cocos2d-x学习笔记（五）接入百度联盟广告（Android横幅和插屏广告）

2024-12-21 技术教程

用cocos2d-x 3.4 开发了个小游戏，然后成功的接入百度联盟的广告，很多初学者也希望在自己开发的游戏接入广告盈利，所以我就以百度联盟的横幅和插屏广告为例，根据自己接入的步骤做个总结，希望对有需要的开发者有所帮助。

一、百度SDK包导入与权限的配置

1、导入jar包

下载百度联盟android版的SDK包，我下载的文件名Baidu_Union_SDK_Android.zip，解压后文件夹里面有个jar包Baidu_MobAds_SDK.jar，将该jar包复制到你工程的libs目录下（如果没有新建一个libs文件夹），然后右键点击你的项目->Properties->Java Build Path->Libraries->Add JARs添加百度jar包，如下图所示：

2、配置AndroidManifest.xml

◆添加权限

<uses-permissionandroid:name="android.permission.INTERNET"/><uses-permissionandroid:name="android.permission.READ_PHONE_STATE"/><uses-permissionandroid:name="android.permission.ACCESS_NETWORK_STATE"/><uses-permissionandroid:name="android.permission.ACCESS_COARSE_LOCATION"/><uses-permissionandroid:name="android.permission.WRITE_EXTERNAL_STORAGE"/><uses-permissionandroid:name="android.permission.ACCESS_WIFI_STATE"/><uses-permissionandroid:name="android.permission.CHANGE_WIFI_STATE"/><uses-permissionandroid:name="android.permission.RECORD_AUDIO"/><uses-permissionandroid:name="android.permission.VIBRATE"/><uses-permissionandroid:name="android.permission.CAMERA"/><uses-permissionandroid:name="android.permission.ACCESS_FINE_LOCATION"/><uses-permissionandroid:name="com.android.browser.permission.READ_HISTORY_BOOKMARKS"/>

◆添加APPSID和AppActivity申明

如下图所示：

二、横幅banner广告的接入

在AppActivity.java文件中加入如下代码

privateAdViewadView;@OverrideprotectedvoidonCreate(BundlesavedInstanceState){//TODOAuto-generatedmethodstubsuper.onCreate(savedInstanceState);setupAds();}privatevoidsetupAds(){RelativeLayoutlayout=newRelativeLayout(this);addContentView(layout,newLayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT));adView=newAdView(this);RelativeLayout.LayoutParamslayoutParams=newRelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);layout.addView(adView,layoutParams);}

如图所示：

加入代码后广告会在游戏的底端显示

三、加入插屏广告

1、在类AppActivity同一包名下新建ShowAdHelper类文件

2、在类ShowAdHelper中加入如下代码

publicclassShowAdHelper{privatestaticHandlermHandler;publicstaticvoidinit(Handlerhandler){ShowAdHelper.mHandler=handler;}privatestaticvoidshowMyAd(){Messagemsg=mHandler.obtainMessage();msg.what=AppActivity.SHOW_AD;msg.sendToTarget();}}

3、在类ShowAdHelper中定义一个变量和一个常量

publicstaticfinalintSHOW_AD=0x0001;InterstitialAdinterAd;

3、在类AppActivity中新建getInsertAd()方法初始化插屏广告

publicInterstitialAdgetInsertAd(){finalInterstitialAdinterAd1=newInterstitialAd(this);interAd1.setListener(newInterstitialAdListener(){@OverridepublicvoidonAdClick(InterstitialAdarg0){Log.i("InterstitialAd","onAdClick");}@OverridepublicvoidonAdDismissed(){Log.i("InterstitialAd","onAdDismissed");interAd1.loadAd();}@OverridepublicvoidonAdFailed(Stringarg0){Log.i("InterstitialAd","onAdFailed");}@OverridepublicvoidonAdPresent(){Log.i("InterstitialAd","onAdPresent");}@OverridepublicvoidonAdReady(){Log.i("InterstitialAd","onAdReady");}});interAd1.loadAd();returninterAd1;}

4、创建Handler

privateHandleraHandler=newHandler(){@OverridepublicvoidhandleMessage(Messagemsg){switch(msg.what){caseSHOW_AD:if(interAd.isAdReady()){interAd.showAd(AppActivity.this);Log.d("LC","show");}else{interAd.loadAd();}Log.d("LC","notshow");break;}}};

5、在onCreate加入代码

@OverrideprotectedvoidonCreate(BundlesavedInstanceState){//TODOAuto-generatedmethodstubsuper.onCreate(savedInstanceState);interAd=getInsertAd();ShowAdHelper.init(aHandler);}

6、java层的编写就此结束了，接下去在C++层中通过jni调用ShowAdHelper类中的showMyAd函数

voidBackgroundLayer::loadAndroidAd(){#if(CC_TARGET_PLATFORM==CC_PLATFORM_ANDROID)//判断当前是否为Android平台JniMethodInfominfo;jobjectjobj;boolb=JniHelper::getStaticMethodInfo(minfo,"org/cocos2dx/cpp/ShowAdHelper","showMyAd","()V");jobj=minfo.env->CallStaticObjectMethod(minfo.classID,minfo.methodID);#endif}

同时在BackgroundLayer文件开头加入

#if(CC_TARGET_PLATFORM==CC_PLATFORM_ANDROID)#include<jni.h>#include"platform/android/jni/JniHelper.h"#endif

然后在所需显示插屏广告的地方调用loadAndroidAd()函数即可
