Android NDK: Your APP_BUILD_SCRIPT points to an unknown file: Android.mk process_begin: CreateProcess(NULL, “”, …) failed

问题

I use NDK at first time and I have a problem, which I can't resolve about two days. I think the issue not unique, and the problem in some small details.

When I try to build example project I keep getting this error message when I try to compile using "ndk-build"

Android.mk
