations of all mesh nodes on a map to understand relative positions and navigate toward or away from group members. + +**Why this priority**: Location awareness is a core differentiator of Meshtastic and maps are natural for automotive interfaces. + +**Independent Test**: Can be tested by having 2+ nodes reporting GPS positions and verifying pins appear at correct locations on the car map. + +**Acceptance Scenarios**: + +1. **Given** nodes are reporting GPS positions, **When** the driver opens the map screen, **Then** node locations appear as labeled items in a PlaceListMapTemplate with pins on the map +2. **Given** the map is displayed with node pins, **When** the driver taps a node item in the list, **Then** a detail panel shows node name, distance, last update time, and option to send a direct message +3. **Given** the driver's own position is available, **When** viewing the map, **Then** their position is shown distinctly from other nodes +4. **Given** a node's position updates, **When** the map is visible, **Then** the pin moves to the new position within 5 seconds + +--- + +### User Story 6 - Persistent Mesh Status at a Glance (Priority: P3) + +While using any car app feature, the driver can glance at a persistent mini-panel showing mesh connectivity health — how many nodes are online, time since last message, and connection status to the radio. + +**Why this priority**: Persistent status awareness reduces the need to navigate between screens, minimizing distraction. + +**Independent Test**: Can be tested by verifying the minimized control panel remains visible across all screens and updates in real-time. + +**Acceptance Scenarios**: + +1. **Given** the car app is active on any screen, **When** the driver glances at the minimized control panel, **Then** they see: radio connection status, node count online, and time since last received message +2. **Given** the radio disconnects, **When** the status panel updates, **Then** it clearly indicates "Disconnected" with warning iconography +3. **Given** the minimized panel is visible, **When** the driver taps it, **Then** it expands to show additional detail (mesh name, own node battery, firmware version) + +--- + +### User Story 7 - In-Context Voice Input for Actions (Priority: P3) + +A driver uses CAL's built-in voice input to compose messages and perform actions without typing — tapping reply then dictating, or using TTS readback of messages. System-level voice commands ("Hey Google, send Meshtastic message to John") are handled separately by the AppFunctions feature and work automatically on car displays without car module code. + +**Why this priority**: Voice is the safest interaction modality while driving and rounds out the hands-free experience. + +**Independent Test**: Can be tested by tapping the reply action, dictating a message via CAL voice input, and verifying delivery. System-level "Hey Google" commands are tested via the AppFunctions spec. + +**Acceptance Scenarios**: + +1. **Given** the car app is on a conversation screen, **When** the driver taps the reply action and speaks a message, **Then** voice composition targets that node/channel using CAL's built-in voice input API +2. **Given** a message is displayed, **When** the driver taps a "read aloud" action, **Then** the message is read via TTS including sender name and content +3. **Given** the driver initiates a direct message from the node dashboard, **When** they tap a node and select "message", **Then** voice input is presented as the default composition method with `FuzzyNameResolver` used for node name matching + +--- + +### Edge Cases + +- What happens when the Bluetooth connection to the Meshtastic radio drops mid-conversation? → Banner notification + graceful degradation to cached data, auto-reconnect in background +- What happens when the message list exceeds CAL template item limits? → Cap at 10 conversations with 5 messages each per Android Auto best practices; most recent first +- How does the system handle very long messages that exceed car display constraints? → Truncation with "..." and full message available on tap or read-aloud +- What happens when outgoing messages exceed 237 bytes (Meshtastic protocol limit)? → Reject with user feedback ("Message too long"); do not attempt to send +- What happens when the car's system restricts interaction (e.g., car moving at speed)? → No parked-mode differentiation; the templated messaging UI is uniform regardless of driving state. Voice reply is built into ConversationItem automatically. The Android Auto host enforces its own driving restrictions — the app provides templates only. +- What happens when multiple emergency alerts arrive simultaneously? → Stack as multiple banners; Spotlight Section shows all active emergencies chronologically +- How does the app handle no configured channels? → Show onboarding prompt directing user to configure channels on their phone first +- What happens with emoji-only or admin messages? → Filtered from car display entirely (not shown in conversation list or read aloud) +- What happens on initial session connect with existing unread messages? → Batch-load up to 50 unread messages across conversations; also post MessagingStyle notifications for read-back support +- How are favorites vs recent contacts distinguished? → Favorites

