- Include pending peers in hangup notification so ringing users get
immediate feedback instead of waiting for the 60s timeout
- Sign individual hangup events per peer with correct p-tag instead
of reusing a single event with the first peer's tag
- Stop treating ICE DISCONNECTED as terminal; only hang up on FAILED
since DISCONNECTED is often transient (network switch, packet loss)
- Send "busy" reject when receiving a call while already in one

RingtoneManager.getRingtone() and audio mode switching do disk I/O,
causing StrictMode DiskWriteViolation when called from the state
collector on the main thread. Wrap startRinging() and
switchToCallAudioMode() in withContext(Dispatchers.IO).
https://claude.ai/code/session_01LR8NmFGdMoDTVcfKjL7HWR
Add ability to invite new users into an ongoing call:
- CallManager.invitePeer() sends a call offer to a new peer using
the current callId, adding them to pendingPeerPubKeys
- CallController.invitePeer() exposes this to the UI layer
- Add PersonAdd button to connected call controls
- Add AddParticipantDialog with user search (reuses UserSuggestionState)
- New strings: call_add_participant, call_search_users
Rewrite CallScreenPreviews to showcase all call states:
1. Offering P2P call (Calling...)
2. Offering group call (3 avatars)
3. Connecting
4. Incoming voice call
5. Incoming video call
6. Incoming group call (4 avatars)
7. Connected P2P voice call with controls
8. Connected muted + video + speaker
9. Connected group call with pending peers
10. Connected with Bluetooth audio
11. Call ended
12. Large group (5+ members, +N badge)
13. PiP calling
14. PiP connected
https://claude.ai/code/session_01LR8NmFGdMoDTVcfKjL7HWR
The call now starts immediately when the first peer answers instead
of waiting for all participants. Remaining peers are tracked as
pending and shown in the UI with a "Waiting for others to join..."
indicator. When a pending peer answers, they move to the connected
set. If a pending peer rejects or hangs up, they're silently removed.
Changes:
- Add pendingPeerPubKeys to Connecting and Connected states
- Add allPeerPubKeys helper on Connected for UI rendering
- Split peers into connected/pending on first answer in onCallAnswered
- Handle subsequent answers in Connecting and Connected states
- Carry pending peers through Connecting -> Connected transition
- Show all peers (connected + pending) in call UI avatars
- Display "Waiting for others to join..." when pending peers exist
https://claude.ai/code/session_01LR8NmFGdMoDTVcfKjL7HWR
When a peer hangs up or rejects in a group call, remove them from the
participant set instead of ending the entire call. The call only ends
when no peers remain (all others left). Similarly, if a peer rejects
during the Offering phase of a group call, remove them but continue
ringing remaining peers.
For incoming group calls, if the original caller hangs up the call
ends immediately. If another group member leaves, the call continues
as long as at least 2 members (including self) remain.
https://claude.ai/code/session_01LR8NmFGdMoDTVcfKjL7HWR
- Add GroupCallPictures composable showing up to 4 user avatars in
a grid layout (same pattern as NonClickableUserPictures in chat)
- When >4 members, show 3 avatars + a "+N" badge in the 4th slot
- Add GroupCallNames composable showing up to 2 names + "+N" remaining
- Update CallInProgressUI, IncomingCallUI, ConnectedCallUI, PipCallUI,
and PipConnectedCallUI to pass full peerPubKeys/groupMembers sets
instead of only .first()
https://claude.ai/code/session_01LR8NmFGdMoDTVcfKjL7HWR
- Add MODIFY_AUDIO_SETTINGS for audio routing (speaker, earpiece, BT SCO)
- Add BLUETOOTH permission for API 26-30 (maxSdkVersion=30)
- Request BLUETOOTH_CONNECT at runtime on API 31+ for BT audio
- Add FOREGROUND_SERVICE_CAMERA for video calls on API 34+
- Update foreground service type to microphone|camera for video calls
- Guard Bluetooth operations with permission check in CallAudioManager
- Add uses-feature for microphone with required=false
https://claude.ai/code/session_01LR8NmFGdMoDTVcfKjL7HWR
On SDK 36 starting a foreground service with type microphone requires
RECORD_AUDIO to be granted at the moment startForeground() is called.
When the permission isn't available (e.g. revoked between call start
and peer connection) the service now falls back to a generic foreground
type instead of crashing with a SecurityException.
https://claude.ai/code/session_01WafqMofFQfWCQA5TcLvHRb
Adds voice and video call buttons to the group DM top bar, matching
the existing 1-on-1 DM header. When tapped in a group chat, the
buttons invoke initiateGroupCall() which sends gift-wrapped offers
to every group member under a single call-id.
https://claude.ai/code/session_01WafqMofFQfWCQA5TcLvHRb
Extends the NIP-AC P2P call signaling to support group calls by
sending individual gift-wrapped offers to each member of the group,
all sharing the same call-id.
