# AI Glasses Android App

Demo Android client for backend API validation and BLE integration scaffold.

## What is implemented

- Backend API calls:
  - `bind-confirm`
  - `create session`
  - `stop session`
  - `device status`
- Compose UI for debug flow
- Hichips BLE protocol manager:
  - service/char: `3D20(3D21/3D22/3D23)`, `5DC0(5DC1/5DC2/5DC3)`
  - packet codec: `HICH + Command + Index + Length + CRC16 + Data + IPSE`
  - handshake flow (`AG_CMD_HS_DEV_UUID` -> `AG_CMD_HS_APP_UUID` -> `AG_CMD_HS_DEV_INFO`)
  - wake-up audio uplink (`ASR_*` commands, audio from `5DC2`)
  - camera trigger (`AG_CMD_P_TAKE_START`) and thumbnail events
- New "开始对话(硬件)" button:
  - BLE scan/connect -> handshake -> backend bind/create session
  - start wake-up audio stream + periodic camera capture
  - app reports aggregated audio/camera relay stats to backend events

## Default backend
