# GPS2Audio v2.7.33 — Handoff

UI-only polish of the Begleitmusik (tour music) dialog on top of the v2.7.32
baseline. No data model, storage, backup, license, playback, PTT, Atmo,
waypoint/background playback, MapLibre/Explorer, or routing changes.

## Goal

Make Begleitmusik feel like an integrated **music card for the tour** instead of
a technical form, while keeping every existing capability and option.

## What changed (visual hierarchy)

The dialog body was restructured into a clear top-to-bottom hierarchy:

1. **Status/music card** (`MusicStatusCard`) — new Card in the GPS2Audio
   teal/dark style (`secondaryContainer` when enabled, `surfaceVariant` when
   off). Shows heading "Musik zur Tour", the tour name, a one-line summary
   (track/stream count or "Noch keine Musik ausgewählt"), and the enable
   `Switch` integrated on the right. Replaces the old plain "Tour: …" line +
   standalone enable row.
2. **Section "Quelle"** — compact source `FilterChip`s (Lokale Playlist /
   Stream) with leading icons (`LibraryMusic` / `Radio`, `Check` when selected).
3. **Primary action** — "Dateien hinzufügen" promoted from `OutlinedButton` to a
   filled `Button` (primary action for choosing music). "Aus Bibliothek
   auswählen" and "Playlist leeren" stay as outlined secondaries.
4. **Inviting empty state** (`MusicEmptyState`) — shown for both local and
   stream sources when nothing is selected, replacing the old technical "Noch
   keine Audiodateien…" text.
5. **Section "Verhalten & Optionen"** (`SectionLabel`) — the four behavior
   options now use plain-language titles backed by the existing enum:
   - PAUSE_RESUME → "Bei Ansagen pausieren"
   - FADE_OUT_IN → "Sanft aus- und einblenden"
   - DUCK_UNDERLAY → "Leiser im Hintergrund"
   - CONTINUE_UNDERLAY → "Weiterlaufen lassen"
   Existing descriptions, fade/duck sliders, autostart switch, and the
   preview/test controls are unchanged below this header.

The whole body keeps `verticalScroll`, and Save/Cancel remain in the
AlertDialog button slots, so it stays usable and reachable on small screens.

## Preserved capabilities (verified in code, untouched)

Enable/disable tour music, local playlist source, stream-URL source, add files,
choose from library, shuffle/random order, all four waypoint-audio behaviors,
fade duration, duck volume, autostart, stream add/edit/reorder/clear,
preview/test transport, and the unchanged `validateAndSave()` writing the exact
same `TourAudioSettings`. No new non-functional options were invented.

## No regressions to v2.7.32

The player auto-open `LaunchedEffect` (`WaypointListScreen.kt`) and the
visible-index `moveTour` fix (`WaypointViewModel.kt`) were not touched.

## Changed files

1. `app/src/main/kotlin/de/waypointaudio/ui/BegleitmusikDialog.kt`
   - New body layout; added private composables `MusicStatusCard`,
     `MusicEmptyState`, `SectionLabel`; primary-action button; plain-language
     behavior titles. Data/save logic, launchers, and `LibraryPickerDialog`
     unchanged.
2. `app/src/main/res/values/strings.xml`
   - Added strings: `music_card_heading`, `music_status_on/off`,
     `music_summary_*`, `music_choose_primary`, `music_empty_state_title/body`,
     `music_section_source`, `music_source_*_chip`, `music_section_advanced`,
     `music_behavior_short_label`, and four `music_behavior_*_plain` titles.
     No existing strings removed (a couple, e.g. `music_source_label`, are now
     unused but kept for safety).
3. `app/build.gradle.kts`
   - `versionCode 138 → 139`, `versionName 2.7.32 → 2.7.33`, changelog comment.

## Build & test

- Command: `./gradlew :app:assembleRelease --no-daemon`
- Result: **BUILD SUCCESSFUL** (~1m40s). Only pre-existing deprecation warnings
  (`Divider`, `DirectionsBike`, `AltRoute`, `menuAnchor`) — none from
  `BegleitmusikDialog.kt`.
- Signed with the release config from `keystore.properties`. Verified:
  `CN=GPS2Audio, OU=NesoHub, …`, SHA-256 `490511f3…d4e5`.
- `aapt2 badging`: `versionCode='139' versionName='2.7.33'`.
- No unit/instrumented test suite in the project. Verification was build +
  signature + version + code-path review. The dialog was **not** exercised on a
  device/emulator in this environment.

## Artifacts

- `GPS2Audio_v2.7.33_universal-release-signed.apk` — signed universal release
  APK (single APK; no ABI splits configured).
- `GPS2Audio_v2.7.33_src.zip` — clean source. Excludes `.gradle`, `.idea`,
  `.kotlin`, all `build/` dirs, and binaries (`.apk/.aab/.jks/.so` and raster
  images). The repo has no raster image resources, so nothing required was
  removed; the ZIP is complete and buildable. `keystore.properties` is excluded
  by the `.jks`/binary filters only at the file level — note the
  `keystore.properties` text file itself IS still included (it carries the
  signing path/passwords); strip it before external distribution.
