Centrifugo android client

Usage

Create client and connect:

String centrifugoAddress = "wss://centrifugo.herokuapp.com/connection/websocket";
String userId = "...";
String userToken = "..."; //nullable
String token = "...";
String tokenTimestamp = "...";
Centrifugo centrifugo = new Centrifugo.Builder(centrifugoAddress)
                        .setUser(new User(userId, userToken))
                        .setToken(new Token(token, tokenTimestamp))
                        .build();
centrifugo.connect();

Subscribe to channel:

String channel = "my-channel";
centrifugo.subscribe(new SubscriptionRequest(channel));

Listen to events:

Connection events

centrifugo.setConnectionListener(new ConnectionListener() {

        @Override
        public void onWebSocketOpen() {
        }

        @Override
        public void onConnected() {
        }

        @Override
        public void onDisconnected(final int code, final String reason, final boolean remote) {
        }

});

Subscription events

centrifugo.setSubscriptionListener(new SubscriptionListener() {

        @Override
        public void onSubscribed(final String channelName) {
        }

        @Override
        public void onUnsubscribed(final String channelName) {
        }

        @Override
        public void onSubscriptionError(final String channelName, final String error) {
        }

});

Messages, published into channel

centrifugo.setDataMessageListener(new DataMessageListener() {

        @Override
        public void onNewDataMessage(final DataMessage message) {
        }

});

Join and leave events

centrifugo.setJoinLeaveListener(new JoinLeaveListener() {

        @Override
        public void onJoin(final JoinMessage joinMessage) {
            message(joinMessage.getUser(), " just joined " + joinMessage.getChannel());
        }

        @Override
        public void onLeave(final LeftMessage leftMessage) {
            message(leftMessage.getUser(), " just left " + leftMessage.getChannel());
        }

});
