Local
A data track published by the local participant. Obtain one from io.livekit.android.room.participant.LocalParticipant.publishDataTrack, then push frames with tryPush or send.
The publication stays live until unpublish is called, the SFU unpublishes the track, or the room disconnects. Dropping the last reference eventually unpublishes the track, but only once it is garbage collected — call unpublish to end the publication at a predictable point, or io.livekit.android.room.participant.LocalParticipant.withDataTrack to scope one to a block.
val result = room.localParticipant.publishDataTrack("telemetry")
result.onSuccess { track ->
track.tryPush(DataTrackFrame(payload))
track.unpublish()
}Types
Policy for send when the send queue is full.
