Dos fallos reportados desde el uso real en el coche.
Los grupos de favoritos no volvian al importar
La exportacion nunca estuvo rota: los grupos viajaban desde siempre y la
asignacion de cada emisora va dentro de cada favorito como grupo_id. El fallo
estaba solo al importar. La restauracion reutilizaba ServicioFavoritos.agregar,
que fuerza "sin asignar" a proposito, porque una emisora recien marcada como
favorita no tiene grupo. Correcto para esa ruta, destructivo como primitiva de
restauracion: los grupos volvian vacios y todo aterrizaba en Sin asignar. Se
separa la ruta de restaurar, que respeta el grupo_id del backup y su orden.
Ningun test lo detectaba porque el doble de pruebas era infiel: el fake
conservaba el grupo que la implementacion real destruia, y no tenia
restaurarGrupo, asi que esa ruta estaba sin cubrir. Los tests existentes lo
esquivaban pasando siempre una lista de grupos vacia. Se corrige el doble.
No hace falta subir la version del formato: el envoltorio ya llevaba todo.
El coche perdia la lista al reconectar
El contexto de reproduccion vivia solo en memoria, y el motor que arranca
Android Auto es un proceso nuevo sin interfaz ni EstadoRadio, asi que al
reconectar se reproducia la ultima emisora sin saber a que lista pertenecia y
siguiente/anterior no hacian nada hasta entrar a favoritos a mano. Ahora se
persiste el TIPO de contexto y, cuando aplica, el id del grupo, y se resuelve
contra las listas vivas en cada salto: si el grupo cambia de contenido entre
sesiones, el coche ve lo actual y no una foto vieja.
Cadena de repliegue, decidida por el propietario:
grupo vivo con la emisora dentro -> se recorre el grupo
grupo vivo sin la emisora -> se permanece en el grupo, primera
grupo vivo pero vacio -> se ensancha a favoritos
grupo borrado -> favoritos
sin favoritos -> comportamiento actual
Honrar un grupo de una sola emisora exigia levantar dos barreras, no una:
el resolutor y el propio _saltarEmisora, que se negaba a nombrar un grupo con
menos de dos miembros. emisoraVecina queda intacta: su contrato de no saltar a
ciegas es deliberado y se usa desde mas sitios, asi que el caso de "la emisora
se salio del grupo" se trata en el flujo del salto.
La puerta de entitlement no cambia: un conductor sin premium sigue recorriendo
solo el conjunto gratuito, y un contexto congelado mientras pagaba se descarta
en vez de recorrerse.
Suite completa: 1501 pasan, 2 omitidos. flutter analyze mantiene los 5 avisos
preexistentes.
The backup envelope carried favorites, EQ presets, alarms and the
multi-device toggle but not EstadoEcualizador's own on/off flag, so
restoring a backup on another device silently kept that device's
existing toggle state instead of the source device's.
Bumps the backup schema to v4 (additive over v3): the flag is only
written when explicitly provided, so old exports stay at v2/v3.
Importing an old backup without the field leaves the current toggle
untouched rather than defaulting it. Applying the imported value
reuses EstadoEcualizador.cambiarActivo so it persists and pushes to
the live audio engine exactly like a manual toggle.
Importing a backup wrote the alarm/vacation/exception block straight to
SharedPreferences but never told EstadoAlarmas about it, so the UI kept
showing the pre-import alarms, a later edit could persist that stale
state back over the imported one, and imported alarms were never
(re)scheduled with the Android native layer. The backup screen now
calls EstadoAlarmas.cargarPersistidasSinRecalcular() followed by
refrescarProgramacion() after a successful import, extracted into a
directly-testable aplicarImportacionConfig() function.
EstadoAlarmas, EstadoGrabacion and EstadoRadio defaulted `esPremium` to
`() => true`, so any construction site that forgot to wire entitlement
compiled fine and silently ran ungated — failing OPEN to premium and
disabling the paywall with no test able to catch it.
The parameter is now required with no default. Production wiring in
app.dart was already correct and is unchanged; the 184 pre-existing test
call sites now pass `() => true` explicitly, which is exactly the old
implicit default, so every assertion is untouched.
EstadoRadio has no gate of its own but constructs EstadoGrabacion, so it
inherits the same contract.
