Edit:

thanks to @anubhav-gupta, Through SDK Manager, I can only upgrade to version r18-beta1.

after the upgrade I face up with this error:

Android NDK: APP_STL gnustl_static is no longer supported. Please switch to either c++_static or c++_shared

Edit: update NDK to r15 and The problem was solved.

Answer 1

The main problem is in this line 'struct stat' has no member named 'st_atim' If you're using a modern version of the NDK, you'll have a modern struct stat: https://android.googlesource.com/platform/bionic/+/master/libc/include/sys/stat.h

Note that you need to be using the NDK's unified headers to get the up to date headers. This is the default in r15, but opt-in for r14.
