Re: The Apple logo is an apple...
The Oxford English Dictionary has Android as meaning 'having the likeness of a man'.
The rough convention in technology and science fiction is: Androids are robots, but not all robots are androids. I say 'rough' because of course the fun of the genre is that writers can make their own rules and play with boundaries
Androids are robots designed to look human or near enough, so: Simulants from Blade Runner, some Cylons from the new BSG, Ash and Bishop from Alien, Data from StarTrek, and R. Daneel Olivaw as examples.
The middle ground would be C3PO from StarWars - not designed to pass for human, but to operate well in human environments. Of course 'man-like' is open to interpretation.
