Event Listeners

Event listeners enable you to receive events from ChatCamp backend in real time. You may use an event listener to execute a specific workflow for any server side event. Each event listener contains various callback methods. You may override these callback methods to react to a particular chat event.

Channel Listeners

Channel listeners are designed to handle events of a channel, group or open both.

ChatCamp.addChannelListener(CHANNEL_LISTENER_ID, new ChatCamp.ChannelListener() {
	
  @Override
  public void onOpenChannelMessageReceived(OpenChannel openChannel, Message message){
  }

  @Override      
  public void onGroupChannelMessageReceived(GroupChannel groupChannel, Message message){
  }
  
  @Override
  public void onGroupChannelUpdated(GroupChannel groupChannel){
  }
  
  @Override
  public void onGroupChannelTypingStatusChanged(GroupChannel groupChannel){
  }
  
  @Override
  public void onGroupChannelReadStatusUpdated(GroupChannel groupChannel){
  }

  @Override
  public void onTotalGroupChannelCount(int count, TotalCountFilterParams totalCountFilterParams){
  }
  
  @Override
  public void onGroupChannelParticipantJoined(GroupChannel groupChannel, Participant participant){
  }
  
  @Override
  public void onGroupChannelParticipantLeft(GroupChannel groupChannel, Participant participant){
  }
  
  @Override
  public void onGroupChannelMessageUpdated(GroupChannel groupChannel, Message message) {
  }
  
  @Override
  public void onOpenChannelMessageUpdated(OpenChannel groupChannel, Message message) {
  }
  
  
});

CHANNEL_LISTENER_ID is a unique channel listener id and it is a string.

You may remove a channel listener by using its id as shown below.
