The file
ch02_project_ProjectActivity.h
is shown in Listing 2-2.

Your last step will be to create the C file
ch02.ccp
and compile it.
Native Library
Here is where all the work takes place. The implementation is provided in
ch02.ccp
(see Listing 2-3). This file lives in the
jni
folder within the project.
Note
Native libraries in Linux (also known as shared objects) are the equivalents of dynamic link
libraries (DLLs) in Windows. By convention, shared objects are named as
lib<NAME><VERSION>.so
.
