    Have you added the MyBodyParser files to your project?

    yes, i did it.

    in CMakeLists.txt file, ichange it 

    set(GAME_SRC
  Classes/AppDelegate.cpp
  Classes/HelloWorldScene.cpp
  Classes/MyBodyParser.cpp
  ${PLATFORM_SPECIFIC_SRC}
)

set(GAME_HEADERS
  Classes/AppDelegate.h
  Classes/HelloWorldScene.h
  Classes/MyBodyParser.h
  ${PLATFORM_SPECIFIC_HEADERS}
)

     

     

    and in Android.mk i add here

    LOCAL_SRC_FILES := hellocpp/main.cpp \
                   ../../Classes/AppDelegate.cpp \
                   ../../Classes/HelloWorldScene.cpp \
                   ../../Classes/HelloWorldScene.cpp

    yep.. was a stupid error.. >.< 

    well tnks for reply error fixed now.