The one test that existed to pin the old default is renamed to describe
what it still covers (the premium path through iniciar() with no
duracion); its assertions are unchanged.
Adds a permanent, non-consumable premium unlock (EstadoEntitlement +
PuertoCompras/ServicioComprasPlayBilling) that removes ads and unlocks
alarm vacations, alarms past a 5-alarm free cap, recording start, and
full Android Auto browsing. The phone equalizer stays free for everyone.
- Entitlement is prefs-backed (compra_premium_v1), fail-open, and
resolvable headlessly via esPremiumPersistido() for the Android Auto
audio handler, which registers before runApp.
- Android Auto reduced mode keeps the real root folder labels for free
users; browsing into any of them (and playFromMediaId/playFromSearch/
skipToNext/skipToPrevious) is blocked at the getChildren/servicio_audio
choke points, with a locked "Función Premium" item as the backstop.
Current-station play/pause/stop stays untouched. A free -> premium
transition actively invalidates the head unit's cached browse tree.
- Ads (top banner + capped interstitial before adding a station or an
alarm) are gated behind entitlement via ServicioAnuncios, using
official Google test ad unit IDs pending AdMob provisioning.
- Alarm cap UX shows an explanatory message with a secondary unlock
action rather than a bare paywall jump; existing data is grandfathered.
- 4 new localization keys translated across all 13 supported locales.
Co-located tests use strict TDD (RED test before implementation) for
every new pure-logic unit; full existing suite passes unchanged.
Android Auto's Favoritos/Todas/Mis emisoras folders always re-sorted by
a hardcoded quality criterion in ConstructorArbolAuto.hijos/hijosGrupo,
discarding whatever order the caller passed in. EstadoRadio now pushes
already-ordered snapshots (listaFavoritosManual for Favoritos, and the
ordenListas-sorted populares/emisorasCustom getters for Todas/Mis
emisoras, re-pushed immediately on cambiarOrdenListas), and hijos/
hijosGrupo stop re-sorting so that order survives into the car.
EstadoRadio.emisoraActual only ever reflected in-memory state
(_emisoraSeleccionada or the live audio service), so stopping playback
and reopening the app left the Escuchar hero empty even though the
user had a station selected right before closing it.
Persist the station whenever it changes (reproducir(), and the
Android-Auto out-of-band reconciliation path) and restore it as
_emisoraSeleccionada on the next cold start, only when nothing is
already selected. This never touches the audio service directly: no
playback starts and estadoStream/estaSonando stay at their stopped
default, matching how every consumer already gates "is it playing" on
the playback-status stream rather than on emisoraActual itself.
Replaces the stacked per-group panel layout with a single
chip-filtered flat list. Chips read "{name} · {count}" (new ARB keys
favoriteGroupsChipLabel/favoritesFilterAllLabel), one per group plus
an "All" chip. Rows drag-reorder via a leading handle
(ReorderableDragStartListener, buildDefaultDragHandles: false) using
the modern onReorderItem callback rather than the now-@Deprecated
onReorder (Flutter 3.44 marks it obsolete).
EstadoRadio additions: listaFavoritosManual (a new memoized getter
returning the stored order untouched by the global ordenListas
setting - listaFavoritos itself always re-sorts by
name/quality on every read, which would silently discard any
drag-to-reorder), reordenarFavorito (thin wrapper over the
already-existing ServicioFavoritos.reordenar, previously unused
outside its own service test), and ordenarFavoritos (applies an
existing OrdenEmisoras criterion via ordenarEmisoras() and persists
the result as the new manual order, so the swap_vert sort action's
result also survives a restart). listaFavoritos itself is untouched,
so Android Auto's tree and the future Escuchar grid (WU5) are
unaffected by Favoritos' own manual order.
Group management: an "Manage lists" action chip pushes the existing
PantallaAjustesGruposFavoritos screen (Settings' own screen, reused
rather than duplicated) - a second entry point to the same screen.
Custom-station CTA: a new dashed-bordered card opens the add-station
form directly; that form was renamed from private _FormularioEmisora
to public FormularioEmisoraPersonalizada in
pantalla_ajustes_emisoras_personalizadas.dart so both screens share
one implementation. New ARB keys: favoriteGroupsManage,
customStationsAddCta.
