how can i import cpp files to my project

i have run cocos2d-x demo in simulator successed,but in my project i can not find these cpp(AppDelegate.cpp,HelloWorldScene.cpp) files.i know these files under “my_project_name\class” folder on the disk ,so i use “file~~>import~~>file system” to import the “class” folder to my project,and the cpp files in my project,but when i coding in “HelloWorldScene.cpp” file,it seems the file do not compile,someone knows?

You can refer HelloWorld/android/jin/helloworld/Android.mk, add pathes of .cpp files into it.

i got it,thanks:)

For more files is there script (cocos2dx\HelloWorld\android\jni\list.sh) for recursive cpp file listing.
