The include directory contains the C-language header file for writing native extensions. The libs directory contains code libraries for use in AIR applications. By default, copying a directory on the Mac to a directory of the same name removes the existing files in the target directory it does not merge the contents of the two directories. Note: On Mac computers, make sure that you copy or replace the individual files in the SDK folders - not entire directories.
Note: Java is not required for end users to run AIR applications.
