PantallaAlarmaSonando no longer owns any audio orchestration (fallback
player, dB ramp, native handoff confirm, media-volume override/restore):
it only calls EstadoAlarmas.finalizarEjecucion/posponerAlarma from
Stop/Snooze/back, keeping the single-exit guard, PopScope back=Stop and
dismiss semantics intact. The status line now reads directly from the
alarm's static config (station name or a neutral label) instead of a
live playback/handoff state.
PuertoAlarmasAndroid drops confirmarAudioFlutter,
forzarVolumenMediaParaAlarma and restaurarVolumenMedia, and app.dart no
longer pre-starts a station before pushing the ring screen. This is the
Dart half of moving to a single native ring-audio owner (WU1 of 2); the
Kotlin service rebuild lands next and keeps this intermediate state
shippable with no double audio.
On-device logcat from the latest test showed two defects the previous
design created. The fade-in was gated on the station reaching
`reproduciendo`, and the stream took 18.7 seconds to buffer: the ring
sat frozen at 5% the whole time and the configured fade seconds only
started counting afterwards. And the stream override was raised during
pre-start, so the ExoPlayer AudioTrack spin-up — which runs at gain 1.0
for an instant before the player gain lands — blasted at the configured
ring level, heard as "starts directly at the alarm volume".
The ramp is now anchored at alarm time: it starts when the screen
starts, buffering just joins it at the elapsed level, and the fade
duration means seconds-from-alarm. _iniciarFadeIn is single-start so
the handoff confirmation and fallback paths can no longer restart an
in-progress ramp from 5%. The stream override moved from the app-side
pre-start into the screen and is raised only when audio is actually
about to flow (first `reproduciendo`, the already-playing branch, or
right before the fallback WAV plays), so track spin-up happens under
the user's original low volume and the blast is physically impossible.
Exit teardown restores the device stream before resetting the player
gain, removing the brief exit blip seen in the capture.
Two exit-path holes found by adversarial review before the next build:
PluriWaveAlarmService.stopAlarm() never compared the requested id to
activeAlarmId, so any stop request for a DIFFERENT alarm tore down
whichever ring was active: with two alarms firing close together, the
second one's routine hide-notification call (via dismissAlarmNotification
-> ACTION_STOP) killed the first alarm mid-ring and prematurely restored
the device volume override. A mismatched id now only cancels that id's
notification and returns; null keeps full-teardown semantics for
internal/onDestroy callers.
The ringing screen never intercepted the system back gesture: a plain
route pop ran only dispose(), leaving the shared radio player ringing
with no alarm UI left anywhere to stop it. Back now routes through
PopScope into the same _detener() flow as the Stop button, guarded by a
single-exit flag so a back-press racing a button tap cannot run the
teardown twice and pop the route underneath.
Also resets the shared handler gain to 1.0 on ring exit: the fade-in
mutates the radio player's persistent volume, and exiting mid-ramp used
to leave every later radio play at the partial ramp level.
The ring-scoped media override forced STREAM_MUSIC to the hardware
maximum, so the alarm's configured percentage was applied on top of a
maxed speaker: "50%" meant 50% of the phone's absolute maximum and
the fade rode against that ceiling, far louder than the device-
relative level users were used to. On-device logcat also showed the
just_audio player emitting one buffer at volume 1.0 before the 5%
pre-start took effect, a full-scale click on the maxed stream.
The stream is now capped at the alarm's configured volume (still
independent of the device's own level, so it rings at device-volume
0), and the player ramps from ~5% up to its full range under that
cap. Perceived peak is the configured fraction of the device maximum,
reached gradually; the opening click drops to the configured fraction
instead of full scale.
The live eventosAlarma stream and the one-shot obtenerEventoInicial()
both read the same native fire event on cold start, so the same alarm
id can reach _mostrarAlarmaSonando twice within the same tick. The
second, duplicate delivery correctly detected an alarm was already
active and hit the "ignored" branch — but that branch unconditionally
called ocultarNotificacionAlarma, whose native handler
(dismissAlarmNotification) unconditionally stops
PluriWaveAlarmService for that id.
Confirmed via on-device logcat: the duplicate's stop landed ~180ms
after the ring-scoped media-volume override was captured and ~2.3s
before the real native-to-Flutter handoff, so flutterOwnsRing was
still false and the teardown backstop restored the device's original
volume immediately. The Flutter/radio player kept ringing regardless
(it starts independently of the native service), now anchored to
whatever volume the device happened to be at — explaining both
"ignores the configured ramp" and "plays at the device's own volume."
The ignored branch now only hides the notification when the duplicate
carries a genuinely different alarm id than the one already ringing;
a duplicate of the SAME ring's own event is now a pure no-op.
