JNI调用

/*Java调用C++(就是讲Java中某个static native void 函数在C++中实现一下，然后在Java类中调用)*///在C++中对Java文件的private static native void getStone();方法实现为:#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID) //判断当前是否为Android平台 extern "C"{void Java_com_qingxue_game_GunStreet_getStone(JNIEnv*  env, jobject thiz){CCLog("Java_com_qingxue_game_GunStreet_getStone");_gameScene->_panelLayer->leavedStoneNum += 15;const char* LeavedStoneNum = ((CCString*)_gameScene->chnStrings->objectForKey("leavedStoneNum"))->m_sString.c_str(); _gameScene->_panelLayer->leavedStoneLabel->setString(CCString::createWithFormat("%s: %d",LeavedStoneNum, _gameScene->_panelLayer->leavedStoneNum)->getCString());}}#endif /*C++调用java*///头文件#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID) #include <jni.h> #include "platform/android/jni/JniHelper.h" #include <android/log.h> #endif //void GameScene::buyStone(){if(!