Tests: pantalla_favoritos_plural_test.dart (the file tasks.md named)
never imported PantallaFavoritos - it only covers stationCount's ARB
plural formatting, unrelated to this screen. Left it untouched and
added test/pantallas/pantalla_favoritos_test.dart instead: 3
state-layer tests for the new EstadoRadio surface plus 6 widget
scenarios (empty-state CTA, chip filter, drag-reorder persistence,
sort action, group management + chip reactivity, custom-station
CTA). 604 -> 614 tests (2 skipped, unchanged). flutter analyze
unchanged at 1 pre-existing info.
Recorded in tasks.md with the test-file correction and the
design decisions this WU had to make on its own (no ADR covers
Favoritos' manual-order persistence).
Favoritos now renders non-empty custom groups as grupo:<id>
sub-folders (hidden when empty) with ungrouped stations left as
direct leaves, reusing the existing hijos() path so the zero-groups
case stays byte-identical to today's flat list.
Expose PluriWave to Android Auto (projected) as a media app:
- Declare car media support (automotive_app_desc.xml + manifest meta-data)
so Android Auto discovers the existing MediaBrowserService.
- New navegacion_auto.dart: ConstructorArbolAuto builds the browse tree
(Favoritos / Todas las emisoras / Mis emisoras, 50-item cap, stable
emisora:<id> media ids), reproducirPorMediaId routes a car tap to the
existing playMediaItem pipeline, FuenteEmisorasAutoLocal serves the tree
cold-start-safe (local favorites/custom stations before Flutter UI runs).
- PluriWaveAudioHandler overrides getChildren/getMediaItem/playFromMediaId
as thin delegations; playback pipeline untouched.
- EstadoRadio pushes live station snapshots to the browse source and
reconciles the selected station when playback starts from the car.
- Every playable item ships title + artUri; stations without logo fall
back to a bundled default art (android.resource://).
Tests: 52/52 green (10 new navegacion_auto, 2 new estado_radio, plus
audio safety-net suites). Handler overrides and native XML are
static-review-only (no Android build env). Size exception approved for a
single reviewable commit.
_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.
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.
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.
- Add DispositivoAudio model and ServicioDispositivoAudio interface
- Add Android platform channel (AudioDeviceCallback) for device detection
- Add iOS AudioDevicesPlugin (AVAudioSession route tracking)
- Extend ServicioEcualizador with device and matrix persistence keys
- Implement 4-level resolution: matrix > station > device > global
- Add advanced EQ settings section with feature toggle (off by default)
- Extend export/import to v3 with backward compatibility
- 184 tests passing, zero analyzer issues
- New EstadoGrabacion owns the recording service, subscription, directory/size preferences and open-file actions
- New EstadoBusqueda owns search, nearby stations, pagination and the min-bitrate filter
- New orden_emisoras.dart with the OrdenEmisoras enum, shared sorter and list identity memoization so context.select comparisons work on derived lists
- Large screens (inicio, buscar, favoritos, ajustes, reproductor) consume scoped selects/dedicated notifiers instead of root context.watch<EstadoRadio>, so audio buffer events no longer rebuild whole screens
- Remove all 15 TODO(S4b) compat members from EstadoRadio; consumers use the dedicated providers. EstadoRadio drops from ~1121 to 753 lines, keeping playback/stations/favorites orchestration
- 8 new tests including a rebuild-scoping probe (110 total green), flutter analyze clean
- New ServicioExportImport owns the v2 backup envelope, pretty JSON encode and graceful decode; byte-compatible with existing exports, locked by a round-trip test
- pantalla_ajustes delegates backup serialization to the service (inline jsonDecode/jsonEncode removed)
- New EstadoEcualizador ChangeNotifier owns all EQ state and persistence (principal/current/per-station presets, active flag), exposed via its own provider so EQ changes no longer rebuild EstadoRadio consumers
- EstadoRadio slims down ~210 lines and keeps 15 delegating compat members marked TODO(S4b) for the next slice to remove
- Player EQ toggle rewired to the new provider to avoid going stale
- 4 new tests (103 total green), flutter analyze clean
- Integrate audio_session (new servicio_audio_session.dart): incoming calls pause the radio and resume on end, headphone unplug pauses without auto-resume, permanent focus loss never auto-resumes, duck lowers volume
- Add play-intent flag to ServicioAudio so interruption handling and future reconnect logic can distinguish user pause from system-driven stops
- Eliminate read-modify-write race in ServicioAlarmas with an in-memory cache and single-writer queue across all mutations; recalcularTodas persists only when state actually changed
- Convert ServicioAlarmasAndroid static StreamController/handler to injectable instance fields, restoring test isolation
- Inject a single cached SharedPreferences from main.dart across services and state (removes 23 inline getInstance() calls)
- Move configurarLocalizaciones out of MiniReproductor.build() (was running on every rebuild during playback)
- Bound the alarm fire-dedup set (cap 200 entries, 24h pruning)
- 12 new tests (89 total green), flutter analyze clean
- Added state management for startup retry and custom station handling in `EstadoRadio`.
