Every diagnostic line in the audio path used `dart:developer`'s `log()`.
That function writes to the VM service, which a RELEASE build does not
have — so in the only build that ever runs in a car, all eleven of them
went nowhere. `debugPrint`/`print` do reach logcat in release; `log()`
does not.
That includes the two channels built specifically to end the guessing:
- `registrarErrorAudioService`, which subscribes to
`AudioService.asyncError` so the plugin's swallowed platform exceptions
stop vanishing (b0271fa). It moved them from a dropped PublishSubject
to a dropped log call.
- `_trazarEstadoPublicado`, the published-state trace added in 7054a4c to
settle why the car's play button never becomes pause.
So "no evidence" was never a quiet app. It was an app writing its
evidence somewhere release builds discard. Several rounds of hypotheses
were argued without data that the app was already producing.
All eleven now use `debugPrint` with a `[PluriWave][Tag]` prefix, so one
filter catches the audio path and the existing alarm lines together:
adb logcat | grep PluriWave
No behaviour changes. Tests: 1158, unchanged.
Regression from the previous commit. Ranking every AudioDeviceInfo type this
build does not name individually ABOVE the built-in speaker was meant to let
a car stereo on LE Audio or an automotive bus win. It also promoted the
internal sinks a phone exposes permanently: on the Xiaomi test device
AudioManager reports TYPE_FM (14) as an output, so getActiveAudioDevice
picked it over the real speaker with nothing connected at all. Confirmed on
device:
audio_devices.onListen -> {id=other:14:4, type=14, name=2412DPC0AG}
It then reached Dart under an `other:14:4` id whose type is neither the base
speaker nor a known one, slipped past the collision guard and had a preset
row persisted for it -- reinstating the exact symptom this series set out to
kill: a permanent green active-output dot on a device that was not connected.
Replace the deny-by-omission ranking with an explicit allow list of outputs a
user actually connects. The built-in speaker sits below all of them and above
everything else, so any sink that physically exists but is never where media
plays (TYPE_FM, TYPE_BUILTIN_SPEAKER_SAFE, telephony, remote submix) can no
longer be selected. A one-time purge clears the `other:` rows the bad build
persisted; genuine ones re-register on their next connection.
Fix the USB type constant while here: TYPE_USB_HEADSET is 22, not 14, and 14
is TYPE_FM. The Kotlin USB branch hardcoded 14 and the Dart type table
mirrored the same mistake, so the two cancelled out for real USB headsets
while making a phone's own FM sink decode as USB audio. Both now use 22.
Verified with javap against android.jar (android-36) rather than trusting the
comment that introduced the error.
A Bluetooth device only reports its own name through
AudioDeviceInfo.productName while it is enumerated as an active output, i.e.
while it is connected. Paired-but-switched-off devices therefore had no name
to fall back on, and the platform-name cache is in-memory only by design
(bt-device-identity ADR-4), so it self-heals per session ONLY for whatever
happens to be connected. Every other device showed its raw id.
Android already knows those names: BluetoothAdapter.getBondedDevices() lists
every pairing with its name and MAC, connected or not, and nothing in this
app was asking. Read it and seed the platform-name cache from it, keyed
bt_a2dp:<uppercase MAC> to match the ids the audio layer emits.
Seeded BEFORE the active-device query so a live enumeration name, being the
fresher of the two, still wins; a user's custom name outranks both. Re-read
on refrescarDispositivoActual so pairing or renaming a device in system
settings shows up as soon as the list becomes visible.
Reading the bond list is gated by BLUETOOTH_CONNECT from API 31 and by the
legacy BLUETOOTH permission below it, so declare the latter with
maxSdkVersion 30. It is a normal permission: granted at install, no runtime
prompt, no new friction. When the answer is unavailable — permission denied,
no adapter, Bluetooth off — both layers return an empty map rather than
throwing, and the row degrades to the id exactly as before.
Does not help rows persisted under a bt_a2dp:name: placeholder id: those
never had a MAC to match against.
deviceToMap handed the builtin_speaker id to EVERY output type its `when`
did not name. A car stereo on LE Audio (TYPE_BLE_HEADSET) or an automotive
bus (TYPE_BUS) therefore arrived in Dart under the phone speaker's own id,
carrying a type that maps to `desconocido` -- which slipped past the
type-only esBase guard and persisted a device entry keyed builtin_speaker.
From that moment on, every playback through the phone's own speaker matched
that entry, so the green active-output dot stayed pinned to whatever the user
had renamed it to (a car, in the reported case) whether or not anything was
connected. The dot was never wrong; the row was poisoned.
Give unnamed output types their own `other:<type>:<address>` id namespace,
and match esBase by id as well as by type so no future native regression can
re-create the collision. A guarded one-time migration purges what the
collision already persisted from all three device-keyed maps.
Fix the ranking too: builtin_speaker sat inside the priority list as a peer,
so any type absent from that list sorted BELOW the always-present speaker
and could never win. The speaker is now the explicit last resort, externally
connected outputs outrank it, and virtual or call-only sinks (earpiece,
telephony, remote submix, SCO) are ranked below it so they can never be
reported as where music is playing.
Route every AudioDeviceInfo.getAddress read through a version-guarded
helper. It is API 28 with minSdk 24, and two pre-existing unguarded calls in
this same method were latent NoSuchMethodError crashes on Android 7-8.1.
Android lint for :app goes from 8 errors to 6.
Also lets the user manage the list, which is how they recover from a bad
entry without waiting for a release: a remove action clears a device's
preset, name and matrix entries, unnamed rows show their transport and
address tail instead of a raw bt_a2dp:AA:BB:... id, and the green dot
finally carries a tooltip and a semantics label saying what it means.
Device QA pending for wired and USB outputs: no jack or adapter available to
exercise those paths. Their detection is unchanged by this commit.
- MainActivity: onListen re-emits the current active device and registers
the audio device callback idempotently, so recreated activities resync
instead of freezing the active-device id on a disconnected device.
- servicio_dispositivo_audio: resubscribir() re-opens the event channel;
estado_ecualizador exposes refrescarDispositivoActual() with an
in-flight guard, invoked on app resume and when opening advanced EQ
options, clearing stale green-dot device selections.
- navegacion_auto/servicio_audio: new 'Personalizado' browse tree in
Android Auto (5 band folders, 13 gain steps each) applied live via
setBanda; preset and gain taps persist at device level when
multi-device EQ is active and respect station/matrix overrides,
with apply-before-persist ordering and children-changed notifications.
- l10n: regenerate stale generated localizations; add rxdart as direct
dependency for the subscribeToChildren override.
Dart half of bt-device-identity. EstadoEcualizador now caches each
device's platform-reported name in memory so the settings screen
shows the device's own Bluetooth name instead of its raw id when no
custom rename exists, and skips auto-creating preset entries for the
composite-placeholder sentinel. Enabling multi-device EQ triggers the
Bluetooth permission request through the new channel contract. A
flag-guarded one-time migration purges only entries keyed by the
exact literal placeholder id from the three per-device preference
maps, since those collided entries cannot be attributed to a device.
Work unit 2/2 of bt-device-identity (Dart state + migration).
Introduce multi-device EQ support allowing each audio output device
(built-in speaker, wired, USB, individual Bluetooth by MAC) to have
its own equalizer preset, combined with existing per-station presets
for a full station×device matrix.
