/usr/include missing from NDK (r16b)

Question

I've just installed NDK (r16b) using the SDK manager, but is ~/Library/Android/sdk/ndk-bundle/platforms/android-24/arch-x86/usr/include (I'm on OS X) supposed to exist? I can't seem to find it. I have ~/Library/Android/sdk/ndk-bundle/platforms/android-24/arch-x86/usr/lib. The following is the result from running tree at /arch-x86:

2 directories, 26 files

Is there a way to generate the include directory? I'm actually looking for the file ~/Library/Android/sdk/ndk-bundle/platforms/android-24/arch-x86/usr/include/android/api-level.h

Answer 1

In the latest SDK, api-level.h is located at

~/Library/Android/sdk/ndk-bundle/sysroot/usr/include/android/api-level.h

In the future, if you can not find one file due to the directory hierarchy changed, you can do like following to find out

$ cd ~/Library/Android/sdk/ndk-bundle
$ find . -name "api-level.h"
