Subscribe all bookmark and pinned note IDs to the EventFinderFilterAssembler
when the bookmark screen opens, so events are fetched in bulk via a single
REQ rather than loading one-by-one as the user scrolls.
Applied to both BookmarkListScreen (new bookmarks + pinned notes) and
OldBookmarkListScreen (legacy bookmarks).

Call screen elements were too close to the screen edges because they
didn't account for status bar and navigation bar insets. Apply
WindowInsets.statusBars and WindowInsets.navigationBars padding to
all call screen layouts while keeping video backgrounds full-bleed.

Videos with extreme aspect ratios (e.g. very tall or very wide) cause
an IllegalArgumentException when entering PiP mode because Android
requires the ratio to be between ~0.4184 and 2.39. Clamp the ratio
before passing it to setAspectRatio.
https://claude.ai/code/session_018uqcACcXpLQxwzVFhePisJ
When the app is alive but backgrounded, the relay subscription delivers
the call event first, marking it as consumed. The push notification
path then skips showing the notification because the event is already
consumed. This left the phone ringing with no notification and no way
to bring the app to the foreground.
Now CallController shows the call notification directly when entering
IncomingCall state, regardless of how the event was received. The
notification's fullScreenIntent brings the app to the foreground.

AudioManager.isSpeakerphoneOn is deprecated since API 31 and silently
ignored on modern devices. Switch to setCommunicationDevice() which
properly routes call audio to speaker, earpiece, or Bluetooth on
Android 12+, with fallback to the legacy API on older versions.

Our own renegotiation answers can echo back through the relay and
get processed as if from the peer. Check that the peer connection
is in HAVE_LOCAL_OFFER state before applying a remote answer SDP,
preventing the "Called in wrong state: stable" error.
https://claude.ai/code/session_014espsysob7MrE8X8e75jFX
Uses the proximity sensor to detect when the phone is held to the ear
and automatically pauses the camera/video track. Video resumes when the
phone is moved away, but only if the user had video enabled.

Change default port from 19050 to 17392 to avoid conflicts with other
Tor-using apps. When binding fails (address in use), increment the port
and retry up to 10 times before giving up.

