Core Rulebook, page 272 says there are spell effects targeting "living creatures" only:
Some effects restrict which targets can be selected. If an effect targets living creatures, it affects all creatures other than constructs and undead — in other words, biological or technobiological creatures that are alive.
So RAW "all creatures other than constructs and undead" means that if the creature is a construct, it is not considered a "living creature".
Androids are "both constructs and humanoids", therefore, they are constructs, therefore, they are not "living creatures":
For effects targeting creatures by type, androids count as both humanoids and constructs (whichever effect is worse).
Or are they? The rules are ambiguous:
- Androids are living creatures, because they are humanoids, and humanoids are "creatures other than constructs and undead"
- Androids are not living creatures, because they are constructs, so they are not "creatures other than constructs and undead"
The second ruling doesn't seem plausible. There are many beneficial effects that target living creatures only. For example, the Mystic Cure spell has "Targets one living creature" in its stat block. If androids are not "living creatures", how are they supposed to restore their Hit Points? Other means, for example, the Regeneration Table, means mention "living creatures" as well:
A living creature using a regeneration table is affected as if a 6th-level mystic cure spell as well as the remove affliction and restoration spells were cast on it
