James Rich 0df6d70317 refactor(auto): extract Android Auto into feature:auto module
- Move MeshtasticCarAppService, CarSession, CarScreen from app/auto
  to the new :feature:auto module (meshtastic.android.library)
- Move automotive_app_desc.xml → auto_app_desc.xml (respects resourcePrefix)
- Move manifest entries (service + meta-data) into feature module so they
  merge into app rather than living in the app manifest directly
- Fix HostValidator: use ApplicationInfo.FLAG_DEBUGGABLE instead of
  BuildConfig.DEBUG (library modules don't ship their own BuildConfig)
- Fix stale unread counts: replace point-in-time getUnreadCount() with
  flatMapLatest + per-conversation getUnreadCountFlow() so the car screen
  invalidates on new messages, not just topology changes
- Fix ConversationShortcutManager: replace removeAllDynamicShortcuts +
  addDynamicShortcuts with pushDynamicShortcut per conversation to
  preserve usage/ranking history; remove stale shortcuts individually;
  respect getMaxShortcutCountPerActivity() limit
- Fix SHORTCUT_CATEGORY_CONVERSATION: constant lives on ShortcutInfo,
  not ShortcutManagerCompat
- Remove androidx.car.app dependency from :app (now owned by :feature:auto)
- Add :feature:auto to settings.gradle.kts and app dependencies

:app

Overview

The :app module is the entry point for the Meshtastic Android application. It orchestrates the various feature modules, manages global state, and provides the main UI shell.

Key Components

1. MainActivity & Main.kt

The single Activity of the application. It hosts the shared MeshtasticNavDisplay navigation shell and manages the root UI structure (Navigation Bar, Rail, etc.).

2. MeshService

The core background service that manages long-running communication with the mesh radio. While it is declared in the :app manifest for system visibility, its implementation resides in the :core:service module. It runs as a Foreground Service to ensure reliable communication even when the app is in the background.

3. Koin Application

MeshUtilApplication is the Koin entry point, providing the global dependency injection container.

Architecture

The module primarily serves as a "glue" layer, connecting:

  • core:* modules for shared logic.
  • feature:* modules for specific user-facing screens.
