  • slide left to cancel recording.
• Added minimum voice length validation (>= 1s) before sending.
• Integrated voice message sending via existing media upload path (audio/mp4 attachment).
• Added process-wide audio focus coordinator to enforce single active audio source:
  • attachment player pauses when another source starts,
  • recording requests focus and stops competing playback.

  • voice record button semantic label for TalkBack.

Step 69 - Bugfix pass: voice recording, theme apply, profile avatar UX

• Fixed voice recording start on Android by switching VoiceRecorder to compatible MediaRecorder() initialization.
• Fixed microphone permission flow: record action now triggers runtime permission request reliably and auto-starts recording after grant.
• Fixed theme switching application by introducing app-level MessengerTheme and switching app manifest base theme to DayNight.
• Fixed profile screen usability after avatar upload:
  • enabled vertical scrolling with safe insets/navigation padding,
  • constrained avatar preview to a centered circular area instead of full-screen takeover.

• Kept phone layout unchanged while centering content and limiting line width on larger displays.
• Fixed voice hold-to-send gesture reliability by removing pointer-input restarts during active recording, so release consistently triggers send path.

Step 73 - Voice message send/playback bugfixes

• Fixed voice media type mapping in message repository: recorded files with voice_*.m4a are now sent as message type voice (not generic audio).
• Fixed audio replay behavior: when playback reaches the end, next play restarts from 0:00.
• Improved duration display in audio/voice player by adding metadata fallback when MediaPlayer duration is not immediately available.

Step 74 - UI references consolidation (Batch 4)

• Added full Telegram reference mapping checklist (docs/android-ui-batch-4-checklist.md) with screenshot-by-screenshot description.
• Added explicit icon policy: no emoji icons in production UI components, Material Icons/vector icons only.
• Updated UI checklist index with Batch 4 entry.

Step 75 - Material Icons migration (Batch 1 start)

• Replaced symbol/emoji-based UI controls in chat surfaces with Material Icons:
  • chat header/menu/search controls (more, up/down),

  • multi-select markers (radio checked/unchecked, selected check),
  • attachment/media markers (movie, attach file).
• Replaced chat list management FAB glyph toggle (+/×) with Material Add/Close icons.
• Added androidx.compose.material:material-icons-extended dependency for consistent icon usage.

Step 76 - Shared main tabs shell with scroll-aware visibility

• Added dedicated Contacts page route and wired it into main tabs.
• Removed local duplicated bottom panel from chat list screen.
• Implemented scroll-direction behavior for all 4 main pages:
  • hide panel on downward scroll,
  • show panel on upward scroll / at top.

Step 77 - Main tabs bar UX/layout fix

• Replaced custom pill-row main bar with compact NavigationBar inside rounded container for stable 4-tab layout on small screens.
• Added bottom content paddings for Chats/Contacts/Settings/Profile pages so content is not obscured by the floating main bar.
• Raised chats management FAB offset to avoid overlap with the global bottom bar.

Step 78 - Telegram-like bottom tabs visual tuning

• Tuned shared main bar visual style to better match Telegram references:
  • rounded floating container with subtle elevation,

• Moved chats management toggle action into chats app bar.
• Kept safe-area handling and bottom insets consistent with shared floating tabs bar to avoid overlap.

Step 80 - Top bar offset consistency fix

• Unified top bar alignment across Chats, Contacts, Settings, and Profile:
  • removed extra outer paddings that shifted headers down/right on some pages,
  • separated content padding from top app bar container.
• Result: consistent title baseline and horizontal alignment between main pages.

Step 81 - Chats bottom gap fix when tabs bar hidden

• Fixed blank gap at the bottom of chats list when global tabs bar auto-hides on scroll.

Step 82 - Chats list header closer to Telegram reference

• Removed Archived top tab from chats list UI.
• Added search action in top app bar and unified single search field with leading search icon.
• Kept archive as dedicated row inside chats list; opening archive now happens from that row and back navigation appears in app bar while archive is active.

Step 83 - Chats header realtime connection status

• Added realtime connection state stream (Disconnected/Connecting/Reconnecting/Connected) to RealtimeManager.
• Wired websocket lifecycle into that state in WsRealtimeManager.
• Bound chats top bar title to realtime state:
  • shows Connecting... while reconnect/initial connect is in progress,
  • shows regular page title once connected.

Step 84 - Chats list preview icon policy cleanup

• Updated chat last-message preview text to remove emoji prefixes.
• Switched media-type preview prefixes to plain text labels (Photo, Video, Voice, etc.) to match Material-icons-only UI policy.

