I'm thinking about implementing something similar to 'my own on-site web chat widget'. Or more generic, some Q&A solution.
And while I can build the back-end myself (and prefer to), I'd like to use some kind of front-end app that's 3rd party software - preferably open-source. I'm not talking about the widget - but about the "operator app".
I'm looking for an android app that's configurable and has the option to trigger Android notifications near real-time.
Currently my best bet would be an IRC app. Someone posts to my web chat (or Q&A forum) and my back-end relays this post to my own IRC channel. Then: the Android app in question follows that channel and alerts me once people join the chat or post something (and I can immediately react). But I'm not that familiar with IRC.
I don't know if there's an even more lightweight solution. What I'd basically need is a configurable app, that can track (poll or more efficiently) some web resource, trigger an alert, and allow me to react in-app with responses to this update/event/inquiry/post.
