Example

Here is the usage of all the events mentioned in this page.

Kotlin

private val meetingEventListener: MeetingEventListener = object : MeetingEventListener() {
  override fun onParticipantJoined(participant: Participant) {
    Log.d("VideoSDK", participant.displayName + " joined");
  }

  override fun onParticipantLeft(participant: Participant) {
    Log.d("VideoSDK", participant.displayName + " left");
  }

  override fun onWebcamRequested(participantId: String, listener: WebcamRequestListener) {

    // participantId, will be the id of participant who requested to enable mic

    // if accept request
    listener.accept()

    // if reject request
    listener.reject()
  }

  override fun onMicRequested(participantId: String, listener: MicRequestListener) {

    // participantId, will be the id of participant who requested to enable mic

    // if accept request
    listener.accept()

    // if reject request
    listener.reject()
  }
}

override fun onCreate(savedInstanceState: Bundle?) {
  //...

  // add listener to meeting
  meeting!!.addEventListener(meetingEventListener)
}

Java

private final MeetingEventListener meetingEventListener = new MeetingEventListener() {
  @Override
  public void onParticipantJoined(Participant participant) {
      Log.d("VideoSDK", participant.getDisplayName() + " joined");
  }

  @Override
  public void onParticipantLeft(Participant participant) {
      Log.d("VideoSDK", participant.getDisplayName() + " left");
  }

  @Override
  public void onWebcamRequested(String participantId, WebcamRequestListener listener) {

    // participantId, will be the id of participant who requested to enable webcam

    // if accept request
    listener.accept();

    // if reject request
    listener.reject();
  }

  @Override
  public void onMicRequested(String participantId, MicRequestListener listener) {

    // participantId, will be the id of participant who requested to enable mic

    // if accept request
    listener.accept();

    // if reject request
    listener.reject();
