Hi,

your question is a little bit unclear. Do you want to write a pure chat application or more something like a messenger. For a messenger I think using the Google Cloud Messaging for Android(GCM) makes most sense. With GCM it is not required to poll for new messages or hold a TCP connection open all the time. You find more information here: http://developer.android.com/google/gcm/index.html . I don't know if GCM would be also the first choice for a chat application. 

For writing a chat application there are nice small examples including source code like that one here: https://code.google.com/p/simple-android-instant-messaging-application/ . There are also very easy to use XMPP libraries available that handles all the networking stuff for you. One example is Smack API: http://www.igniterealtime.org/projects/smack/index.jsp

Hope this helps,
Alex

Hi Alexander Weggerle,

Thank you for suggestion, I'm trying to make a web socket with html and jsp, is for work in real time, when you do some on an app, if I have the same app and permissions, I will see this change on app in time real.

Hi,

so you mean you want to use HTML5 web sockets on the client side (Android) and Java Server Pages(JSP) on the server side? 

Thanks,
Alex

Hi, 

Not initially think it will be both client and web server, android not yet.

Thanks you!

[Ashwin_S_Ashok]

Hi Ashwin, I have tried make an app that refresh on time real in each user of same app, the changes doing for the other user, like a chat.

Hi,

just some more suggestions which might help you to write your application.I think I found a very sample using JSP for a chat application: http://ben-bai.blogspot.de/2012/01/jsp-practice-simple-chat.html . 

I think you should also consider to use node.js instead of JSP. It is easier to use especially for html5 projects. There is a nice tutorial here: http://net.tutsplus.com/tutorials/javascript-ajax/real-time-chat-with-nodejs-socket-io-and-expressjs/

If you want to extend your chat for audio and video you can use WebRTC for your application. There is a really nice GoogleIO Talk about it and here is a getting started guide. 

I hope this helps you!

Hi Alexander,I need to apply to node js mvc.

[Alexander_W_Intel]

Hi,

I never used a MWC framework with node.js. But this one looks very promising: http://sailsjs.org . It has a nice documentation. Does this help you?

Thanks,
Alex