+ +## Source-Set Impact + +| Source Set | Impact | Justification | +|-----------|--------|---------------| +| `commonMain` | No changes | All shared business logic already exists in core modules | +| `androidMain` | New `feature/car` module | CAL is Android-only; entire car UI layer is platform-specific | + +## Design Standards Compliance + +- [ ] New screens reviewed against automotive HMI distraction guidelines (NHTSA Phase 2) +- [ ] CAL template system used exclusively (no custom rendering that bypasses automotive safety checks) +- [ ] Accessibility: Voice readback of all visual information, high-contrast automotive color schemes +- [ ] Typography: Uses CAL's built-in automotive-safe text sizing (enforced by host) +- [ ] Emergency alerts use distinct visual language (color, iconography) distinguishable from informational banners + +## Privacy Assessment + +- [ ] No PII, location data, or cryptographic keys logged or exposed beyond what existing modules already handle +- [ ] Car app reuses existing data layer — no new network calls or data collection +- [ ] Node location data displayed on map uses existing privacy controls (user opt-in for position sharing) +- [ ] No data sent to third-party automotive services +- [ ] Proto submodule (`core/proto`) not modified (read-only upstream) + +## Success Criteria *(mandatory)* + +### Measurable Outcomes + +- **SC-001**: Users can read a new message and send a voice reply in under 15 seconds total interaction time +- **SC-002**: Emergency alerts are visible to the driver within 1 second of receipt by the radio +- **SC-003**: Node dashboard displays 6+ nodes simultaneously without scrolling (Condensed Items density) +- **SC-004**: All primary actions (read message, reply, check nodes, view map) reachable within 2 taps from home +- **SC-005**: Car app adds < 10% battery drain overhead compared to phone-only operation over a 1-hour driving session +- **SC-006**: Channel switching completes (chip tap to new message list rendered) within 1 second +- **SC-007**: App passes Android Auto App Quality review criteria for the MESSAGING category +- **SC-008**: 95% of voice-initiated replies complete successfully without fallback to touch input +- **SC-009**: Map displays node positions with < 5-second update latency when positions change +- **SC-010**: Zero crashes or ANRs attributed to the car module during a 2-hour continuous driving session + +## Assumptions + +- Car App Library 1.9.0-alpha01 APIs are sufficiently stable for production use (alpha risk accepted per user directive) +- The existing `core/data` repositories provide all necessary data access; no new data sources required +- Meshtastic radio remains paired and connected via BLE during driving (standard operating mode) +- BLE connection is Application-scoped (not Activity-scoped); CarAppService keeps the host process alive so the connection naturally persists regardless of phone app Activity state +- Users have already configured channels and node settings via the phone app before driving +- Android Auto host enforces its own distraction-optimization rules (template item limits, interaction restrictions); the app respects these constraints +- The `google` build flavor is the distribution target; F-Droid/GitHub flavors do not include car support +- Quick-reply templates are configurable via the phone app's settings; the car app consumes them read-only +- Voice input quality depends on the car's microphone hardware; the app delegates to Android's speech recognition system +- MapWithContentTemplate availability depends on NAVIGATION category declaration (deferred to v2); v1 uses PlaceListMapTemplate under POI which is widely supported +- Minimum Car API Level 8 is required; older Android Auto hosts will not show the app (graceful absence, not crash) +- Koin dependency injection is used consistently with Koin Annotations for the new module +- TTS (text-to-speech) for reading messages aloud uses Android's built-in TTS engine + +## External References & Research + +### Official Documentation + +| Resource | URL | Relevance | +|----------|-----|-----------| +| Car App Library Release Notes

