Answer 1

.h file

CCSprite* oyuncuBul;

.cpp file

oyuncuBul = CCSprite::create("oyuna-basla.png");
oyuncuBul->setPosition(ccp(150,260));
oyuncuBul->setTag(menuOyuncuBul);
this->addChild(oyuncuBul, 0); 





void MainMenu::ccTouchesBegan(cocos2d::CCSet* touches, cocos2d::CCEvent* event)
        {
    CCTouch *touch = (CCTouch*) (touches->anyObject());
    CCPoint point = touch->getLocationInView();
    point = CCDirector::sharedDirector()->convertToGL(point);



    CCRect rectOyuncuBul = oyuncuBul->boundingBox();

    if(rectOyuncuBul.containsPoint(point)){
        CCDirector::sharedDirector()->replaceScene(OyunMenu::scene());          
    }

You have to add this line in android.mk file of jni folder

../../Classes/OyunMenu.cpp

Just like i am added in my android.mk file

LOCAL_SRC_FILES := hellocpp/main.cpp\\

               ../../Classes/Menu/AppDelegate.cpp\
               ../../Classes/Menu/HelloWorldScene.cpp\
               ../../Classes/Menu/MyScene.cpp\
               ../../Classes/Menu/LoadingLayer.cpp\
               ../../Classes/UI/NewLayer.cpp\
               ../../Classes/UI/HelpLayer.cpp
