Androids! I want to know EVERYTHING.

Can someone hit me up on the whole Android thing coming up in the next Chaos patch? I always saw stuff about it but not really in detail. I want to know what they are, what they do, how do you customize it, and yeah other stuff too. I just want a big layout of things about Androids. I am very interested. Also, are their parts tradeable to another character? I'm making my main a Jeweler but I want an Android on there.

Thanks!
