# Android background capture (Scenario 2)

Unlike iOS, Android **allows background message capture**, so you get real on-phone autonomy — just
not for iMessage. A no-build recipe (Tasker or MacroDroid) calls the same shared **`POST /agent`**
backend the Mac collector and iOS Shortcut use.

## What you need
- The backend reachable from the phone: the HF Space's dedicated-GPU path, a Mac/cloud box, or even
  the phone itself (Termux). The free **ZeroGPU Space does not serve `/agent`** (Gradio-SDK only) — use
  one of the others.
- The same `INGEST_TOKEN` the backend uses.

## Tasker recipe (Notification Access — works for RCS/WhatsApp/SMS notifications)
1. **Profile → Event → UI → Notification** (or **Phone → Received Text** for SMS). Restrict it to
   your messaging app(s).
2. **Task → Net → HTTP Request:**
   - Method: `POST`
   - URL: `https://<your-backend>/agent`
   - Headers: `Authorization: Bearer <INGEST_TOKEN>` and `Content-Type: application/json`
   - Body:
     ```json
     { "thread": "%evtprm()", "now": "%TIMES", "push_gcal": true }
     ```
     (Use the notification text variable your trigger provides for `thread`; `%TIMES` → current time.)
3. **Parse the response** (`Variable → JSON Read` on `plan.events`) if you want a confirmation
   toast/notification; otherwise `push_gcal:true` already created the events in Google Calendar.

MacroDroid is equivalent: **Trigger:** Notification Received / SMS Received → **Action:** HTTP POST
with the same URL/headers/body.

## Notes
- This is genuinely hands-off: the OS delivers the trigger in the background.
- For a fully on-device variant, run the backend + a small model in **Termux** and point Tasker at
  `http://127.0.0.1:7860/agent`, with `INFERENCE_BASE_URL` → a local `llama-server` (Gemma E4B / a
  small Hermes). See [on-device.md](./on-device.md) and [hermes.md](./hermes.md).
- A native Kotlin `NotificationListenerService` app could replace Tasker for a polished install — a
  separate effort; the Tasker recipe is the MVP.