Step 85 - Unread counter fix for active/read chats

• Added ChatDao.markChatRead(chatId) to clear unread_count and unread_mentions_count in Room.
• Applied optimistic local unread reset on markMessageRead(...) in message repository.
• Fixed realtime unread logic: incoming messages in currently active chat no longer increment unread badge.

Step 86 - Chats list visual pass toward Telegram reference

• Updated chats list row density: tighter vertical rhythm, larger avatar, stronger title hierarchy, cleaner secondary text.
• Restyled archive as dedicated list row with leading archive icon avatar, subtitle, and unread badge.
• Kept search in top app bar action and changed search field default to collapsed (opens via search icon).
• Returned message-type emoji markers in chat previews:
  • 🖼 photo, 🎤 voice, 🎵 audio, 🎥 video, ⭕ circle video, 🔗 links.

Step 87 - Chats list micro-typography and time formatting

• Refined chat row typography hierarchy to be closer to Telegram density:
  • title/body/presence font scale aligned and single-line ellipsis for long values.
• Tightened unread/mention badge sizing and spacing for compact right-side metadata.
• Updated trailing time formatter:
  • today: HH:mm,
  • this week: localized short weekday,
  • older: dd.MM.yy.

Step 88 - Chats list interaction states (menu/select/search)

• Added default overflow menu (⋮) state in chats header with Telegram-like quick actions UI.
• Added long-press multi-select mode for chat rows with:
  • top selection bar (count, action icons),
  • dedicated overflow menu for selected chats.
• Added dedicated search-mode state in chats screen:
  • search field + section chips (Chats/Channels/Apps/Posts),
  • horizontal recent avatars strip,
  • list filtered by active query.

Step 89 - Chats actions wiring + duplicate menu fix

• Removed duplicated overflow action in chats top bar (single ⋮ remains in default mode).
• Wired selection actions to behavior:
  • delete selected -> leave selected chats,
  • archive selected -> switch to archived section,
  • non-implemented bulk actions now show explicit user feedback.
• Wired default menu actions:
  • create group/channel -> open management panel,
  • saved -> open saved chat if present,
  • unsupported items show clear feedback instead of silent no-op.

Step 90 - Fullscreen chats search redesign (Telegram-like)

• Reworked chats search mode into a fullscreen flow:
  • top rounded search field with inline clear button,
  • horizontal category chips (Chats, Channels, Apps, Posts),
  • dedicated recent avatars row for the active category.
• Added search-mode content states:
  • empty query -> Recent list block (history-style chat rows),
  • non-empty query -> local matches + Global search and Messages sections.
• Kept search action in chats top bar; while search mode is active, app bar switches to back-navigation + empty title (content drives the page).

Step 91 - Search history/recent persistence + clear action

• Added ChatSearchRepository abstraction and DataStoreChatSearchRepository implementation.
• Persisted chats search metadata in DataStore:
  • recent opened chats list,
  • search history list (bounded).
• Wired chats fullscreen search to persisted data:
  • green recent avatars strip now reads saved recent chats,
  • red Recent list now reads saved history with fallback.
• Connected Очистить action to real history cleanup in DataStore.
• On opening a chat from search results/messages/history, the chat is now stored in recent/history.

Step 92 - Search filter leak fix on exit

• Fixed chats search state leak: leaving fullscreen search now resets local/global query.
• Main chats list no longer stays filtered by previous search input after returning from search mode.

Step 93 - Fullscreen search UX polish

• Added system back-handler for search mode with safe query reset.
• Improved fullscreen search result sections:
  • Показать больше / Свернуть toggle for global users,
  • Показать больше / Свернуть toggle for message results.
• Added explicit empty-state text when local/global/message search sections all have no results.

Step 94 - Pinned-only drag markers in selection mode

• Updated chats multi-select row UI: drag markers are now shown only for pinned chats.
• Non-pinned chats no longer render reorder marker in selection mode.

Step 95 - Selection badge on avatar (Telegram-like)

• Added explicit selection indicator directly on chat avatars in multi-select mode:
  • selected chat -> colored circle with check icon,
  • unselected chat -> empty outlined circle.
• This matches the reference behavior and makes selected rows easier to scan.

Step 96 - Selection menu labels and behavior polish

• Updated multi-select top actions/menu to be closer to Telegram reference in wording.
• Added dynamic Закрепить/Открепить label in selection overflow based on selected chats pinned state.
• Kept non-supported actions explicit with user feedback (Toast), avoiding silent no-op behavior.