- Created tasks for implementing strict TDD with RED tests for HTTP failure retries and EQ persistence.
- Developed verification report to ensure compliance with TDD practices.
- Introduced fake services for testing, including `FakeServicioAudio`, `FakeServicioFavoritos`, and `FakeServicioRadio`.
- Implemented widget tests for `PantallaInicio` and `PantallaFavoritos` to validate UI behavior with custom stations.
- Enhanced `ServicioRadio` to support host rotation and retry logic for API calls.
- Established a new configuration file to enforce project constraints and testing rules.
**Fix 1 — HTTP cleartext (streams sin HTTPS):**
- Añadir android/app/src/main/res/xml/network_security_config.xml con
cleartextTrafficPermitted=true para permitir streams de radio HTTP
- Referenciar en AndroidManifest.xml con android:networkSecurityConfig
- Resuelve: 'Cleartext HTTP traffic to [host] not permitted' en ExoPlayer
- Radio Paradise (Dance Wave, HTTP) y otras radios HTTP funcionan ahora
**Fix 2 — Gestión de error TYPE_SOURCE y todos los PlaybackException:**
- Añadir listener en playbackEventStream.onError en PluriWaveAudioHandler
- _gestionarErrorReproduccion() emite AudioProcessingState.error al UI,
loggea el error y resetea el player a estado idle limpio
- _mensajeAmigable() traduce códigos ERROR_CODE_IO_*, ERROR_CODE_PARSING_*,
ERROR_CODE_DECODING_* y mensajes de Cleartext/HandshakeException a texto legible
- EstadoRadio.reproducir() captura la excepción y cancela el timer si estaba activo
- EstadoRadio escucha el estadoStream y cancela timer ante cualquier error
**Fix 3 — Artwork con certificado autofirmado:**
- errorWidget en CachedNetworkImage captura HandshakeException silenciosamente
- Muestra _iconoFallback (icono de radio) en lugar de imagen rota
- El error de artwork no se propaga ni interrumpe la reproducción
**Fix 4 — UI consistente en estado de error:**
- PantallaReproductor._Controles muestra mensaje + botón Reintentar en error
- PantallaReproductor._Artwork muestra overlay wifi_off en estado de error
- MiniReproductor muestra botón refresh (reintentar) en estado de error
- EstadoReproduccion.error ya estaba definido; ahora el estadoStream lo emite
- Timer cancelado automáticamente cuando la reproducción falla
- Test de smoke corregido (boilerplate MyApp → placeholder válido)
Fixes: cleartext HTTP, cert autofirmado, ExoPlayer TYPE_SOURCE, UI inconsistente
- ServicioAudio: delega a PluriWaveAudioHandler (audio_service) para
mantener audio vivo en background. AudioService.init() en main.dart.
onTaskRemoved() libera player. mediaItem con nombre/artista/artwork.
- ServicioRadio: lastcheckok=1 en todas las peticiones — solo emisoras
verificadas como funcionales por Radio Browser API.
- EstadoRadio: errorStream (broadcast) para errores de reproducción y
búsqueda. App.dart suscribe y muestra SnackBar flotante 3s.
Los errores de carga de lista siguen como banner inline.
- Icono: generado con SDXL (morado, ondas radio blancas, Material You).
5 densidades Android (48-192px), ic_launcher_round añadido.
