Combat:
Androids are friendly to all humans they meet until they are attacked.  At that time, they will try to leave the human be, but will attack if the human persists.  All other species encountered are taken as neutral, unless the android has met that species before and then reacts based on that previous encounter.

Sentient Construct: Androids quite simply are constructs given life and the ability to reproduce.  Since they are not quite the same thing as a normal living being, therefore the android has an Spell Resistance of 5 against all magic.  They are living, breathing creatures, but they are still different enough that such spells.  They can become spell casters themselves, but they are treated as though they have a constant 5% chance of Arcane Spell Failure due to their pseudo-mechanical nature.

Great Cyber Tolerance: All androids are born part machine.  This allows them to be easily installed with new cybernetic parts (see my conversion of cybergear), giving them two free neural data slots and a Good quality nanocomputer for free.  Also, they figure their cybertolerance score as Constitution +4 and have no chance of a cybernetic implant being rejected by their bodies.  They also get the Cybertech feat for free.

Skills: +4 bonus to Disable Device and Knowledge (Technology) checks.

Society:
See the Alternity Gamma World campaign setting for more information.

Characters:
Androids are most commonly monks.  This may seem strange, but androids have a will and determination that few other species can comprehend.  Many androids are also fighters, but magic-using classes are extremely rare among their kind.