Step 97 - Chats popup/select actions wired to backend API

• Extended Android chat data layer with missing parity endpoints:
  • archive/unarchive
  • pin-chat/unpin-chat
  • clear
  • delete (for_all=false)
  • chat notifications get/update
• Added repository methods and ViewModel actions for those operations.
• Replaced chats multi-select UI stubs with real API calls:
  • mute/unmute selected chats,
  • archive/unarchive selected chats,
  • pin/unpin selected chats,
  • clear selected chats,
  • delete selected chats for current user.

Step 98 - Realtime sync fix for pin/archive updates

• Improved chat_updated handling in realtime flow:
  • now refreshes both active and archived chats lists to sync user-scoped flags (pinned, archived) immediately.
• Added parser fallback for realtime chat events to support payloads with either chat_id or id.

Step 99 - Saved chat API parity

• Added Android support for GET /api/v1/chats/saved.
• Wired chats overflow Saved action to real backend request (instead of local title heuristic).
• Saved chat is now upserted into local Room cache and opened via normal navigation flow.

Step 100 - Android image compression before upload

• Added pre-upload image compression in Android media pipeline (NetworkMediaRepository).
• For non-GIF images:
  • decode + resize with max side 1920,
  • re-encode as image/jpeg with quality 82,
  • keep original bytes if compression does not reduce payload size.
• Upload request and attachment metadata now use actual prepared payload (fileName, fileType, fileSize), matching web behavior.

Step 101 - Chat title/profile API parity

• Added Android API integration for:
  • PATCH /api/v1/chats/{chat_id}/title
  • PATCH /api/v1/chats/{chat_id}/profile
• Extended ChatRepository/NetworkChatRepository with updateChatTitle(...) and updateChatProfile(...).
• Wired these actions into the existing Chat Management panel:
  • edit selected chat title,
  • edit selected chat profile fields (title/description).

Step 102 - Global search + message thread parity

• Added Android data-layer integration for unified backend global search:
  • GET /api/v1/search
  • new SearchRepository + SearchApiService returning users/chats/messages.
• Switched chats fullscreen search flow to use unified backend search instead of composed per-domain calls.
• Extended message data layer with:
  • GET /api/v1/messages/{message_id}/thread
  • MessageRepository.getMessageThread(...) for thread/replies usage in upcoming UI steps.

Step 103 - Contacts API parity + real Contacts screen

• Added Android integration for contacts endpoints:
  • GET /api/v1/users/contacts
  • POST /api/v1/users/{user_id}/contacts
  • POST /api/v1/users/contacts/by-email
  • DELETE /api/v1/users/{user_id}/contacts
• Extended AccountRepository + NetworkAccountRepository with contacts methods.
• Replaced placeholder Contacts screen with real stateful flow (ContactsViewModel):
  • load contacts from backend,
  • user search + add contact,
  • add contact by email,
  • remove contact,
  • loading/refresh/error/info states.

Step 104 - Push token sync (Android + backend)

• Added backend push token lifecycle API and storage:
  • POST /api/v1/notifications/push-token
  • DELETE /api/v1/notifications/push-token
  • new table push_device_tokens (+ Alembic migration 0027_push_device_tokens).
• Added Android push token sync manager:
  • registers FCM token on app start and after auth refresh/login,
  • updates backend token on FirebaseMessagingService.onNewToken,
  • unregisters token on logout.
• Added backend FCM delivery in Celery notification tasks:
  • sends to registered user device tokens,
  • auto-removes invalid/unregistered tokens,
  • safe fallback logs when Firebase is not configured.

Step 105 - Web Firebase push registration

• Added web-side Firebase Messaging bootstrap (env-driven, no hardcoded secrets):
  • fetch web push token and register in backend via /notifications/push-token,
  • unregister token on logout,
  • handle foreground push payload via existing notification service worker.
• Added required env keys to web/.env.example and backend Firebase env keys to root .env.example.

Step 106 - Unread counter stabilization in Chat screen

• Fixed read acknowledgement strategy in ChatViewModel:
  • read status is now acknowledged by the latest visible message id in chat (not only latest incoming),
  • delivery status still uses latest incoming message.
• This removes cases where unread badge reappears after chat list refresh because the previous read ack used an outdated incoming id.

