首先說明我的開發平臺,以免由於平臺問題造成不必要的誤解：
cocos2dx-3.4
ndk-r9d
eclipse
Admob是谷歌官方廣告，已經集成在google_play_service_lib包裏面，這裏給出百度雲下載地址，大家也可以使用官方提供的包。
下載包之後導入到eclipse，將剛導入的項目添加到自己的項目（本文中的項目是AdmobDemo）中做依賴，如下圖
然後添加以下代碼到AdmobDemo的Manifest.xml的<application>下：
<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version"/> <activity android:name="com.google.android.gms.ads.AdActivity" android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
添加以下權限到Manifest.xml的<manifest>標簽下：
<uses-permissionandroid:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
然後打開下項目的java代碼的主Activity（這裏是是AppActivity），新建項目是一個新建的空的java類，實現代碼如下：

}
到這裏廣告窗口就已經準備好了，就是等cocos2dx 遊戲主程啟動時調用就OK了。
在cocos2dx裏面調用Java需要使用Jni回調。
下面給出AdmobHelper.cpp類的實現：
#include "AdmobHelper.h" #include "cocos2d.h" bool AdmobHelper::isAdShowing = true; #if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID) #include "platform/android/jni/JniHelper.h" #include <jni.h> //#include <android/log.h> const char* AppActivityClassName = "org/cocos2dx/cpp/AppActivity"; void AdmobHelper::hideAd() { cocos2d::JniMethodInfo t; if (cocos2d::JniHelper::getStaticMethodInfo(t, AppActivityClassName, "hideAd", "()V")) { t.env->CallStaticVoidMethod(t.classID, t.methodID); t.env->DeleteLocalRef(t.classID); isAdShowing = false; } } void AdmobHelper::showAd() { cocos2d::JniMethodInfo t; if (cocos2d::JniHelper::getStaticMethodInfo(t, AppActivityClassName, "showAd", "()V")) { t.env->CallStaticVoidMethod(t.classID, t.methodID); t.env->DeleteLocalRef(t.classID); isAdShowing = true; } } #else void AdmobHelper::hideAd() { CCLOG("hideAd() called"); isAdShowing = false; return; //nothing } void AdmobHelper::showAd() { CCLOG("showAd() called"); isAdShowing = true; return; //nothing; } #endif
通過上面的AdmobHelper::showAd()就可以在C++代碼中調用廣告了，記得添加AdmobHelper.h到頭文件中哦。
是不是很簡單呢，自己實踐一遍吧！
此處給出在AdmobDemo在github上的地址：https://github.com/DiaoYung/AdmobDemo;各位可以按此方法添加到自己的項目中即可。博文寫的時候正在上傳代碼，天朝GitHub比較慢。
