Argent TV (Apple TV + Android TV + Fire TV)
Critical
- A TV is focus-driven, not touch-driven. Drive every interaction with
describe+tv-remote+keyboard; never usegesture-*/ coordinate taps — they don't apply on any TV platform. - Always
describebefore navigating to find the live cursor and your target — never guess focus from a screenshot. The cursor is the focused element; on Vega the toolkit often leavesfocusedfalse and marks the highlighted item[selected], so treat[selected]as the cursor when nothing reports[focused]. - Pass the
udidfromlist-devices— an Apple TV simulator UDID or an Android TV / Vegaserial. Dispatch is automatic from the id; the same tools drive all three.
The navigation loop
describe— find the cursor and your target (returns the focused element + all focusable ones, not a tap tree).tv-remote— move focus toward the target. Prefer one call with a path ending inselect, e.g.{button:["down","right","select"]}; count rows/columns from the frames to build the path.describeagain to confirm. On a miss, repeat.
Tools
describe {udid}— focus view: the focused /[selected]element + focusable elements with labels and normalized frames. The discovery tool — call before and after navigating. Empty tree → see the per-platform notes.tv-remote {udid, button}— D-pad / remote.buttonis one key or a whole path (run in one call). Keys:up/down/left/right,select,back,menu,home,playPause, plus media keysrewind/fastForward/next/previous/volumeUp/volumeDown/mute. Single:{button:"down"}; repeat:{button:"down", repeat:3}; path:{button:["up","right","select"]}.keyboard {udid, text}— type into the focused field (focus it withtv-remotefirst). Namedkeypresses (e.g.{key:"enter"}) work on Vega; on Apple TV / Android TV move focus withtv-remoteinstead.launch-app/restart-app/reinstall-app {udid, bundleId}—bundleIdfrom the app manifest. Vegareinstall-apptakesappPath= a.vpkg.screenshot {udid, scale?}— Apple TV viaxcrun simctl io(downscaled); Android TV / Vega host-side viaadb/screencap.
Per-platform
Apple TV (tvOS simulator)
- Boot like any iOS sim (
boot-device); the AX + HID daemons auto-start on the firstdescribe/tv-remote(first call may take a few seconds). Give the RN bundle a few seconds to render before the firstdescribe. - Media-transport / volume keys are rejected — the sim's HID stack ignores them (they work on Android TV / Vega).
- Dev build:
open-url {udid, url:"<scheme>://expo-development-client/?url=http%3A%2F%2F<HOST_IP>%3A8081"}(<HOST_IP>= your Mac's LAN IP, shown on the launcher).
Android TV (leanback emulator)
- Boot the leanback AVD like any emulator — see
argent-android-emulator-setup. describemay report zero focusables on a screen with visible tiles: manyreact-native-tvosscreens use RN's own focus engine, invisible to the OS accessibility tree.describeauto-falls-back to the full UI tree (and says so in the hint);tv-remotestill moves focus, so drive blind +screenshotto confirm.- Dev build:
adb -s <serial> reverse tcp:8081 tcp:8081, deep-link<pkg>://expo-development-client/?url=http%3A%2F%2F10.0.2.2%3A8081, dismiss the first dev-menu withadb shell input keyevent KEYCODE_DPAD_CENTER(not Back — Back exits the app).
Fire TV (Vega / VVD)
list-devicesshows aserial(use asudid) and avvdImage.boot-device {vvdImage}(e.g."tv") starts the single SDK-managed VVD; skip if one already runs.- Stop the VVD with
vega virtual-device stopin your shell. The CLI only tracks VVDs it started in the foreground, so it may report "not running" for one started viaboot-device; to restart that one useboot-device {vvdImage, force:true}(stops then re-boots). - Empty
describetree →restart-app(the automation toolkit attaches at launch), then retry. Input ignored → enable developer mode in the VVD:vsm developer-mode enable. - Editing
node_moduleshas no effect on a Release build — only Debug.vpkgbuilds load patchable JS. - Profiling / crashes →

Common gotchas
- Empty focus right after
launch-app/restart-appis the splash / loading window —describeretries internally; wait ~2-3s and retry on a cold start. - Passing a phone/tablet (
runtimeKind: "mobile") udid totv-remotefails with a clear "tvOS-only" / "Android-TV-only" error — pick a TV target fromlist-devices.
Fast Refresh (dev builds)
Needs a Debug build + Metro running. argent only _connects_ to Metro — start Metro and port-forward yourself (any platform). Metro is fixed on :8081.
- Apple TV / Android TV: use the dev-build deep-links above;
npm startfor Metro. - Vega: build/install a Debug