Step 107 - Read-on-visible + cross-device unread sync

• Implemented read acknowledgement from actual visible messages in ChatScreen:
  • tracks visible LazyColumn rows and sends read up to max visible incoming message id.
  • unread now drops as messages appear on screen while scrolling.
• Improved cross-device sync (web <-> android):
  • message_read realtime event now parses user_id and last_read_message_id.
  • on message_read, Android refreshes chat snapshot from backend to keep unread counters aligned across devices.

Step 108 - Strict read boundary by visible incoming only

• Removed fallback read-pointer advancement in ChatViewModel.acknowledgeLatestMessages(...) that previously moved lastReadMessageId by latest loaded message id.
• Read pointer is now advanced only via onVisibleIncomingMessageId(...) from visible incoming rows in ChatScreen.
• This prevents read acknowledgements from overshooting beyond what user actually saw during refresh/recompose scenarios.

Step 109 - Telegram-like Settings/Profile visual refresh

• Redesigned SettingsScreen to Telegram-inspired dark card layout:
  • profile header card with avatar/name/email/username,
  • grouped settings rows with material icons,
  • appearance controls (Light/Dark/System),
  • quick security/help sections and preserved logout/back actions.
• Redesigned ProfileScreen to Telegram-inspired structure:
  • gradient hero header with centered avatar, status, and action buttons,
  • primary profile info card,
  • tab-like section (Posts/Archived/Gifts) with placeholder content,
  • inline edit card (name/username/bio/avatar URL) with existing save/upload behavior preserved.

Step 110 - Multi-account foundation (switch active account)

• Extended TokenRepository to support account list and active-account switching:
  • observe/list stored accounts,
  • get active account id,
  • switch/remove account,
  • clear all tokens.
• Reworked EncryptedPrefsTokenRepository storage model:
  • stores tokens per userId and account metadata list in encrypted prefs,
  • migrates legacy single-account keys on first run,
  • preserves active account pointer.
• NetworkAuthRepository now upserts account metadata after auth/me calls.
• Added Settings UI account section:
  • shows saved accounts,
  • allows switch/remove,
  • triggers auth recheck + chats reload on switch.

Step 111 - Real Settings + persistent theme + add-account UX

• Implemented persistent app theme storage via DataStore (ThemeRepository) and applied theme mode on app start in MainActivity.
• Reworked SettingsScreen to contain only working settings and actions:
  • multi-account list (Switch/Remove) + Add account dialog with email/password sign-in,
  • appearance (Light/Dark/System) wired to persisted theme,
  • notifications (global + preview) wired to NotificationSettingsRepository,
  • privacy update, blocked users management, sessions revoke/revoke-all, 2FA controls.
• Updated ProfileScreen to follow current app theme colors instead of forced dark palette.

Step 112 - Settings cleanup (privacy dropdowns + removed extra blocks)

• Replaced free-text privacy inputs with dropdown selectors (everyone, contacts, nobody) for:
  • private messages,
  • last seen,
  • avatar visibility,
  • group invites.
• Removed direct block by user id controls from Settings UI as requested.
• Removed extra bottom Settings actions (Profile row and Back to chats button) and kept categorized section layout.

Step 113 - Auth flow redesign (email -> password/register -> 2FA) + startup no-flicker

• Added step-based auth domain/use-cases for:
  • GET /api/v1/auth/check-email
  • POST /api/v1/auth/register
  • login with optional otp_code / recovery_code.
• Updated Android login UI to multi-step flow:
  • step 1: email input,
  • step 2: password for existing account or register form (name, username, password) for new account,
  • step 3: 2FA OTP/recovery code when backend requires it.
• Improved login error mapping for 2FA-required responses, so app switches to OTP step instead of generic invalid-password message.
• Removed auth screen flash on startup:
  • introduced dedicated startup route with session-check loader,
  • delayed auth/chats navigation until session check is finished.
• Added safe fallback in MainActivity theme bootstrap to prevent crash if ThemeRepository injection is unexpectedly unavailable during startup.

Step 114 - Multi-account switch sync fix (chats + realtime)

• Fixed account switch flow to fully rebind app data context:
  • restart realtime socket on new active account token,
  • force refresh chats for both archived=false and archived=true right after switch.
• Fixed navigation behavior on account switch to avoid noisy popBackStack ... not found and stale restored stack state.

Step 115 - Settings UI restructured into Telegram-like folders

• Reworked Settings into a menu-first screen with Telegram-style grouped rows.
• Added per-item folder pages (subscreens) for:
  • Account
  • Chat settings
  • Privacy
  • Notifications
  • Devices
  • Data/Chat folders/Power/Language placeholders
• Kept theme logic intact and moved appearance controls into Chat settings folder.