Setup: - Version catalog entries (car-app 1.9.0-alpha01) - Module build.gradle.kts with android-library, flavors, koin - AndroidManifest with MESSAGING category, minCarApiLevel 8 - AAOS automotive_app_desc.xml - Car-specific string resources - ProGuard keep rules Phase 2 - Foundation: - MeshtasticCarAppService (CarAppService entry point) - MeshtasticCarSession (session lifecycle, Crashlytics tagging) - FeatureCarModule (Koin DI with ComponentScan) - HomeScreen (TabTemplate: Messages + Nodes) - CrashlyticsCarTagger, TemplateBuilders helpers - CarUiModels (presentation state models) Phase 3 - Messaging (MVP): - MessagingScreen (300ms debounced invalidation, max 10 conversations) - ConversationScreen (voice reply, read-aloud, max 5 messages) - FuzzyNodeNameResolver (LCS-based voice name matching) - MessageFilter (emoji/admin exclusion, 237-byte limit) - BatchMessageLoader (50 unread on session start) - CarNotificationManager (MessagingStyle + reply/mark-read) Phase 4 - Emergency: - EmergencyHandler (flow collection, alert state, audio tone) - EmergencySpotlightBuilder (alert rows for messaging screen) - EmergencySessionWiring (lifecycle attach/detach) Phase 5 - Nodes: - NodeDashboardScreen (sorted list, signal/battery, topology header) - NodeDetailScreen (PaneTemplate with Message action) Phase 6 - Channels: - ChannelChipBuilder (ActionStrip with unread badges) Phase 8 - Status Panel: - MeshStatusPanel (connection, node count, last msg time) - MeshStatusSessionWiring (Flow-based lifecycle) Phase 9 - Voice: - CarTtsEngine (TTS read-aloud) - VoiceDmCoordinator (fuzzy resolve + voice DM flow) Phase 10 - Polish: - OnboardingScreen (no channels configured state) - DisconnectedScreen (BLE disconnect graceful degradation) -

Migrate to SendMessageUseCase (replaces raw commandSender.sendData()) - Migrate Messages tab to ConversationItem API (official required pattern) - Add ConversationCallback for native reply + mark-as-read - Add Status tab with device metrics (battery, utilization, uptime, TX/RX) - Add ConversationShortcutManager + PersonIconFactory for notification linking - Add CarScreenDataBuilder with pure testable functions (533-line test suite) - Fix notification actions (SEMANTIC_ACTION_REPLY/MARK_AS_READ, setShowsUserInterface) - Wire CarReplyReceiver to actually send messages and clear unreads - Lower minCarApiLevel from 8 to 7 with graceful API 8 fallbacks - Add android:permission on CarAppService for security - Remove dead code: ConversationScreen, CarTtsEngine, messagesCache Files added: ConversationShortcutManager, PersonIconFactory, CarScreenDataBuilder, ic_car_status.xml, CarScreenDataBuilderTest (533 lines) Files removed: ConversationScreen.kt, CarTtsEngine.kt Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- feature/car/src/main/AndroidManifest.xml | 5 +- .../feature/car/model/CarUiModels.kt | 12 + .../feature/car/screens/ConversationScreen.kt | 128 ---- .../feature/car/screens/HomeScreen.kt | 150 ++++- .../car/service/CarNotificationManager.kt | 11 +- .../feature/car/service/CarReplyReceiver.kt | 26 +- .../car/service/CarStateCoordinator.kt | 124 +--- .../service/ConversationShortcutManager.kt | 186 ++++++ .../car/service/MeshtasticCarSession.kt | 9 + .../feature/car/util/CarScreenDataBuilder.kt | 127 ++++ .../feature/car/util/CarTtsEngine.kt | 63 -- .../feature/car/util/PersonIconFactory.kt | 57 ++ .../src/main/res/drawable/ic_car_status.xml | 10 + feature/car/src/main/res/values/strings.xml | 11 +- .../car/util/CarScreenDataBuilderTest.kt | 547 ++++++++++++++++++ 15 files changed, 1145 insertions(+), 321 deletions(-) delete mode 100644 feature/car/src/main/kotlin/org/meshtastic/feature/car/screens/ConversationScreen.kt create mode 100644 feature/car/src/main/kotlin/org/meshtastic/feature/car/service/ConversationShortcutManager.kt create mode 100644 feature/car/src/main/kotlin/org/meshtastic/feature/car/util/CarScreenDataBuilder.kt delete mode 100644 feature/car/src/main/kotlin/org/meshtastic/feature/car/util/CarTtsEngine.kt create mode 100644 feature/car/src/main/kotlin/org/meshtastic/feature/car/util/PersonIconFactory.kt create mode 100644 feature/car/src/main/res/drawable/ic_car_status.xml create mode 100644 feature/car/src/test/kotlin/org/meshtastic/feature/car/util/CarScreenDataBuilderTest.kt diff --git a/feature/car/src/main/AndroidManifest.xml b/feature/car/src/main/AndroidManifest.xml index 5741e84a53..c0706eac9d 100644 --- a/feature/car/src/main/AndroidManifest.xml +++ b/feature/car/src/main/AndroidManifest.xml @@ -4,7 +4,8 @@ + android:exported="true" + android:permission="androidx.car.app.CarAppService"> @@ -17,6 +18,6 @@ + android:value="7" /> diff --git a/feature/car/src/main/kotlin/org/meshtastic/feature/car/model/CarUiModels.kt b/feature/car/src/main/kotlin/org/meshtastic/feature/car/model/CarUiModels.kt index 01721991ba..95668e0fdd 100644 --- a/feature/car/src/main/kotlin/org/meshtastic/feature/car/model/CarUiModels.kt +++ b/feature/car/src/main/kotlin/org/meshtastic/feature/car/model/CarUiModels.kt @@ -74,3 +74,15 @@ data class EmergencyAlert( val timestamp: Long, val isActive: Boolean, ) + +data class CarLocalStats( + val batteryLevel: Int = 0, + val hasBattery: Boolean = false, + val channelUtilization: Float = 0f, + val airUtilization: Float = 0f, + val totalNodes: Int = 0, + val onlineNodes: Int = 0, + val uptimeSeconds: Int = 0, + val numPacketsTx: Int = 0, + val numPacketsRx: Int = 0, +) diff --git a/feature/car/src/main/kotlin/org/meshtastic/feature/car/screens/ConversationScreen.kt b/feature/car/src/main/kotlin/org/meshtastic/feature/car/screens/ConversationScreen.kt deleted file mode 100644 index 392117989f..0000000000 --- a/feature/car/src/main/kotlin/org/meshtastic/feature/car/screens/ConversationScreen.kt +++ /dev/null @@ -1,128 +0,0 @@ -/* -

