Recommendation for Library/API for Chat App

Hi,

Has anyone developed a Web Sockets based Chat app?
I'm wondering what Libraries / APIs to use.

Some of my requirements are:
- Async send/recv of messages
- Send-Recv files (images, pdf etc)
- Maintain chat sessions when switching between Mobile data - Wifi - No Connectivity
- Prevent message loss during low or no connectivity
- Concurrent messaging from multiple devices

Please share your choices & reasons. I'd also like to know how your experience was?

Suggestions & advices welcome!

Thanks in advance
Sans

Re: Recommendation for Library/API for Chat App

I have never seen such a library that fits all your needs, though I managed to create a simple chat using socket.io-client-java library in a Service running in a background.