_cargarEmisorasCustom resolved the file path outside the IO guard, so
a throw from the resolver escaped into _init()'s Future.wait and took
the sibling loads (populares, favoritos, grupos) down with it — a gap
the old catch-all used to cover. Path resolution now gets the same
IO-fail treatment as an unreadable file: degraded flag, logged skip,
siblings unaffected.
Convert the 4 EQ persistence readers (device presets, matrix presets,
device names, per-station presets) to per-entry tolerant parsing via
the shared persistencia_tolerante helper, so one corrupt entry no
longer discards every sibling preset. The principal-preset reader
gains diagnostic logging on its existing fallback path. No degraded
flag or quarantine here (unlike alarms/stations) since EQ writes are
explicit-only and presets are trivially re-creatable.
A single malformed custom-station entry (missing uuid/url) used to wipe
the ENTIRE list on next load, and an unparseable file was treated the
same as an unreadable one -- both destroyed the user's saved stations
with no way to recover the original bytes.
Custom stations now parse per-entry via the shared persistencia_tolerante
helper (survivors kept, bad entries skipped+logged); a file that reads
but fails to decode is quarantined into a `.corrupt` sidecar instead of
being dropped, clearing the live path so the next add/remove starts
fresh. A file that cannot be READ at the OS level is left untouched and
a _customDegradado flag suppresses writes for the session -- unlike
alarms, this suppression is intentionally not lifted by an explicit
add/remove, since the file may still be intact on disk.
A single malformed alarm entry (bad/missing id, wrong type) used to
discard the ENTIRE persisted list on next load, and a fully unparseable
payload let the periodic recalculation silently overwrite it with an
empty one -- both destroyed valid alarms with no user action.
Adds a shared per-entry tolerant-parse helper (persistencia_tolerante.dart)
that skips and logs only the bad entry; ServicioAlarmas now normalizes its
cached raw after a partial load (no dirty-guard thrash) and sets a
degraded-read flag after a total decode failure that suppresses automatic
writes until a good read or an explicit user mutation restores authority.
The ringing screen only confirmed the native-to-Flutter handoff from
its playback-state listener, but app.dart pre-starts the station
before pushing the screen, so `reproduciendo` could be emitted before
the listener subscribed and no further event ever arrived. That
branch only cancelled the fallback timer: the gated fade-in never
started and the native alarm player was never told to stop, so the
alarm blared at the alarm-stream volume with no 5%-to-target ramp.
Previously this was a timing race the stream usually lost; gating the
ramp on the confirmation made the failure deterministic.
The already-playing branch now confirms the handoff explicitly
(idempotent with the listener), and the ramp re-imposes its 5% start
volume immediately instead of waiting for the first periodic tick.
Adds the regression test mounting in the real pre-started path.
_restaurarVolumenMediaUnaVez() read the BuildContext to reach the
alarm port, but dispose() runs after the element is defunct, so the
lookup always threw (caught and logged) and the dispose safety-net
never actually restored the media volume when it was the sole exit
path. The state is now captured once in initState and the restore
helper uses the field. Adds the missing dispose-as-sole-caller
regression test.
The native service and the Flutter player each ran their own 5%-to-
target fade-in, and both could drive audible volume at the handoff,
producing a jump or ramp reset. The Dart ramp now starts exactly once
from the handoff-confirmation path: the player still pre-starts at 5%,
and _confirmarAudioFlutterListo() starts the ramp in a finally block
so it runs whether the native confirmation succeeds or fails — the
alarm can never stay stuck at 5% if the native side is already gone.
Work unit 3/3 of alarm-volume-ramp-restore (fade-in dedup).
The alarm's steady-state audio runs on the Flutter media-stream
player after the native handoff, so device volume 0 silenced it
entirely. The ring now forces STREAM_MUSIC to an audible reference:
Dart requests the override before pre-starting alarm audio (fallback
WAV included), Kotlin captures the current volume once and restores
it idempotently on every exit path (dismiss, snooze, dispose), with
a native best-effort backstop in service teardown.
The backstop is handoff-aware via PluriWaveAlarmService.flutterOwnsRing:
confirmFlutterAudio marks the handoff before triggering the native
stop, so the backstop cannot restore the volume mid-ring right as the
Flutter player takes over (that would re-silence the alarm at volume
0). The flag resets at every ring start; Flutter process death after
handoff remains a documented best-effort gap.
The alarm's perceived loudness keeps ramping 5% to the configured
volume through the player as before; normal radio playback and call
ducking never touch the override.
Work unit 2/3 of alarm-volume-ramp-restore (ring volume 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).
_onDispositivoCambiado() bootstrapped a device-level preset entry for
every never-seen device id, including the built-in speaker. That
persistent level-3 entry masked later global-preset edits (level 3
beats level 4 on every resolution), so disconnecting a BT device or
cold-starting without one could leave the EQ stuck on an outdated
copy instead of the current global preset.
The base speaker is now excluded from the first-seen bootstrap:
disconnect and cold start always resolve through the live hierarchy.