`DatabaseManagerWithDbRetryTest` to remove CI race conditions by running the manager on a `StandardTestDispatcher(testScheduler)` instead of real `Dispatchers.IO`. -- Added a `withTimeout(10_000)` guard around the test body to fail fast on coordination stalls instead of hanging/flapping. -- Kept the deterministic retry trigger (`error("Connection pool is closed")`) and retained assertions that

:feature:car:compileFdroidDebugKotlin --quiet 2>&1 | tail -30`. + +## 2026-05-28 — Migrated car home messages tab to ConversationItem +- Reworked `feature/car` `HomeScreen` messaging tab to build CAL `ConversationItem` entries instead of browsable `Row`s, including `Person`/`CarMessage` helpers and native reply/mark-read callbacks. +- Removed `HomeScreen` conversation navigation so the car host owns messaging affordances; `ConversationScreen` remains on disk for later cleanup phases. +- Added `CarStateCoordinator.markAsRead()` using `packetRepository.clearUnreadCount(...)` with Kermit error logging via `runCatching`. +- Verified with `./gradlew :feature:car:spotlessApply :feature:car:spotlessCheck :feature:car:detekt :feature:car:compileFdroidDebugKotlin` and the requested quiet compile command (`:feature:car:compileFdroidDebugKotlin --quiet 2>&1 | tail -20`), both successful. + +## 2026-05-28 — Implemented car conversation shortcuts and avatars +- Added `feature/car/.../util/PersonIconFactory.kt` to render circular initial avatars using node-derived foreground/background colors for `Person` and shortcut icons. +- Added `feature/car/.../service/ConversationShortcutManager.kt` to publish long-lived dynamic conversation shortcuts for favorite nodes and active channels, plus on-demand shortcut creation for notifications. +- Wired `MeshtasticCarSession` to start/stop shortcut observation on a dedicated session coroutine scope. +- Updated `CarNotificationManager` to ensure conversation shortcuts exist before posting and to attach both `shortcutId` and `LocusIdCompat` to messaging notifications. +- Verified green with `./gradlew :feature:car:spotlessCheck :feature:car:detekt --quiet` and `./gradlew :feature:car:compileFdroidDebugKotlin --quiet 2>&1 | tail -20` after workspace bootstrap. + +## 2026-05-28 — Implemented car local stats tab and extracted screen data builder +- Added `CarLocalStats` to `feature/car` UI models and exposed `localStatsState` from `CarStateCoordinator`. +- Wired a new HomeScreen `Status` tab with battery, channel utilization, air utilization, node counts, uptime, and packet TX/RX rows. +- Created `feature/car/.../util/CarScreenDataBuilder.kt` to centralize pure UI-model mapping helpers for nodes, conversations, local stats, uptime formatting, contact key building, and recent message selection. +- Added the new `ic_car_status.xml` drawable plus status strings in `feature/car/src/main/res/values/strings.xml`. +- Cleaned up `CarReplyReceiver` detekt violations that blocked module validation. +- Ran `python3 scripts/sort-strings.py` and verified green with `./gradlew :feature:car:spotlessApply :feature:car:spotlessCheck :feature:car:detekt :feature:car:compileFdroidDebugKotlin :feature:car:testFdroidDebugUnitTest`. + +## 2026-05-28 — Implemented car module Phase 1 messaging wiring fixes +- Replaced `CommandSender` usage in `feature/car` `CarStateCoordinator` with injected `SendMessageUseCase`, keeping the public `sendMessage()` API synchronous for UI callbacks while launching the use case on the coordinator scope after message-length validation. +- Updated `CarNotificationManager` reply and mark-read notification actions with semantic action metadata and `setShowsUserInterface(false)` for automotive-friendly inline handling. +- Reworked `CarReplyReceiver` into a `KoinComponent` that injects `SendMessageUseCase` and `PacketRepository`, then sends replies / clears unread counts asynchronously with Kermit error logging. +- Added `android:permission="androidx.car.app.CarAppService"` to the `MeshtasticCarAppService` manifest declaration. +- Verified with `./gradlew :feature:car:compileFdroidDebugKotlin --quiet` after required workspace bootstrap. ## 2026-05-21 — Upgraded Chirpy to a fully-personalized Live Diagnostic Node & Mesh Assistant - Integrated `NodeRepository` into `GeminiNanoDocAssistant.kt` and the Google AI Koin dependency injection module (`GoogleAiModule.kt`). diff --git a/feature/car/src/main/kotlin/org/meshtastic/feature/car/panels/MeshStatusPanel.kt
