The recordings live in app-private storage (<data>/app_flutter/grabaciones),
which the Android sandbox forbids any other app from reading, so no
ACTION_VIEW on a file:// or FileProvider URI could ever open it. On top of
that, viewDirectory built an EMPTY candidate list for that path:
directoryDocumentUri returned null (path outside external storage) and
FileProvider.getUriForFile threw because pluriwave_file_paths.xml never
covered app_flutter. The loop never ran, so both entry points -- the radio
recorder and Settings -- always showed "could not open the folder".
Publish the folder as a browsable storage root via
RecordingsDocumentsProvider instead. The files never leave private storage;
the document framework asks us for them one document at a time, and the user
can browse, copy out, rename and delete straight from the file manager. The
root follows a user-configured path and falls back to the default recordings
directory. Its title reuses the already-translated recordingsFolderTitle, so
no new literal is introduced in any of the 13 locales.
Also fixes "open last recording", broken by the same missing FileProvider
root, and replaces Intent.createChooser with a bare startActivity in the
candidate loop: a chooser never throws when nothing can handle the intent, so
the first candidate always "succeeded" and the fallback chain never ran.
Device QA pending -- the provider is driven entirely by the platform's
document framework, so no unit test covers it. Each candidate logs its own
name under file_actions.viewDirectory for logcat triage.
Android Auto no longer copies the launcher icon as placeholder art; it
rotates through the same 4 on-brand station_art assets the phone UI
already uses, keyed by the same per-station hash for visual parity.
Malformed or unusable favicon URLs (including a Dart Uri quirk where
'http://' reports hasAuthority=true with an empty host) now fail the
validity gate instead of being handed to the OS media browser as-is.
Browsable items also show codec/bitrate as a subtitle when known.
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.
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.
**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.