BT/wired/USB devices keep their bootstrap behavior unchanged.
ExoPlayer assigns a new audio session id after transient audio-focus
interruptions (navigation prompts, radar warnings), leaving the
AndroidEqualizer attached to the dead session so playback resumed
without equalization until the next station switch. The session-id
listener now detects genuine rotations through a dedicated guard and
re-activates the equalizer with the current preset, gated on EQ
availability to stay clear of player teardown/rebuild.
Replace generic system icons (info bubble, stock alarm clock) with a
custom equalizer-bars vector drawable across all 4 notification
builders: pre-notice, snooze countdown, ringing alarm, and the audio
player. Apply the app's cyan brand color to the 3 alarm notifications
that previously had none. Audio notification now explicitly declares
its icon instead of falling back to the full-color launcher icon,
which Android was auto-silhouetting into an illegible status-bar
blob.
guardarAlarma only recomputed proximaEjecucion for the alarm being
saved; every other alarm kept whatever snapshot the last periodic
recalculation left, which can be stale or already past-due. Since
EstadoAlarmas.proximaAlarma just sorts by proximaProgramable, a stale
sibling could wrongly outrank a freshly activated/created/edited
alarm in the "Próxima alarma" panel until the next 1-minute tick.
Extended the same full-list recalculation guardarVacaciones already
did to guardarAlarma, eliminarAlarma, completarEjecucion,
sincronizarEjecucionesNativas, saltarProxima and
posponerEjecucionHasta, via a shared _recalcularLista helper.
posponerAlarma() and posponerProximaDesdePreaviso() called the native
scheduler with no error handling, unlike guardarAlarma(). When the
native call failed (e.g. revoked exact-alarm permission), the
exception escaped before notifyListeners() ran, leaving the alarm
list stuck on stale data with no real alarm scheduled and no snooze
countdown notification.
Both methods now mirror guardarAlarma()'s pattern: permission
pre-check, try/catch into _error, and an unconditional
notifyListeners() so the UI always reflects the outcome. Failures
surface via SnackBar in the ringing screen and in app.dart's
postpone-next handler.
Centralize every native-side user-facing string in a single
AlarmNotificationStrings store written by Flutter via a new
setNotificationStrings MethodChannel whenever the app locale changes,
and read at notification/channel build time (with English fallbacks)
even when the engine is dead. This replaces the hardcoded Spanish text
in the ringing notification ("Alarma PluriWave", "Posponer", "Detener"),
the pre-notice notification ("Posponer", "Omitir esta vez"), both
notification channels (names + descriptions) and the file-action
choosers ("Abrir carpeta", "Abrir grabación").
The per-alarm preNoticeTemplate/snoozeCountdown template+label args are
dropped from scheduleAlarm and the persisted spec and folded into the
shared store, so a locale change now also relocalizes already-scheduled
alarms. Channels are re-created on each use so their name/description
refresh after a language switch.
Adds alarmRingingNotificationTitle, alarmFire/PreNoticeChannelName,
alarmFire/PreNoticeChannelDescription and openFolder/openRecording
chooser keys across all 13 locales (reusing snoozeAction, stopAlarmAction,
skipNextAction, snoozeAgainAction). Rewrites the template test around
setNotificationStrings. Kotlin is static-reviewed only; no Android build
environment available here.
The snooze button was fire-and-forget without error handling: if
posponerAlarma threw (e.g. native scheduleAlarm returns false on a
device without exact-alarm permission), _dismissScreen never ran. The
stuck modal also kept _alarmaSonandoActiva true, which made the next
ring get ignored. _posponer/_detener now dismiss in a finally and stop
audio defensively.
Add a native, AlarmManager-driven snooze countdown notification that
re-posts every minute ("Rings in N min", 3->2->1) while the engine is
dead. scheduleSpec drives scheduleSnoozeCountdown for snoozes (instead
of the 30-min pre-notice). Localized text and button labels travel
Dart->Kotlin as {minutes} templates, same pattern as preNoticeTemplate.
Notification actions: "snooze again" (snoozeAgain, anchored to now)
reports back via the existing snoozed event; "stop" (cancelSnooze)
records a handled occurrence for cold-start reconciliation and emits a
new snoozeCancelled event handled in EstadoAlarmas.
Adds snoozeCountdown/snoozeAgainAction keys across all 13 locales and a
test for the snoozeCancelled event. Kotlin changes are static-reviewed
only; no Android build environment available here.
Replace hardcoded Spanish pre-notice text with computed remaining
minutes using l10n template passed via MethodChannel. Fix snooze
dismiss in dead-app state with canPop guard and SystemNavigator.pop
fallback.
Fix multi-device EQ auto-switching by calling obtenerDispositivoActual()
during cargarPersistido() to seed the initial device ID. Add device
management modal with rename support, EQ preset editing, and connection
status indicator. Translate device UI keys to all 13 locales.
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.
