谷歌廣告Admob在cocos2dx上通過回調實現底部Banner

首先說明我的開發平台,以免由於平台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包里面，這里給出百度雲下載地址，大家也可以使用官方提供的包。

下載包之后導入到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

 

• 

然后添加以下代碼到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-permission android:name="android.permission.INTERNET"/> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

然后打開下項目的java代碼的主Activity（這里是是AppActivity），新建項目是一個新建的空的java類，實現代碼如下：

到這里廣告窗口就已經准備好了，就是等cocos2dx 游戲主程啟動時調用就OK了。

在cocos2dx里面調用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！
