Could an alien gestate inside an android?

I don't think that's possible, facehuggers detect a host based on their "biological" make up. Even though the comics touch on facehugger embryos gestating in hosts with bad health, the chestbursters never form because of the lack of biological material to feed off. Think of the embryos as human, in pregnancy the foetus feeds off the host body's food ingestion and receives nutrition via the placenta. As Artificial Person's like David has no need to ingest food, he only did so on the Prometheus mission to emulate human traits to make his counterparts more comfortable. And I don't believe David's biofluid would be sufficient to support an alien embryo.
