## Symptom
A factory/office Android TV has no browser, the 7-tap developer-options menu is removed by the manufacturer, and the app store has nothing useful. Goal: show a web dashboard full-screen.

## Fix
1. From a laptop on the same network, first check whether the TV already has network adb enabled — many vendor TVs ship with it on and no authorization prompt:
```bash
adb connect <tv-ip>:5555
adb install kiosk.apk
```
2. If adb is closed: install a Chinese TV app market's assistant that offers LAN file transfer (e.g. Dangbei Assistant's "file transfer" page served at `http://<tv-ip>:4343`), then push the APK from the laptop: `curl -F "file1=@browser.apk;type=application/vnd.android.package-archive" http://<tv-ip>:4343/upload` and confirm Install on the TV.
3. A minimal kiosk APK (full-screen WebView, keep-screen-on, periodic reload, retry on error, `BOOT_COMPLETED` autostart) is more reliable than a TV browser.

## Verify
Dashboard shows full-screen and survives a TV reboot.

## Notes
- Android 4.4 lacks modern root CAs, so HTTPS sites with newer chains fail in WebView; a kiosk app pointed at your own known URL may need to handle that (or serve the page over a chain old devices trust).
- Prefer a static page with `<meta http-equiv="refresh" content="30">` over a heavy SPA on old TV WebViews.
