Chat events
Events Litener.
Interaction with library is possible essentially through two listeners: MqttChatListener and  MqttChatFCMListener. 
MqttChatListener events : are called when application is in foreground or is still in task list.
MqttChatFCMListener events : are called by google play firebase services when application is closed and FCM feature is activated. Click here to see how to activate FCM in Mqttchat android library.
MQTTChat listener
You can capture all MQTT chat events using a MqttChatListener :
1
MqttChatListener listener= new MqttChatListener() {
2
​
3
            @Override
4
            public void onLoadComplete() {
5
              Log.i(Tag,"MQTT Chat load complete");
6
            }
7
​
8
            @Override
9
            public void onUserPresenceUpdate(int i, String s, boolean b, boolean b1, String s1) {
10
             Log.i(Tag,"User presence update : userId:"+i +"; new status:"+s+" ;voice capacity:"+b +" ;video capacity:"+b1+"; timestamp:"+s1);
11
            }
12
​
13
            @Override
14
            public void onSendMessage(int i, Message message) {
15
                Log.i(Tag,"Logged user send message to userId :"+i +"; message:"+message.toString());
16
            }
17
​
18
            @Override
19
            public void onAckMessage(int i, Ack ack, Message message) {
20
                Log.i(Tag,"Logged user received Ack from server for message sent to userId :"+i +"; ack :"+ack.toString()+"; message:"+message.toString());
21
            }
22
​
23
            @Override
24
            public void onRejectMessage(int i, String s, Message message) {
25
                Log.i(Tag,"Logged user has sent message to userId:"+i+"; message was rejected by server because of :"+s+"; and message content :"+message.toString());

            }

            void onReceiveNotification(Notification notification){

            @Override

Copied!
To add  listener to MQTT chat:
1
 Mqttchat.getmInstance().addMqttchatListener(listener);
Copied!
And to remove listener :
1
  Mqttchat.getmInstance().removeMqttchatListener(listener);   
Copied!
You can add many listeners in differents activities or fragments. So you can catch events where you need.

void onAckMessage(int toUserId, Ack ack,Message message);

MQTTChat FCM listener
Two types of FCM events are provided by the listener: events following an MQTT Chat notification received. Or else an FCM  notification message not sent by MQTT Chat but received by FCM service. It can be sent by your server or another library.
1
Mqttchat.getmInstance().addMqttchatFCMListener(new MqttChatFCMListener() {
2
    @Override
3
    public void onReceiveFCMNotification(boolean notificationsSettingEnabled, int toUserId, Notification notification) {
4
        
5
    }
6
​
7
    @Override
8
    public void onReceiveOtherFCMData(com.google.firebase.messaging.RemoteMessage message) {

Event
Description
void onReceiveFCMNotification(boolean notificationsSettingEnabled, int toUserId, Notification notification);
