James Rich 805f9a3cd2 fix(serial): refresh USB device list on Android 12+ attach and resume 
Android 12+ delivers ACTION_USB_DEVICE_ATTACHED only to manifest-declared
receivers; the runtime-registered UsbBroadcastReceiver inside UsbRepository
never sees this event. Forward it explicitly from MainActivity so the
serialDevices StateFlow refreshes and the device appears in the Connect →
Serial tab without requiring the user to replug.

Also re-poll in onResume() to handle process-restart or returning from
another app while a USB device was already attached.

: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.