When a user is logged in on multiple devices, all devices ring on an
incoming call. Previously, accepting or rejecting on one device left the
others still ringing.
Now, acceptCall() and rejectCall() also publish a self-addressed
gift-wrapped event (to the user's own pubkey) so other devices receive
it and transition out of the IncomingCall state. Added ANSWERED_ELSEWHERE
end reason and handling in onCallAnswered/onCallRejected for IncomingCall
state.
https://claude.ai/code/session_01X9juzyPYWqxRMCgDWEw8R1
When toggling video mid-call, addVideoTrack triggers
onRenegotiationNeeded but the callback was empty — the remote peer
never received the updated SDP, so video never appeared on their side.
This wires up the full renegotiation flow using the existing
CallRenegotiateEvent (kind 25055):
- WebRtcCallSession: forward onRenegotiationNeeded to a callback
- CallController: create and send renegotiation offers, handle
incoming renegotiation offers by creating answers
- CallManager: route CallRenegotiateEvent, allow CallAnswerEvent
during Connected state for renegotiation answers
https://claude.ai/code/session_01WdmqktFBjXKB6PYRZ5b4FD
When a peer disables their camera, the remote side was showing a frozen
last frame because the VideoTrack reference remained non-null. This adds
a VideoSink-based frame monitor that detects when frames stop arriving
and transitions the UI back to the voice call avatar view.
https://claude.ai/code/session_01WdmqktFBjXKB6PYRZ5b4FD
Adds an ephemeral variant of GiftWrap for transient encrypted messages
that relays don't need to persist. EphemeralGiftWrapEvent extends
GiftWrapEvent so all existing processing paths (decryption, routing,
notifications, call signaling) automatically handle it via type
hierarchy. Relay subscription filters are updated to request both kinds.
https://claude.ai/code/session_0157X96G6HLTzYxkdX9pyTSJ
When the user disables video, the SurfaceViewRenderer kept showing
the last captured frame (frozen). Now the local video PiP is only
rendered when isVideoEnabled is true — when camera is off, the PiP
disappears entirely revealing the black background.
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
The d-tag is the article's identity in Nostr addressable events.
Changing it on edit would create a new article instead of updating
the existing one. The slug field is now disabled when isEditing is true.
https://claude.ai/code/session_011JuQbdA12WdPxC7aGvUBqJ
Four bugs fixed:
1. _isVideoEnabled defaulted to true — voice calls showed the
camera icon as "active" even though no video was being sent.
Changed default to false; only set true when video track is
actually created (video call initiation or acceptance).
2. cleanup() reset _isVideoEnabled to true — next call started
with wrong state. Changed to false.
3. stopCamera() disposed the capturer but toggleVideo re-enable
path only called setVideoEnabled(true) without restarting the
camera. No frames were captured. Now re-enable path calls
startCamera() to create a fresh capturer.
4. startCamera() made public on WebRtcCallSession with guard
against double-start (returns early if cameraCapturer != null).
State flow is now:
- Voice call: _isVideoEnabled=false, icon shows "camera off"
- Tap camera: creates track + starts camera, _isVideoEnabled=true
- Tap camera again: stops camera + disables track, =false
- Tap camera again: restarts camera + enables track, =true
- Video call: _isVideoEnabled=true from start, camera running
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
Redesigns the LongFormPostScreen to match the reference UI with:
- Visual banner image placeholder with dashed border (clickable to upload)
- Borderless large title field with placeholder styling
- Labeled Summary section
- URL Slug field mapped to the d-tag for user-defined article identifiers
- Tag/hashtag chip input with add button and removable chips
- Tags are included as hashtags in the published event
Adds tags and slug state to LongFormPostViewModel, wires them into
createTemplate() for event publishing, and loads them from drafts.
https://claude.ai/code/session_011JuQbdA12WdPxC7aGvUBqJ
When a call starts as voice-only, no video track exists. Tapping
the camera toggle was calling setVideoEnabled(true) on a null
track, doing nothing.
Now toggleVideo() checks if a video track exists. If not, it
creates one on-demand (addVideoTrack + startCamera), upgrading
the voice call to include video. If toggling off, it stops the
camera to save battery.
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
WebRTC's Camera2Session uses WindowManager to get device orientation
for frame rotation. WindowManager requires a visual (Activity)
context — using Application context throws IllegalAccessException.
Changed initCallController to pass the Activity context directly
instead of context.applicationContext.
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
Video calls were failing with SecurityException because only
RECORD_AUDIO was requested at runtime. CAMERA permission is also
required for Camera2Capturer to open the front-facing camera.
Changes:
- CallPermissions now uses RequestMultiplePermissions instead of
RequestPermission, with isVideo parameter to request CAMERA
alongside RECORD_AUDIO for video calls
- ChatroomScreen passes isVideo=true for the video call button
- CallScreen passes isVideo based on call type when accepting
incoming video calls
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
With Unified Plan SDP semantics (which we set in RTCConfiguration),
onAddStream is deprecated and doesn't fire. Remote media tracks
arrive via onAddTrack(RtpReceiver, MediaStream[]) instead.
Changed WebRtcCallSession:
- onRemoteStream callback renamed to onRemoteVideoTrack(VideoTrack)
- onAddTrack now extracts VideoTrack from RtpReceiver.track()
- onAddStream kept as fallback for Plan B compatibility
This was why video never appeared after connecting — the remote
video track was never captured and _remoteVideoTrack stayed null.
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
When initiateCall() runs async (Dispatchers.IO), navigation to
the ActiveCall screen happens before CallManager state changes
from Idle to Offering. The CallScreen sees Idle and immediately
calls onCallEnded() → popBack(), causing the screen to flash
and disappear.
Fix: CallScreen now waits 500ms on Idle before popping back.
If the state transitions to Offering within that window (normal
case), the screen stays. If it's still Idle after 500ms (no call
in progress), it pops back as before.

