How can I find the minimum supported platform for a given Android NDK? -

-

i sorry ask may elementary question. i'm working code library written in c. i've been building , running using ndk version 8e. using sdk 22, , minimum execution platform 8 (froyo, believe).

now i've introduced use of timerfd_create. looks earliest ndk includes sys/timerfd.h v20. (or doesn't) imply minimum execution platform?

thank you.

if use ndk platform android-21, library guaranteed load on devices run lollipop , higher. though android-3/arch-arm/usr/include/asm/unistd.h defines __nr_timerfd_create, functionality unavailable on lower platforms.