Step 116 - Profile cleanup (remove non-working extras)

• Removed non-functional profile tabs and placeholder blocks:
  • Posts
  • Archived
  • Gifts
• Removed Settings hero button from profile header.
• Removed bottom Back to chats button from profile screen.
• Simplified profile layout so the editable profile form is the primary secondary section toggled by Edit.
• Updated ProfileRoute navigation contract to match the simplified screen API.

Step 117 - Settings folders cleanup (remove back button action)

• Removed Back to chats button from all Settings folder pages.
• Simplified Settings navigation contract by removing unused onBackToChats parameter from:
  • SettingsRoute
  • SettingsScreen
  • SettingsFolderView
• Updated AppNavGraph Settings destination call-site accordingly.

Step 118 - Android push notifications grouped by chat

• Reworked NotificationDispatcher to aggregate incoming messages into one notification per chat:
  • stable notification id per chatId,
  • per-chat unread counter,
  • multi-line inbox preview of recent messages.
• Added app-level summary notification that groups all active chat notifications.
• Added deduplication guard for repeated push deliveries of the same messageId.
• Added notification cleanup on chat open:
  • when push-open intent targets a chat in MainActivity,
  • when ChatViewModel enters a chat directly from app UI.

Step 119 - Chat screen visual baseline (Telegram-like start)

• Reworked chat top bar:
  • icon back button instead of text button,
  • cleaner title/subtitle styling,
  • dedicated search icon in top bar (inline search is now collapsible).
• Updated pinned message strip:
  • cleaner card styling,
  • close icon action instead of full text button.
• Updated composer baseline:
  • icon-based emoji/attach/send/mic controls,
  • cleaner container styling closer to Telegram-like bottom bar.

Step 120 - Message bubble layout pass (Telegram-like geometry)

• Reworked MessageBubble structure and density:
  • cleaner outgoing/incoming bubble geometry,
  • improved max width and alignment behavior,
  • tighter paddings and spacing for mobile density.
• Redesigned forwarded/reply blocks:
  • compact forwarded caption styling,
  • reply block with accent stripe and nested preview text.
• Improved message meta line:
  • cleaner time + status line placement and contrast.
• Refined reactions and attachments rendering inside bubbles:
  • chip-like reaction containers,
  • rounded image/file/media surfaces closer to Telegram-like visual rhythm.

Step 121 - Chat selection and message action UX cleanup

• Added Telegram-like multi-select top bar in chat:
  • close selection,
  • selected counter,
  • quick forward/delete actions.
• Simplified tap action menu flow for single message:
  • richer reaction row (❤️ 👍 👎 🔥 🥰 👏 😁),
  • reply/edit/forward/delete actions kept in one sheet.
• Removed duplicate/conflicting selection controls between top and bottom action rows.

Step 122 - Chat 3-dot menu + chat info media tabs shell

• Added chat header 3-dot popup menu with Telegram-like actions:
  • Chat info
  • Search
  • Notifications
  • Change wallpaper
  • Clear history
• Added Chat info bottom sheet with tabbed sections:
  • Media
  • Files
  • Links
  • Voice
• Implemented local tab content from current loaded chat messages/attachments to provide immediate media/files/links/voice overview.

Step 123 - Chat info visual pass (Telegram-like density)

• Updated Chat info tabs to pill-style horizontal chips with tighter Telegram-like spacing.
• Improved tab content rendering:
  • Media now uses a 3-column thumbnail grid.
  • Files / Links / Voice use denser card rows with icon+meta layout.
  • Voice rows now show a dedicated play affordance.
• Refined menu order in chat 3-dot popup and kept actions consistent with current no-calls scope.

Step 124 - Inline search close fix + message menu visual pass

• Fixed inline chat search UX:

  • closing search now also clears active query/filter without re-entering chat.
• Added automatic inline-search collapse when entering multi-select mode.
• Reworked message tap action sheet to Telegram-like list actions with icons and clearer destructive Delete row styling.

Step 125 - Chat header/top strips visual refinement

• Refined chat header density and typography to be closer to Telegram-like proportions.
• Updated pinned strip visual:
  • accent vertical marker,
  • tighter spacing,
  • cleaner title/content hierarchy.
• Added top mini audio strip under pinned area:
  • shows latest audio/voice context from loaded chat,
  • includes play affordance, speed badge, and dismiss action.

