James Rich e9cb439849 feat: rearchitect around SDK — decompose RadioController, simplify DataPacket, integrate SDK utilities
Android rearchitecture consuming meshtastic-sdk improvements:

A1 — ConnectionState Enrichment:
- Rich sealed interface with Connecting(attempt), Configuring(phase, progress), Reconnecting(attempt)
- SdkStateBridge maps SDK states preserving metadata

A2 — MessageHandle Integration:
- MessageDeliveryTracker: tracks delivery via SDK MessageHandle
- SdkRadioController captures handles on send

A3 — RadioController Decomposition:
- Split into 5 focused interfaces: MessageSender, DeviceAdmin, RemoteAdmin, DeviceControl, DataRequester
- RadioController extends all; SdkRadioController binds all via Koin

A4 — DataPacket Simplification:
- to/from fields changed from String? to Int (node numbers directly)
- Removed string ID parsing layer; added BROADCAST/LOCAL constants
- Updated ~40 consumer files across feature modules

A5 — SDK Utility Consumption:
- DeviceVersion, Capabilities, SfppHasher, LocationUtils delegate to SDK
- Removed duplicated protocol logic

A6 — Presence Events:
- SdkStateBridge handles NodeChange.WentOffline/CameOnline
- Updates node online status via repository

: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.
