[guobosheng]

same issue

[reamal]

same issue
Android studio 3.0 canary 8

i saw this code in pthread.h

#if ANDROID_API >= 21
int pthread_condattr_setclock(pthread_condattr_t* _Nonnull, clockid_t) __INTRODUCED_IN(21);
#endif /* ANDROID_API >= 21 */

so modify the minsdk to 21 in gradle

defaultConfig {
...
minSdkVersion 21
targetSdkVersion 23
..
}

then build success
