feat(settings): add a Widgets page with live previews and add to home screen - #1249
Widget options sat at the bottom of Theme & colors, and the Your Shows cover style had no setting.
There was no way to see boxlore's widgets, or add one, from inside the app.
The widget picker still showed the previous widget design.
What changed
Widgets (:feature:widgets)
WidgetPickerPreviews builds each preview from the live renderer with sample content and publishes it through AppWidgetManager.setWidgetPreview on Android 15 and later, again whenever the widget colours, lettering or cover style change. The first publish after a launch waits for the startup work gate.
The six static widget_preview_*.xml layouts are redrawn in the new shapes for older versions. Their sample covers are cut round or rounded inside the vector itself, so the cut shows wherever a preview is drawn.
HomeScreenWidgets lists the widgets for the app: picker names, the live preview and its size, whether the home screen app adds a widget on request (canAdd) and the request (requestAdd).
LibraryWidgetRenderer and LibraryWidgetRemoteViewsFactory accept rows a preview carries with it, since a preview cannot bind the list service.
Settings and app (:feature:settings, :app)
New AppearanceWidgetsPage, reached from a Widgets row on Appearance. The widget colour choice moves there from Theme & colors.
Each widget is a card: its real look through the AppearanceWidgetPreview slot, its name and description, and an Add button. HomeScreenWidgetPreview in :app lays the widget out at its own size inside a widget host and scales that picture to fit, so it looks the same at every width. The two round players share a row.
The cover choice (WidgetShowsArtwork) sits in the Your Shows card, and the preview redraws when it changes.
The home screen app answers an add request by opening its confirmation, or by adding the widget and reporting it through the request's success callback (WidgetAddedReceiver, HomeScreenWidgets.added). When neither happens shortly after the latest request, that card offers help and links to the app's permission settings; the help goes away if an answer arrives later. When the home screen app cannot add widgets at all, the cards stay without buttons, with the steps for adding one by hand.
Previews never pass a touch to the widget inside them, and screen readers skip them.
Behavior & compatibility
The widget colour setting keeps its stored value; only its place in Settings changes.
New SharedPreferences file boxlore_widget_picker_previews records the look each published preview was drawn for.
Before Android 15 nothing is published and the static previews are used.
No server, API or notification payload changes.
Listener impact
Settings › Appearance › Widgets shows every boxlore widget as it looks on the home screen.
Tapping Add puts a widget on the home screen, on phones and home screen apps that allow it. Where a phone blocks it, the page says how to allow it or add the widget by hand.
Listeners can choose whole covers or shapes for the Your Shows widget and see the result at once.
The widget picker shows the new widget look, in the listener's own widget colours on Android 15 and later.
Release copy
Added
Appearance › Widgets page (AppearanceWidgetsPage): widget colours, a card per widget with a live preview (AppearanceWidgetPreview, HomeScreenWidgetPreview) and an Add to home screen request (HomeScreenWidgets.requestAdd), and the Your Shows cover choice (WidgetShowsArtwork).
WidgetPickerPreviews: generated widget picker previews on Android 15 and later.
HomeScreenWidgets: the widgets' picker names, live previews and add requests for the app.
Changed
Static widget picker previews are redrawn in the new widget shapes, with the cover cuts baked into the sample cover vectors.
The widget colour choice moves from Theme & colors to Appearance › Widgets.
./gradlew detekt, ktlintCheck and lintDebug for the widgets and settings modules
Adaptive coverage: the Widgets page is tested at phone width and at 1280 dp, where previews stay at their real size and are never enlarged (AppearanceWidgetsPageTest); previews are laid out at their own size and scaled into smaller frames (HomeScreenWidgetPreviewTest).
Renders of the live and static picker previews (WidgetRenderGalleryTest) and of the in-app previews (HomeScreenWidgetPreviewTest), saved with BOXLORE_WIDGET_RENDERS=1, were reviewed.
Device
Add to home screen on a home screen app that accepts the request
Add to home screen on a phone that blocks the request: the card offers help and opens the app's permissions
Widget picker previews on Android 15 or later and on an older version

Browse and preview available home-screen widgets in Settings › Appearance › Widgets, then request to add them directly to your home screen.
Choose widget colors and select whether Your Shows artwork uses whole covers or shapes.
See updated widget previews in the system picker on supported Android versions.
If adding a widget isn’t available or a request goes unanswered, Settings provides guidance and an app-settings shortcut.
The change adds a Widgets page under Appearance settings. It lists available home-screen widgets, displays widget previews, and provides add requests. The widget module adds a registry and Android 15+ live picker previews, while the app adds in-settings widget rendering and appearance controls.
The widget module adds a six-entry registry with preview metadata and add-request functions. Android 15+ picker previews use sample content and refresh when appearance preferences change. Static previews and related assets are updated.
The app renders registered widgets at their configured size and scales them to fit the preview area. Navigation passes widget appearance settings and available widgets to the preview. Tests cover sizing, touch handling, accessibility, and widget listing.
Widgets appearance page and add flow feature/settings/src/main/java/..., feature/settings/src/test/java/..., feature/settings/README.md, release-notes/upcoming.md
Appearance settings adds widget color and cover-style controls, widget preview cards, add requests, and guidance for unavailable or unanswered requests. The new page is wired into navigation and preference state, with related analytics, tests, documentation, and release notes.

Merge Risk: Low · up to 09fba
The new Widgets page works as described, but a few edge cases need cleanup. A stale "your phone didn't let boxlore add it" message can appear on the wrong card. A truncated sample cover could leave placeholder previews. Preview publishing at startup could add minor startup cost. These are bounded and can be fixed before or shortly after merge.

Resolution
Add hermetic JVM tests for accepted previews, skipping unchanged previews, republishing changed previews, and retrying rejected or failed publications.

- Around line 74-75: Update the initial call to WidgetPickerPreviews.refresh in
the widget installer so its first publish runs through StartupWorkGate on
Android 15 and later. Preserve subsequent preference-triggered preview
refreshes, ensuring only the initial publish is gated.

- Around line 173-183: Update the request lambda to retain the Job for the
pending unanswered check and cancel it whenever a new add request starts, before
launching the new delay. Keep the existing ADD_WIDGET_ANSWER_MS delay and
unansweredKey logic so only the latest request can mark a widget unanswered.
- Around line 168-172: Update the widget request flow in AppearanceWidgetsPage
so the widget-created success callback clears the warning, including when
confirmation arrives after the existing delay. Do not report failure solely
because ON_PAUSE was not observed; preserve any existing handling for confirmed
outcomes.

- Around line 201-210: Update sampleCover to write the PNG to a temporary file
in the same directory, then rename it to the stable final path only after
writing completes. Clean up the temporary file on failure, and return the final
path only when this write succeeds or a concurrent writer has already produced
the final file.
