move/removeAt/undo (and the window shift) changed the current track's
position without updating lastPosition, so the next transition compared
against a stale position and consumed whatever now sat there — moving a
queued track in front of the playing one deleted the moved track on the
following skip. Added an eager-dispatcher regression test.
- deleting a track no longer bumps the layout version, so the view does
not reload and jump to the current track; the ViewModel already
updates its rows.
- layout changes (re-anchor, enqueue, consume) now reconcile positions in
place instead of calling open(), which cleared the rows and scrolled
back to the cursor.
- section headers are separate list items and reordering maps by key, so
the header no longer rides along with a dragged row (top flicker).
- disable the reorderable auto-scroll (scrollThreshold = 0). The library
scrolls past the section boundary with no valid target, then abandons
the scroll on release; without auto-scroll a drag stays put and drops
in the last reachable slot.
- keep the current track when moving a queued track before it (eager
dispatcher regression test).
- set lastPosition before seeking in jumpTo. With Dispatchers.Main
.immediate the media transition runs synchronously inside the seek, so
onPositionChanged saw the old position as an auto-advance and consumed
the track you were leaving; previous from a queued track removed it and
played the next one.
- give the up-next and context sections their own reorderable states. The
library only targets items whose key is in that state's reorderableKeys,
so a drag can no longer target a row in the other section: no more
fighting the section boundary when dragging to the top and no no-op drop
below the block.
- disable context reordering while shuffled via ReorderableItem(enabled).
- jumpTo no longer returns early on a stale current position after a
re-anchor, which could leave the player and snapshot unsynchronised.
- playNext from inside the block inserts after the entry holding the
current track, not always at index 1.
- expose a layout version in PlaybackState so the queue view reloads
when a re-anchor shifts the combined positions under it.
- removeAt recomputes the current track's combined position from the
refreshed snapshot instead of assuming a one-down shift.
- restore keeps the saved resume position when the anchor moves.
- next on the last queued track with repeat off no longer consumes it
and leaves it playing; repeat wraps instead.
- drop a redundant sort in range; revert a rejected cross-section drag
by reloading.
Re-anchor the block whenever playback lands on a different context track
(skip, previous, jump, shuffle toggle, restore), so "Up next" always
plays next instead of stranding the block behind a track the listener
has moved past. reanchorFor reports whether the anchor actually moved,
since the current track's combined position can be unchanged even when
the block shifts.
Split playback into a shuffled context and a manual up-next list.
`up_next_entries` holds the same reference-plus-range rows as the
context but is never shuffled; `playback_cursor.upNextAnchor` pins the
block between a context track and its successor. `QueueRepository`
resolves a combined position by mapping through the context order and
splicing the block after the anchor, so the controller's window and
next/previous keep working.
PlaybackController gains addToQueue/playNext, consumes a queued track
when playback advances out of it, resumes the context when the block
empties, and clears the block on a new context. The queue view gets an
editable "Up next" section and a read-only context section, and the
context menu gains Play next / Add to queue for songs, albums and
playlists.
It made no perceivable difference to the first-play hitch, so it only cost buffering
audio at launch that the user may never play. loadWindow prepares when it plays again,
and the two tests go back to their original assertions.
The tab bar was laid out before playback was known, so the restored mini player arrived
later and re-laid the whole bottom area: a couple of frames of bump, and the mini player
"loading in" after the library. SubtracksRoot now waits for PlaybackController to finish
connecting and restoring (a `ready` flag, set after restore or on disconnect) before it
composes the library, so the first library frame already includes the mini player and
nothing moves.
With playback resolved up front, the `restored` flag and its special enter/inset specs
are pointless, so they are reverted; playback the user starts animates as before.
The mini player's enter spec was decided from `firstReveal`, which was false at the first
composition (the player is not visible yet) and flipped back to `expandVertically` in the
same frame the visibility changed, so the expand animation always ran. PlaybackState now
carries `restored`, set by restore() and cleared on any user playback, and the mini
player uses it to appear in place for the whole restored session.
