bionic/libc/include/bits/fortify

今天编译assmip库的时候又出了这个问题，关键这个tm我之前是编译通过的

bionic/libc/include/bits/fortify/stdio.h:70: error: undefined reference to '__vsnprintf_chk'
bionic/libc/include/bits/fortify/stdio.h:43: error: undefined reference to '__vsnprintf_chk'

谷歌查了一下,找到了这个文件的源码https://android.googlesource.com/platform/bionic/+/master/libc/include/bits/fortify/stdio.h

在43行找到了如下的源码，看上面的注释 ANDROID_API >= ANDROID_API_J_MR1

也就是说android版本必须大于J,回去把minSdkVersion从15修改到19，果然编译通过了
