I have multiple questions :
Google announced that Hangout is replacing Gtalk from May 2013. So on their android devices some people have updated from Gtalk to Hangout while some are still using Gtalk. So if I have to use an API to transfer exchange data from my android app to Google Chat Messenger , how and what should I use to make it compatible for both.
What library should I use to integrate Gtalk/Hangout with my android app ? And where would I get something like SDK Reference Docs for Gtalk/Hangout ?
Can I get any sample implementation of the same anywhere(possibly GitHub) ?
