Installation issue in Android Studio

[epicshardz]

I follow the direction provided. However, whether I add the code you mention to my current project or try to build a project from these files to test it out. I run into the following errors:
`FAILURE: Build failed with an exception.

• What went wrong:
  A problem occurred configuring project ':vad'.

NDK not configured. Download it with SDK manager. Preferred NDK version is '21.0.6113669'.
`

Thanks in advanced for the help. I am very interested in seeing this run since its an offline VAD.

Well think I resolved it by installing the NDK version.
