To check if a participant is disconnected in LiveKit, you can use event handling specific to the SDK you are using: • Android SDK: Listen for the

ParticipantDisconnected

event. For example:

// This event is fired when a RemoteParticipant leaves after the local participant has joined
class ParticipantDisconnected(val room: Room, val participant: RemoteParticipant) : RoomEvent

• Swift SDK: Implement the

RoomDelegate

method:

func room(_ room: Room, participantDidDisconnect participant: RemoteParticipant)

• Unity SDK: Use the `ParticipantDisconnectedDelegate`:

public delegate void ParticipantDisconnectedDelegate(RemoteParticipant participant);

These events or delegates will automatically trigger when a participant disconnects, allowing your application to handle the situation accordingly.