- CallOfferEvent: add multi-pubkey build overload, groupMembers(),
isGroupCall(), and recipientPubKeys() helpers
- WebRtcCallFactory: add GroupResult type, createGroupCallOffer(),
createGroupHangup(), and createGroupReject() methods
- CallState: change peerPubKey to peerPubKeys (Set<HexKey>) across
Offering, Connecting, Connected, and Ended states; add groupMembers
field to IncomingCall
- CallManager: add initiateGroupCall() that creates a single signed
offer with p tags for every callee and gift-wraps it individually;
hangup sends to all peers in a group call
- CallController: add initiateGroupCall() entry point
- Tests: add group call offer tests for p tags, call-id, call-type,
and expiration
https://claude.ai/code/session_01WafqMofFQfWCQA5TcLvHRb
The code implements two protocol features not previously documented in
the NIP: (1) renegotiation responses use CallAnswer (kind 25051) to
complete the SDP handshake, and (2) self-addressed answer/reject events
notify other devices of the same user to stop ringing.
https://claude.ai/code/session_01XSjhzuVn8N4Q2hZAYMRGqM
Android 12+ blocks starting activities from BroadcastReceivers used
as notification trampolines. The Accept action now uses
PendingIntent.getActivity to launch CallActivity directly with
EXTRA_ACCEPT_CALL. CallActivity.onCreate/onNewIntent checks this
extra and accepts the incoming call.
The Reject action remains as a BroadcastReceiver since it doesn't
need to start an activity.
https://claude.ai/code/session_01Ak5tTkujpjNG1r5ASuPipZ
1. onStop() no longer hangs up call when user switches apps
- Added wasInPipMode flag to track if the activity was ever in PiP
- onStop only hangs up + finishes when PiP was dismissed (swiped away),
not when the user simply presses Home from the full-screen call UI
- Pressing Home from full-screen enters PiP via onUserLeaveHint
2. Removed triple-hangup from overlapping lifecycle methods
- onPictureInPictureModeChanged now only updates UI state
- onStop handles PiP dismissal only
- onDestroy only cleans up the PiP receiver (hangup already handled
by CallController's state collector on Ended)
3. CallNotificationReceiver guards against stale notifications
- Returns early if callManager/callController are null
- Only launches CallActivity if the call is still IncomingCall
- Cancels notification before any other action to prevent re-taps
https://claude.ai/code/session_01Ak5tTkujpjNG1r5ASuPipZ
Enable proper full-screen call experience when the phone is locked
or the app is in the background:
- CallActivity shows over lock screen (setShowWhenLocked/turnScreenOn)
- Manifest adds showOnLockScreen and turnScreenOn attributes
- Remove setSilent(true) from notification — it was blocking the
full-screen intent from triggering (channel silence is enough)
- Populate ActiveCallHolder eagerly in initCallController() so the
full-screen intent can launch CallActivity even when the Compose
UI is paused in the background
https://claude.ai/code/session_01Ak5tTkujpjNG1r5ASuPipZ
Both CallController and EventNotificationConsumer now load the
caller's profile picture via Coil before showing the notification,
so the large icon displays the caller's avatar instead of being
empty. The caller name was already loaded from LocalCache but now
the bitmap accompanies it.
https://claude.ai/code/session_01Ak5tTkujpjNG1r5ASuPipZ
- Track remote video aspect ratio in CallController via VideoFrame
rotatedWidth/rotatedHeight
- PiP uses video's aspect ratio when remote video is active, falls
back to 9:16 portrait for audio-only calls
- Observe isRemoteVideoActive to update PiP params when video
starts/stops during a call
https://claude.ai/code/session_01Ak5tTkujpjNG1r5ASuPipZ
- Restore Rational(9, 16) portrait aspect ratio for PiP window
- Add onStop handler: when PiP is dismissed via X button, hang up
the call and finish the activity (mirrors PipVideoActivity pattern)
- onPictureInPictureModeChanged also hangs up if activity is finishing
https://claude.ai/code/session_01Ak5tTkujpjNG1r5ASuPipZ
1. Notification: silence channel sound (CallAudioManager handles ringtone),
use CallNotificationReceiver for accept/reject actions instead of
launching MainActivity
2. Cancel call notification when call is accepted (Connecting state)
3. PiP: hang up call when PiP is dismissed (activity destroyed)
4. PiP: add RemoteAction buttons (hangup, mute toggle) since Compose
buttons are not interactive in PiP mode
5. PiP: show compact UI with smaller avatar (48dp) and smaller text
when in picture-in-picture mode
https://claude.ai/code/session_01Ak5tTkujpjNG1r5ASuPipZ
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).
https://claude.ai/code/session_01C8gevBfB8vLDFoBW3hnPeU
Separate the call UI into a dedicated CallActivity so it can enter
Picture-in-Picture mode independently of the main activity, allowing
users to continue browsing the app during an active call.
- Add CallActivity with PiP support via onUserLeaveHint
- Add ActiveCallHolder singleton to share call state between activities
- Launch CallActivity from call buttons and incoming call observer
- Remove in-app nav route for ActiveCall (now a separate activity)
- Remove EnterPipOnLeave composable (activity handles PiP directly)
https://claude.ai/code/session_01Ak5tTkujpjNG1r5ASuPipZ
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.
https://claude.ai/code/session_014espsysob7MrE8X8e75jFX
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.
https://claude.ai/code/session_014espsysob7MrE8X8e75jFX
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.
https://claude.ai/code/session_014espsysob7MrE8X8e75jFX
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.
https://claude.ai/code/session_014espsysob7MrE8X8e75jFX
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.
https://claude.ai/code/session_01JEzjceY3ZaCHz5kL4DsKic
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
