Websocket library on Android

Novice here. Trying to setup websocket communications between an Android app and node.js on the server side.

The problem I have is the lack of consensus on the Internets on which packages to use.

On node.js

- socket.io, often said to be stuck in the v0.9 version

- engine.io

- Autobahn

.. and more

On Android there are

- https://github.com/koush/android-websockets

- https://github.com/Gottox/socket.io-java-client

- Autobahn

Does HN have a favorite? What's HN's experience on mobile app use of websocket?
