cocos2dx-3.1 接入多盟广告sdk+Android (2)

上篇，把基本工作做完了，接下来，在C++下添加代码。

1、打开win32下的工程，添加一个类，DomobAd，代码如下，

<pre name="code" class="cpp">#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
#include <jni.h>
#include "platform/android/jni/JniHelper.h"
//#include <android/log.h>
#include "cocos2d.h"
#endif
using namespace cocos2d;
class DomobAd
{
public:
	DomobAd();
	virtual ~DomobAd();
	
	static void showInterstitial();
	/*static void initInterstitial();
	static void showBanner();
	static void hideBanner();*/
};

#include "DomobAd.h"
DomobAd::DomobAd(){}
DomobAd::~DomobAd(){}
//void DomobAd::showBanner()
//{
//#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID) 
//	JniMethodInfo showBanner;
//	bool isHave = JniHelper::getStaticMethodInfo(showBanner,"org/cocos2dx/cpp/AppActivity","showBannerStatic","()V");
//	if (!isHave) {
//		CCLog("jni:showBannerStatic false");
//	}
//	else{
//
//		showBanner.env->CallStaticVoidMethod(showBanner.classID,showBanner.methodID);
//	}
//#endif
//}
//void DomobAd::hideBanner()
//{
//#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID) 
//	JniMethodInfo hideBanner;
//	bool isHave = JniHelper::getStaticMethodInfo(hideBanner,"hideBannerStatic","()V");
//	if (!isHave) {
//		CCLog("jni:hideBannerStatic false");
//	}
//	else{
//		CCLog("jni:hideBannerStatic true");
//
//		hideBanner.env->CallStaticVoidMethod(hideBanner.classID,hideBanner.methodID);
//	}
//#endif
//}

void DomobAd::showInterstitial()
{
#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID) 
	JniMethodInfo showInterstitial;
	bool isHave = JniHelper::getStaticMethodInfo(showInterstitial,"showInterstitialStatic","()V");
	if (!isHave) {
		CCLog("jni:showInterstitial false");
	}
	else{
		CCLog("jni:showInterstitial true");

		showInterstitial.env->CallStaticVoidMethod(showInterstitial.classID,showInterstitial.methodID);
	}
#endif
}

//void DomobAd::initInterstitial()
//{
//#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID) 
//	JniMethodInfo initInterstitial;
//	bool isHave = JniHelper::getStaticMethodInfo(initInterstitial,"initInterstitialStatic","()V");
//	if (!isHave) {
//		CCLog("jni:initInterstitial false");
//	}
//	else{
//		CCLog("jni:initInterstitial true");
//
//		initInterstitial.env->CallStaticVoidMethod(initInterstitial.classID,initInterstitial.methodID);
//	}
//#endif
//}

</pre><pre name="code" class="cpp">

//在helloworldscene.cpp添加如下代码即可：

<pre name="code" class="cpp"> CCMenuItemLabel  * closeInterstital=CCMenuItemLabel::create(CCLabelTTF::create("showInterstital","Helvetica",40),this,menu_selector(HelloWorld::menuShowInterstitialCallback));

void HelloWorld::menuShowInterstitialCallback(cocos2d::CCObject* pSender){
