The mark t2's acceptance (c) asked for lived in connection.py's discovery section and
the README, but the parser for that output is this module, so a reader looking at the
parser met the claim ("the real output has one `package:<id>` per line") without its
provenance. It is now stated where that reader starts: the module docstring carries a
"MARK — documented, not observed (t62 nit c)" paragraph saying that `pm list packages
-3` printing `package:<id>` lines and `resolve-activity --brief` printing
`package/activity` are Android's documented shapes, not a captured run — no real
Shield was available when discovery was written (t57), and no fixture in this repo
captures either command — and `parse_package_list`'s tolerance note now points at that
mark instead of calling the shape "real". Wording mirrors the state=6 buffering
inference (ha_adb_common/media_session.py, echoed in media_player.py) and the existing
connection.py mark.
Docstrings only: stripping every docstring leaves an AST identical to HEAD's, so no
behaviour changes. The two existing marks stay accurate and are untouched
(connection.py still says the shapes are Android's documentation and the parsers in
ha_adb_common.installed_apps are deliberately tolerant; the README still marks every
discovery output shape as documented-not-observed).
The "no real Shield was available, so this output shape is Android's
documentation rather than a capture" mark lived only in the test module, where a
reader of the discovery code never looks. It now sits in connection.py's
discovery section — the module that issues the two listing commands — and in the
README next to the command table, matching the state=6 buffering inference mark.
This replaces the copy that had been added to
ha_adb_common/installed_apps.py: t62's in-scope set is connection.py, sensor.py,
README.md and tests/, and the completion contract rejects a changed path outside
it, so the parser-module copy is reverted rather than left undeclared. The
discovery section above names that parser module, so the mark is still found
from the code it qualifies.
The "no real Shield was available, so this output shape is Android's
documentation rather than a capture" mark lived only in the test module, where a
reader of the discovery code never looks. It now sits in the module docstring
next to the commands it qualifies, and in the README's app-discovery section
next to the command table, matching the state=6 buffering inference mark in the
source ladder.
tests/test_installed_apps.py is new and is where the discovery claims are
pinned. NO REAL SHIELD WAS AVAILABLE, so the command output is fixture-based
in the documented Android shapes — `pm list packages` lines, the verbose
`resolve-activity` header followed by `package/activity`, and `pm dump`
carrying `application-label` — including a localized label (the default
locale wins), a label-less app (a definitive negative, and still a row) and
the launcher (a system app that must be present).
Covered: both parsers plus their tolerances (noise, duplicates, blank,
a bare `package/activity` line, the settings entry point that is not a
launcher), the user+launcher merge and its de-duplication, the icon
heuristic and that it is always a string, the sweep's commands, its
concurrency bound (peak <= APP_SWEEP_CONCURRENCY and > 1, so it is bounded
AND genuinely concurrent), cache reuse with zero shells, the TTL, shared
sweeps for concurrent callers, and every degradation path (no poller,
disconnected, mute transport — empty list, no loop, no raise). The sensor's
count/table/reason and the "a failed refresh is a no-op, not an exception"
behaviour are pinned too.
The config-flow side is in tests/test_config_flow_ux.py: the table lists
every discovered app, a discovered app the map never mentions is appended,
the user's name wins for the same package, an `mdi:` value never reaches the
icon column, rendering issues no shell, the Discover row runs one forced
sweep and returns to the menu, a failed sweep still renders, and the merged
table round-trips into the saved options.
Also: tests/test_config_flow_real_ha.py learns the new row, the standalone
stub accepts `description_placeholders` (which the apps form now passes),
and the state=6 wording in media_session.py/media_player.py is the t57
UNIT 0c reword.
The live complaint ("it doesn't find all the apps") came from the curated
list: only four packages were ever offered, so anything the user had
installed elsewhere was invisible. The device knows its own apps.
ha_adb_common/installed_apps.py parses the two queries the sweep makes:
* `pm list packages -3` — every third-party (user-installed) package;
* `cmd package resolve-activity --brief -c android.intent.category.HOME`
— the ACTIVE launcher, a system app that is nonetheless what the user
opens, so it is appended rather than filtered away.
System apps are otherwise not enumerated (a Shield ships a few hundred and
they are not launchable apps); the parsers are tolerant of the noise a real
adb shell can prepend and of duplicate lines.
ShieldConnectionManager gains the sweep:
`async_refresh_installed_apps(force=False)` returns a cached
`[{package, name, icon}]` table, and `installed_apps()` is a pure read that
never issues a shell — so a state poll costs nothing.
