What is meaning of Android?

Andros-Man, Roid-like or similar- an artificial human-like creature as distinct from a robot which has metallic skin and is often only vaguely human-like like those in Star Wars or Lost In Space. Androids could (blend in) with humans and if used by ( who is to say they are not) by an intelligence agency-well they could have serious possibilities. androids, like UFOs are pretty much an ( Above Eyes Only) topic, at least officially, science fiction novels- some really good have been done on the theme. By the wqay the word is derived from two Greek words, andros and the roid suffix.
