There are some libraries to implement WebSocket usage in an unobtrusive fashion. Apparently, there are many libraries out, but what I really looking is a modern and small library which I can use on Android or Java in generall to implement my WebSocket usage from the client side.
So far I have found:
I am missing a bit the differences of the differnet libraries. JAX-RS 2.0 for instance seems to be a great foundation for a lot of implementations, but I also went with Square's Retrofit for my RESTful Client because it was just leaner and easy to integrate.
I just work on one of my first web socket app in android. So I do lot of R&D before I starting and at last I found these two libs are very simple and useful for my requirement.
1 ) AndroidAsync (For clients )
2 ) Java-WebSocket (https://github.com/TooTallNate/Java-WebSocket ) for Server
Both are very simple and easy to use.