Major additions to the NIP specification:
- Gift wrap expiration: documented that outer gift wraps MUST
include expiration tags so relays can garbage-collect signaling
- Event structures: added full JSON examples with all required
fields (pubkey, id, sig, expiration, alt tags)
- ICE candidate buffering: documented that candidates MUST be
buffered while ringing and NOT cleared on accept
- Staleness and deduplication: documented 20s staleness check
and event ID dedup as spam prevention requirements
- NAT traversal: added TURN server guidance for same-WiFi and
restrictive network fallback (~20% of cases)
- Audio routing: documented MODE_IN_COMMUNICATION, earpiece/
speaker/Bluetooth SCO cycling, ringback tone, ringtone
- Platform integration: foreground service (microphone type),
proximity wake lock, PiP mode, runtime permissions
- Error handling: SDP creation failures, ICE_CONNECTION_FAILED,
session creation errors
- JSON escaping: noted that ICE candidate SDP strings MUST be
properly escaped in the content JSON
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
All GiftWrapEvent.create() calls in WebRtcCallFactory now pass
expirationDelta=20 so relays can garbage-collect the wraps after
the signaling data is no longer relevant. The actual expiration
timestamp is createdAt + 20s + 2 days (to account for the
randomized createdAt in NIP-59 gift wraps).
Previously only the inner events had expiration tags — the outer
gift wraps persisted indefinitely on relays.
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
- Add case-insensitive role matching in ParticipantTag (accepts both
"host" and "Host" from other clients per NIP-53 spec)
- Add PARTICIPANT role to ROLE enum per NIP-53 spec
- Add MeetingSpaceEvent (30312), MeetingRoomEvent (30313), and
MeetingRoomPresenceEvent (10312) consumption in LocalCache
- Create rendering composables for MeetingSpaceEvent and MeetingRoomEvent
with status flags (OPEN/PRIVATE/CLOSED for spaces, LIVE/PLANNED/ENDED
for rooms) and participant display
- Add meeting kinds to all discovery feed relay filters (global, authors,
hashtag, geohash, community)
- Add meeting kinds to ChannelCardCompose and LiveActivityCard thumb
rendering
- Add meeting kinds to KindRegistry search aliases
https://claude.ai/code/session_01CJ6xfY9gRA1c5r4T1SrUuv
#3 JSON escaping: CallIceCandidateEvent.serializeCandidate() now
escapes backslashes and quotes in SDP/sdpMid strings before
interpolation. Prevents malformed JSON when SDP contains special
characters.
#4 Thread safety: remoteDescriptionSet changed from Boolean to
AtomicBoolean to prevent race conditions between WebRTC callback
threads and main thread accessing the flag simultaneously.
#5 Async cleanup: hangup() no longer calls cleanup() synchronously
after launching the coroutine. Cleanup is now triggered by the
CallManager state collector when Ended state is reached, avoiding
resource disposal during active WebRTC callbacks.
#7 EglBase leak: createWebRtcSession() now wraps initialize() and
createPeerConnection() in try-catch that disposes the session on
failure, preventing EGL context leaks from failed initialization.
#10 SDP failure: createOffer/createAnswer onCreateFailure() now
calls onError() to surface SDP creation failures to the user
instead of silently logging them.
#11 Notification age: EventNotificationConsumer now uses
CallOfferEvent.EXPIRATION_SECONDS (20s) instead of hardcoded 30s
to align with the actual event expiration.
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
Audio route cycling: the speaker button now cycles through
Earpiece → Bluetooth → Speaker (or Earpiece → Speaker if no
Bluetooth device is connected).
CallAudioManager:
- Detects Bluetooth SCO/A2DP/BLE headset devices via AudioManager
- Manages Bluetooth SCO connection (startBluetoothSco/stopBluetoothSco)
- BroadcastReceiver monitors SCO state changes — auto-falls back
to earpiece if Bluetooth disconnects during call
- Exposes audioRoute and isBluetoothAvailable as StateFlows
CallController:
- Replaced toggleSpeaker() with cycleAudioRoute() which delegates
to CallAudioManager.cycleAudioRoute()
- Exposes audioRoute and isBluetoothAvailable flows to UI
CallScreen:
- Audio route button shows context-aware icon:
VolumeOff (earpiece), VolumeUp (speaker), BluetoothAudio
- Blue tint for Bluetooth, cyan for speaker, white for earpiece
Manifest: BLUETOOTH_CONNECT permission added.
Strings: call_bluetooth string resource added.
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
Add OpenRelay (metered.ca) free TURN servers to IceServerConfig
as defaults alongside STUN. This fixes calls between devices on
the same WiFi network where hairpin NAT isn't supported — the
~20% case where STUN-only fails.
TURN servers on ports 80, 443, and 443/TCP to bypass corporate
firewalls. Uses openrelayproject public credentials (20GB/month
free tier).
