My concern was more how to support this platform. For the answer to the
next question I suspect that Boost can support Android only if the user
uses NDK.

Boost.Chrono has this on the buil

         <target-os>linux:<linkflags>"-lrt -lpthread"

Is there a specific target for Android I can use?

Would your scripts take care of -lrt?
What about -lpthread?

Have you requested the needed features already?