The first play after a restart could still pay for a fresh buffer because a stream-quality
reload rebuilds the window, and loadWindow only prepared when autoplay was set. It now
always prepares, so a reload (or the restore) leaves the current track buffered.
Restore set the window with autoplay = false and never prepared, so the first tap paid
for the connection, the first range request and the startup buffer. Prepare once the
window is set; toggling play then only starts playback.
The mini player and tab bar no longer expand or animate their inset when playback is
restored at launch, and the first artwork colour lands without a 600ms fade from the
base scheme. The last active artwork seed is persisted and read back synchronously so
the mini player can paint with it on its first frame.
beyondViewportPageCount = 1 keeps the next tab's paging flow subscribed, so Artists
replays cached data instead of showing a spinner the first time it is opened.
Flag the field that is actually blank instead of one combined "Name and address are
required", and focus it so it scrolls clear of the keyboard. The connection/save status
moves above the buttons in the ime-padded bottom bar, where the keyboard cannot hide it.
- treat flac/wav/alac as lossless and ignore the bitrate for them, so the declared length never drops below the real encoded size and truncates a lossless transcode
- read the effective stream quality once per media item and use it for both the URL and the clip, closing the window where they disagreed
- honour a bounded DataSpec length in KnownLengthDataSource and reject non-positive length fragments
- drop MetadataDurationPlayer: clipping already gives the timeline the real duration, and the forwarder could publish a wrong metadata duration for direct play
- drop the dead PlaybackState.error/lastError now that errors are toast-only, and tighten the floor test to assert the exact value
The declared upper-bound length stopped the stall where Media3 saw no seek map duration, but it also made the track look longer than the audio: the player reached the last sample still short of the declared end and waited for data that never came, so it never advanced. Clip each transcoded item to the library duration, which Media3 applies through ClippingMediaSource, so the timeline ends where the audio ends and the next track advances. The declared length still makes the stream on-demand (seekable) and never bounds reads below the real size.
Media3 treats a progressive stream as live, and ignores seeks, when neither the HTTP length nor the extractor duration is known. A transcoded response is chunked with no length and ffmpeg writes no MP3 duration header when streaming, so seeks stopped working once estimateContentLength was dropped. The server estimate is not a fix either: it under-counts (23% at mp3/24) and truncates the track.
Transcoded URLs now carry a declared upper-bound length in the fragment (never sent to the server). KnownLengthDataSource hands that length to Media3, keeping the stream seekable while never bounding reads below the real size. MetadataDurationPlayer reports the library duration to the session so the notification and UI show the true length rather than the upper bound.
The server's byte estimate can be shorter than the transcoded stream, so the player stops at Content-Length and some tracks end early. Let the server stream the true length instead.
- label the rows 'Stream quality: Wi-Fi' / 'Stream quality: Mobile'
- default mobile to 192kbps/mp3 while Wi-Fi stays unlimited/server default
- apply the selection only when Done is pressed, cancelling discards the draft
- fade the bottom of the dialog list so the remaining options are visible as scrollable
- fall back to the legacy max_bitrate/stream_format keys so existing settings survive the upgrade
- keep the last network mode when there is no active network instead of reporting mobile, so a connectivity gap does not flip modes and cause spurious reloads
- skip the quality reload when the player has ended or advanced mid-read
- keep the reload collector alive across transient failures
- edit stream quality from a local dialog draft so a fast second tap is not lost
- cover the mode mapping, migration, paused reload and equal-quality no-op with tests
Combine max bitrate and transcode format into one StreamQuality and store a separate value per network mode (Wi-Fi vs mobile data). NetworkMonitor reports metered vs unmetered via ConnectivityManager, SourceRepository selects and exposes the active quality, and PlaybackController reloads the window at the current position when it changes, so a network switch re-issues stream URLs with the new settings. Reset Coil's singleton in SubtracksApp.onCreate alongside Koin, since ArtworkSeedCache's background scope can call get() across Robolectric tests and poison the next Application.