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
Localized strings:
- Added 28 string resources for all call UI text in strings.xml
- Replaced hardcoded strings in CallScreen, CallForegroundService,
NotificationUtils, and RenderRoomTopBar with stringRes() calls
- Technical error messages in CallController remain English (no
composable context available)
Picture-in-Picture:
- EnterPipOnLeave composable observes lifecycle and enters PiP
mode when app goes to background during active call
- MainActivity manifest updated with supportsPictureInPicture and
smallestScreenSize configChange
- 9:16 aspect ratio for portrait PiP window
ICE candidate fix (from logcat diagnosis):
- acceptIncomingCall() no longer clears pendingIceCandidates at
start — candidates buffered while ringing were being wiped
before flushPendingIceCandidates() could apply them
- This was causing "Flushing 0 buffered ICE candidates" on callee
StrictMode fix:
- initiateCall/acceptIncomingCall now run WebRTC session creation
on Dispatchers.IO to avoid DiskReadViolation from native lib
loading on main thread
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
Critical fixes:
- CallController.initiateCall/acceptIncomingCall now validate
WebRTC session creation with try/catch and null check before
proceeding. Errors shown to user via errorMessage flow.
- AccountViewModel.initCallController() is now @Synchronized to
prevent double initialization. EventProcessor callManager wired
before creating CallController. Callbacks set before exposing
controller to avoid timing races.
- Removed duplicate state (currentCallId/currentPeerPubKey) from
CallController — uses callManager.currentCallId()/
currentPeerPubKey() as single source of truth.
- Removed dead network callback code (was only logging).
Code quality:
- CallScreen null-safety patterns now use remember{} for fallback
StateFlow instances instead of creating new ones per recomposition.
- Removed dead rememberCallPermissionLauncher from CallPermissions.
- CallController cleaned up from 363 to 304 lines.
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
1. Move UI toggle state out of CallState.Connected:
- Removed isAudioMuted/isVideoEnabled/isSpeakerOn from domain
CallState. These are UI concerns, not call state.
- Added StateFlows for toggles in CallController (isAudioMuted,
isVideoEnabled, isSpeakerOn) with proper toggle methods.
- CallScreen reads toggle state from CallController flows.
- Removed toggleAudioMute/toggleVideo/toggleSpeaker from
CallManager (no longer manages UI state).
2. Move ICE candidate parsing to quartz layer:
- Added candidateSdp(), sdpMid(), sdpMLineIndex() parsers and
serializeCandidate() to CallIceCandidateEvent in quartz.
- Removed companion object with parseIceCandidate/
serializeIceCandidate from CallController.
- CallController now uses quartz-layer parsing directly.
- Updated IceCandidateSerializationTest accordingly.
3. Add helper methods to CallManager:
- currentCallId() and currentPeerPubKey() extract from any
active state, reducing repeated when expressions.
4. Fix empty callId bug in ChatroomScreen:
- Navigation to ActiveCall now uses callManager.currentCallId()
instead of hardcoded empty string.
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
Temporary diagnostic logging to identify why calls hang at
Connecting. Logs added to:
- CallManager.onSignalingEvent: event kind, age, state
- CallController: answer received, ICE candidates (buffered vs
direct), flush count, local ICE generation
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
1. Audio mode: AudioManager switches to MODE_IN_COMMUNICATION on
Connecting, restores to MODE_NORMAL on call end. Audio routes
through earpiece by default during calls.
2. Notification actions: Accept/Reject buttons added to incoming
call notification for quick action without opening the app.
3. Background handling: Full-screen intent brings app to foreground.
CallManager state persists in ViewModel so the call screen
picks up current state when navigated to via notification.
4. Call screen icons: Replaced text labels with Material icons -
Mic/MicOff for mute, Videocam/VideocamOff for camera,
VolumeUp/VolumeOff for speaker. Color-coded toggle states.
5. Video rendering: SurfaceViewRenderer composable wraps WebRTC
video tracks. Remote video displays full-screen, local video
as a small PIP in the top-right corner. Falls back to avatar
display when no video tracks are active.
6. Ringback tone: ToneGenerator plays TONE_SUP_RINGTONE during
Offering state (caller hears ringing). Stops on connect/end.
7. Error handling: CallController catches WebRTC session creation
failures, SDP errors, and ICE failures. Errors exposed via
errorMessage StateFlow and displayed as Snackbar on call screen.
8. Network handling: ConnectivityManager.NetworkCallback registered
during active calls to detect WiFi/cellular changes.
Unregistered on call end.
