Beginner Question: How to add new own files for compilation?

Hi all,

I’ve successfully compiled and run HelloWorld example, but when I want to extend it with my new source files, I cannot find the place where to add the to compilation - NDK build still builds only AppDelegate.cpp / HelloWorldScene.cpp

make: Entering directory `D:/Sedelnikov/Outworks/Book1/proj.android’
Gdbserver : [arm-linux-androideabi-4.6] libs/armeabi/gdbserver
Gdbsetup : libs/armeabi/gdb.setup
"Compile*+ thumb : game_shared <= AppDelegate.cpp
"Compile*+ thumb : game_shared <= HelloWorldScene.cpp

1º Go to path proj.android/jni
2º Open Android.mk
3º Add your own files to source.