Step 126 - Message bubble/composer micro-polish

• Updated message bubble sizing and density:
  • reduced bubble width for cleaner conversation rhythm,
  • tighter vertical spacing,
  • text style adjusted for better readability.
• Refined bottom composer visuals:
  • switched to Telegram-like rounded input container look,
  • emoji/attach/send buttons now use circular tinted surfaces,
  • text input moved to filled style with hidden indicator lines.

Step 127 - Top audio strip behavior fix (playback-driven)

• Reworked top audio strip logic to be playback-driven instead of always-on:
  • strip appears only when user starts audio/voice playback,
  • strip switches to the currently playing file,
  • strip auto-hides when playback stops.
• Added close (X) behavior that hides the strip and force-stops the currently playing source.

Step 128 - Parity docs update: text formatting gap

• Synced Android parity documentation with web-core status:
  • added explicit Text formatting parity gap to docs/android-checklist.md,
  • added dedicated Android gap block in docs/backend-web-android-parity.md for formatting parity.
• Marked formatting parity as part of highest-priority Android parity block.

Step 129 - Parity block (1/3/4/5/6): formatting, notifications inbox, resend verification, push sync

• Completed Android text formatting parity in chat:
  • composer toolbar actions for bold/italic/underline/strikethrough,
  • spoiler, inline code, code block, quote, link insertion,
  • message bubble rich renderer for web-style markdown tokens and clickable links.
• Added server notifications inbox flow in account/settings:
  • API wiring for GET /api/v1/notifications,
  • domain mapping and recent-notifications UI section.
• Added resend verification support on Android:
  • API wiring for POST /api/v1/auth/resend-verification,
  • Verify Email screen action for resending link by email.
• Hardened push token lifecycle sync:
  • token registration dedupe by (userId, token),
  • marker cleanup on logout,
  • best-effort re-sync after account switch.
• Notification delivery polish (foundation):
  • foreground notification body now respects preview setting and falls back to media-type labels when previews are disabled.
• Verified with successful :app:compileDebugKotlin and :app:assembleDebug.

Step 130 - Chat UX pack: video viewer, emoji/GIF/sticker picker, day separators

• Added chat timeline day separators with Telegram-like chips:
  • Сегодня, Вчера, or localized date labels.
• Added fullscreen video viewer:
  • video attachments now open in a fullscreen overlay with close action.
• Added composer media picker sheet:
  • tabs: Эмодзи, GIF, Стикеры,
  • emoji insertion at cursor,
  • remote GIF/sticker selection with download+send flow.
• Extended media type mapping in message send pipeline:
  • GIFs now sent as gif,
  • sticker-like payloads sent as sticker (filename/mime detection).
• Added missing fallback resource theme declarations (themes.xml) to stabilize clean debug assembly on local builds.

Step 131 - Channel chat Telegram-like visual alignment

• Added channel-aware chat rendering path:
  • MessageUiState now carries chatType from ChatViewModel,
  • channel timeline bubbles are rendered as wider post-like cards (left-aligned feed style).
• Refined channel message status presentation:
  • post cards now show cleaner timestamp-only footer instead of direct-message style checks.
• Added dedicated read-only channel bottom bar (for non owner/admin):
  • compact Telegram-like controls with search + centered Включить звук action + notifications icon.
• Kept existing full composer for roles allowed to post in channels (owner/admin).

Step 132 - Voice recording composer overlap fix

• Fixed composer overlap during voice recording:
  • recording status/hint is now rendered in a dedicated top block inside composer,
  • formatting toolbar is hidden while recording is active.
• Prevented controls collision for locked-recording actions:
  • Cancel/Send now render on a separate row in locked state.

Step 133 - Video/audio player controls upgrade

• Upgraded fullscreen video viewer controls:
  • play/pause button,
  • seek slider (scrubbing),
  • current time / total duration labels.
• Upgraded attachment audio player behavior (voice + audio):
  • added seek slider for manual rewind/fast-forward,
  • unified speed toggle for both voice and audio playback.

Step 134 - Hilt startup crash fix (MessengerApplication_GeneratedInjector)

• Fixed startup crash:
  • NoClassDefFoundError: MessengerApplication_GeneratedInjector.
• Root cause observed in build pipeline:
  • MessengerApplication_GeneratedInjector.class existed after javac,
  • but was missing in transformDebugClassesWithAsm/dirs before dexing.
• Added Gradle backfill task for debug/release variants:
  • copies *Application_GeneratedInjector.class from intermediates/javac/.../classes into intermediates/classes/.../transform...ClassesWithAsm/dirs if missing,
  • wired task as dependency of dexBuilder<Variant>.
