How can I compile the new files which added into extensions for android?

Hi… developers.
I have meet a problem during compiling my project for android app.
I needed to implement the functionality similar to UISwipeGestureRecognizer’s one, so I used the cocos2dx-extensions which uploaded by Artavazd Barseghyan, https://github.com/spalx/cocos2d-x-extensions.

Then, I integrated it successfully for iOS app, but for android when I was compiling that project, I saw the error message as below:

On Command Prompt:
# ./build_native.sh
///////////////////////////////////////////////////////////////////////////////////////
[armeabi] Compile++ thumb: game_shared <= GameScene.cpp

make: Leaving directory `/Volumes/Data/Applications/cocos2d-x-2.1.5/FlowBridges/proj.android’
/////////////////////////////////////////////////////////////////////////////
For iOS, I copied the CCGestureRecognizer’s .cpp files and .h files into the directory of extensions of my game directory.
$(my game directory)/libs/extensions/CCGestureRecognizer/

Who can you help me?