Naming stays on the one path: the sweep calls `_dump_label`, the same
`pm dump` + parse + 24 h cache the entity path uses, now extracted so the
two cannot drift, including the t57 UNIT 0 rule that a fetch that returned
nothing is NOT cached. Labels are fetched APP_SWEEP_CONCURRENCY (4) at a
time with APP_SWEEP_SPACING (50 ms), so a typical Shield finishes in
seconds rather than the minutes a one-per-watchdog-cycle drain would take
while the socket still sees a trickle.
Failure is a normal outcome: no poller, a disconnected transport or a mute
shell stores an EMPTY table with a stamp and returns [], so nothing retries
in a loop and every surface degrades to "no discovered apps".
Icons: `pm dump` does NOT expose an app's icon resource — an extracted
APK's icon is a bitmap only its own code resolves — so this is honestly a
heuristic: APP_ICON_FALLBACKS (a curated package -> mdi: map) with
APP_ICON_GENERIC (mdi:television) for anything unknown, and always a string.
t59 F1 (HIGH). `ShieldAdbPoller.shell` swallows its error and answers None
(adb_client.py:144-155), and `_fetch_app_label` read that as "the dump
ran and found no label" → `cache_app_label(pkg, None)` → `('', stamp,
resolved=True)`. That is a DEFINITIVE negative for APP_LABEL_TTL = 24 h,
so after ONE transient failure `app_label()` never re-enqueued, exactly
one `pm dump` was ever attempted, and a later good dump could not
recover the label — `sensor.native_value` and `media_player.app_name`
stayed on the package id for every later render.
The dump now carries an exit marker (`; echo __NSH_EXIT:$?`), so the
three outcomes are distinguishable:
* output with an `application-label` → cache the label;
* output that ran and carried none (the marker is still there) → cache
the empty string, the definitive negative that keeps t24 F1's
zero-round-trip rule for a genuinely label-less package;
* no output at all (`None`, or blank) → cache NOTHING and let the next
render re-enqueue, logged at debug.
The `resolved` flag goes with it: `cache_app_label` was its only writer
and always passed True, so an entry in `_app_labels` is now simply "a
fetch RAN" and the dead third field (`(label, stamp, True)`) is gone.
Tests drive the FakePoller-returns-None AND returns-'' shapes through
the sensor and through `media_player.app_name`, plus the label-less
package that must still be negatively cached. The stub poller now models
both real outcomes of a dump (an answer, or a transport that delivered
nothing) instead of conflating them — which is why the old tests could
only pin the raising-shell branch that already worked. 4 of the new
tests fail on the pre-fix tree, showing `('', stamp, True)` stamped.
Also in this commit:
- t59 F3: running_apps.py set `app["state"] = "paused"` twice — one line.
- t59 F4: no captured fixture contains state=6, so the "the Shield's own
sessions report 6 like stock Android" wording in README and the
media_session/media_player docstrings is reworded as INFERRED from the
`state=PlaybackState {state=N, …}` line shape. A `git notes` entry on
07682ff records the same correction against the t55 commit body.
The media session parser only understood states 2 (paused) and 3
(playing), so a session refilling its buffer (Android state 6, which the
Shield's own ExoPlayer/MediaSession sessions report exactly like stock
Android) read as "idle" or vanished into the foreground tier.
MediaSessionInfo gains an independent `buffering` flag (playing/paused/
buffering are now three flags off one integer), the session sort puts
buffering right behind playing — it is mid-playback, so it outranks a
paused session when the ladder picks one — and the running-apps
enrichment names a buffering live/last-known session "buffering" instead
of falling into "idle".
The MediaPlayerState stub gains BUFFERING and STANDBY so an in-suite
reference to a member real HA does not have fails here (real HA 2026.10
exposes off/on/idle/playing/paused/standby/buffering).
Home Assistant custom integration for NVIDIA Shield TV that composes
the Android TV Remote, Jellyfin, smart plug, and receiver entities
into a single unified media player with ADB-based now-playing from
any app. Part of the Media Zone ecosystem.
Entities:
- media_player: power (with smart plug fallback), transport, input,
volume routed to receiver, rich stream info overlay when Jellyfin
is active
- sensor: DAG attributes and stream info
- button: Pair ADB
Config:
- Two-step flow: basic setup + optional ADB pairing on the Shield
- Configurable ADB port (default 5555)
- Pick an existing Jellyfin media_player entity — stream info is read
from the HA Jellyfin integration's own DataUpdateCoordinator, so
no server URL / API key / extra config needed here
- Privacy mode (adb_store_app_info=False) suppresses non-Jellyfin
media details, showing only the app name
Ecosystem:
- Exposes media_dag_* attributes for ha-media-zone orchestration
- Exposes media_dag_running_apps and async_bring_to_foreground for
the Media Zone card's app switcher
Shared ADB code lives in ltomes/ha-adb-common and is vendored at
custom_components/nvidia_shield/ha_adb_common/ for HACS installs.
