Spring stomp web sockets client for android

Question

Can somebody please let me know how to connect to spring stomp web socket from android client.

WebSocketConfig.java

import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.simp.config.MessageBrokerRegistry;
import org.springframework.web.socket.config.annotation.AbstractWebSocketMessageBrokerConfigurer;
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker;
import org.springframework.web.socket.config.annotation.StompEndpointRegistry;

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker("/pushticket");
        config.setApplicationDestinationPrefixes("/rest");
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/ticket").withSockJS();
    }

}

PushMessageNotifier.java

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.messaging.simp.SimpMessagingTemplate;
import org.springframework.scheduling.annotation.Async;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.stereotype.Service;    

@Service
@EnableAsync
public class PushMessageNotifier {

    private SimpMessagingTemplate simpMessagingTemplate;

    @Autowired
    public PushMessageNotifier(SimpMessagingTemplate simpMessagingTemplate) {
        this.simpMessagingTemplate = simpMessagingTemplate;
    }

    @Async
    public Boolean pushToUI(TicketView ticketView) {
        Boolean result = false;
        if (null != ticketView) {
            this.simpMessagingTemplate.convertAndSend("/pushticket/ticket", ticketView);
            result = true;
        }
        return result;
    }

}

Please tell me how can I connect to this socket from android app? Even I don't have idea which android client I need to use to connect to this socket and topic. Thanks in advance

Its been ages since the question is asked but it shows up on google and have not received any accepted answer hence...

• this can be achieved easily using following library https://github.com/NaikSoftware/StompProtocolAndroid
• Important note: which documentation fails to communicate effectively: In case of SockJS lets assume we have to use URL like http://server-host:8080/stompEndpoint but in android it must be ws://server-host:8080/stompEndpoint/websocket. Where differences are 1) http vs ws 2) Appended /websocket in android variant of URL