The index to pixel arithmetic was inline and fiddly (it was missing the row gap), so pull it
out as estimateScrollPx and pin the 2-column cases. ROW_GAP is shared with the grid spacing.
heroBarColor was given the raw content scroll while HeroGradient used the image-bottom
anchor, so an opaque bar did not match the background it covered. Both now use
scrollPx - imageHeightPx. Also add the first row gap the scroll estimate was missing.
The artist background used a static gradient and a scroll-0 bar colour. It now scrolls with
the grid (fading to a dark single colour) and the bar colour comes from heroBarColor at the
real scroll, like the album/playlist hero. The gradient's scroll origin is the hero image
bottom, since the image is full-width and covers the top.
A small primary star shows next to the title on album/playlist detail song rows, the queue
and the artists tab, and in the corner of the album grid. The now playing track info stays
centred.
currentBackStack is @RestrictTo(LIBRARY_GROUP), which CI's Android Lint rejected. There is
no public API that matches a back-stack entry by its arguments, so keep it and suppress the
check rather than fall back to argument-blind popBackStack(route).
- setStar no longer treats cancellation as a rejection: rethrow CancellationException
instead of toasting/rolling back, and roll back under NonCancellable on a real failure
- serialise setStar so overlapping toggles cannot clobber each other's rollback
- the menu star item reverts its label when the request fails (setStar now returns the
result), so the open menu cannot drift from the row
- ContextMenuHost.dismiss clears the actions so a popped screen's ViewModel is released
- one shared setStar from the app shell instead of five per-ViewModel copies
- extract the nav-focus decision into focusPops and unit-test it
- navigateDetail scans the whole back stack and pops back to a matching album/artist/
playlist, not just the top, so artist -> album -> now playing -> view artist focuses the
existing artist instead of pushing a second one
- raise the sheet container to surfaceContainerHigh so it reads against the background
behind it
- menu actions run before the sheet collapses, so tapping an album/artist navigates
immediately instead of waiting for the dismiss; the sheet still animates closed
- host the sheet in the app shell so it survives the navigation it triggers
- now playing fades out (rather than sliding) when its menu navigates to an album/artist,
and navigates first
- navigating to a detail screen already on top of the stack focuses it instead of pushing
a duplicate
- drop the drag handle from both sheets, even the menu header's left/top margins, and add
a bottom margin
- star/unstar updates the local row immediately and rolls back with a toast if the server
rejects it, instead of waiting on the response
- the menu collapses with an animation on dismiss
- star/unstar keeps the menu open and toggles its item in place
- the album/artist rows show the target's name instead of "View album"/"View artist"
- the menu header shows the cover art thumbnail
Album, artist and playlist detail screens get a more button plus long-press on their song
and album rows; now playing gets a more button for the current song. Song menus can reach
the album and artist and star; the now-playing song is read from Room so its star state is
current.
Star is a new write path: MusicSource.setStar posts star.view/unstar.view and
LibraryRepository updates the local row on success (toast on failure). Long-press an
album, artist, song or playlist in the library to open a bottom sheet with play/shuffle,
star/unstar and view-album/view-artist.
The title effect was keyed on both the queue context and the per-track fallback
(album name), so advancing a track reset the resolved playlist/album name to the
album fallback until the async lookup returned. Key only on the queue context;
`remember(queueContext)` already resets it synchronously when the context changes.
- scope QueueViewModel to the queue overlay so its rows are released on close
and a reopened queue cannot show two overlapping lists; key open() on the
overlay visibility so a fast reopen still rescans and refocuses
- reuse row ids by song identity when a window (re)loads so Compose does not
cross-fade the old rows out while the new ones fade in
- fade the artist name scrim in and key its busy check on the thumbnail, the
same ref the theme already uses, so a cached seed shows it immediately
- start detail gradients from the neutral base artwork until the seed resolves
instead of inheriting the now playing theme and snapping to the artist colours
- fade the now playing and detail status bar scrims by putting the graphicsLayer
before statusBarScrim(), which otherwise drew the background outside the layer
- decode full-size and hero covers with FilterQuality.High to stop the moire
during overscroll stretch
