Constructs a RtcChannelEventHandler

Properties

activeSpeaker ↔ UidCallback?

Reports which user is the loudest speaker.

getter/setter pair

audioPublishStateChanged ↔ StreamPublishStateCallback?

Occurs when the audio publishing state changes.

getter/setter pair

audioSubscribeStateChanged ↔ StreamSubscribeStateCallback?

Occurs when the audio subscribing state changes.

getter/setter pair

channelMediaRelayEvent ↔ MediaRelayEventCallback?

Reports events during the media stream relay.

getter/setter pair

channelMediaRelayStateChanged ↔ MediaRelayStateCallback?

Occurs when the state of the media stream relay changes.

getter/setter pair

clientRoleChanged ↔ ClientRoleCallback?

Occurs when the user role switches in a ChannelProfile.LiveBroadcasting channel. For example, from broadcaster to audience or vice versa.

getter/setter pair

connectionLost ↔ EmptyCallback?

Occurs when the SDK cannot reconnect to Meta's edge server 10 seconds after its connection to the server is interrupted.

getter/setter pair

connectionStateChanged ↔ ConnectionStateCallback?

Occurs when the network connection state changes.

getter/setter pair

error ↔ ErrorCallback?

Reports the error code of the RtcChannel instance.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

joinChannelSuccess ↔ UidWithElapsedCallback?

Occurs when the local user joins a specified channel.

getter/setter pair

leaveChannel ↔ RtcStatsCallback?

Occurs when a user leaves the channel.

getter/setter pair

localPublishFallbackToAudioOnly ↔ FallbackCallback?

Occurs when the published media stream falls back to an audio-only stream due to poor network conditions or switches back to video stream after the network conditions improve.

getter/setter pair

metadataReceived ↔ MetadataCallback?

Occurs when the local user receives the metadata, including the following parameters:

getter/setter pair

networkQuality ↔ NetworkQualityWithUidCallback?

Reports the last mile network quality of each user in the channel once every two seconds.

getter/setter pair

rejoinChannelSuccess ↔ UidWithElapsedCallback?

Occurs when a user rejoins the channel after being disconnected due to network problems.

getter/setter pair

remoteAudioStateChanged ↔ RemoteAudioStateCallback?

Occurs when the remote audio state changes.

getter/setter pair

remoteAudioStats ↔ RemoteAudioStatsCallback?

Reports the statistics of the audio stream from each remote user/broadcaster.

getter/setter pair

remoteSubscribeFallbackToAudioOnly ↔ FallbackWithUidCallback?

Occurs when the remote media stream falls back to audio-only stream due to poor network conditions or switches back to video stream after the network conditions improve.

getter/setter pair

remoteVideoStateChanged ↔ RemoteVideoStateCallback?

Occurs when the remote video state changes.

getter/setter pair

remoteVideoStats ↔ RemoteVideoStatsCallback?

Reports the statistics of the video stream from each remote user/broadcaster. The SDK triggers this callback once every two seconds for each remote user/broadcaster. If a channel includes multiple remote users, the SDK triggers this callback as many times.

getter/setter pair

requestToken ↔ EmptyCallback?

Occurs when the token has expired.

getter/setter pair
