cocos2d-x学习笔记（五）接入百度联盟广告（Android横幅和插屏广告）
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-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <!-- 以下为可选权限 --> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /> <uses-permission android:name="android.permission.RECORD_AUDIO" /> <uses-permission android:name="android.permission.VIBRATE" /> <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="com.android.browser.permission.READ_HISTORY_BOOKMARKS" />
◆添加APPSID和AppActivity申明
<meta-data android:name="BaiduMobAd_APP_ID" android:value="dcd69c04" /> <meta-data android:name="BaiduMobAd_APP_SEC" android:value="dcd69c04" /> <activity android:name="com.baidu.mobads.AppActivity" android:configChanges="keyboard|keyboardHidden|orientation" />
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
private AdView adView;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setupAds();
}
private void setupAds() {
RelativeLayout layout = new RelativeLayout(this);
addContentView(layout, new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT));
adView = new AdView(this);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.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
public class ShowAdHelper {
private static Handler mHandler;
public static void init(Handler handler)
{
ShowAdHelper.mHandler = handler;
}
private static void showMyAd()
{
Message msg = 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
public static final int SHOW_AD = 0x0001; InterstitialAd interAd;
3、在类AppActivity中新建getInsertAd()方法初始化插屏广告
public InterstitialAd getInsertAd() {
final InterstitialAd interAd1 = new InterstitialAd(this);
interAd1.setListener(new InterstitialAdListener() {
@Override
public void onAdClick(InterstitialAd arg0) {
Log.i("InterstitialAd", "onAdClick");
}
@Override
public void onAdDismissed() {
Log.i("InterstitialAd", "onAdDismissed");
interAd1.loadAd();
}
@Override
public void onAdFailed(String arg0) {
Log.i("InterstitialAd", "onAdFailed");
}
@Override
public void onAdPresent() {
Log.i("InterstitialAd", "onAdPresent");
}
@Override
public void onAdReady() {
Log.i("InterstitialAd", "onAdReady");
}
});
interAd1.loadAd();
return interAd1;
}
4、创建Handler
private Handler aHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case SHOW_AD:
if (interAd.isAdReady()) {
interAd.showAd(AppActivity.this);
Log.d("LC", "show");
} else {
interAd.loadAd();
}
Log.d("LC", "not show");
break;
}
}
};
5、在onCreate加入代码
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.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
void BackgroundLayer::loadAndroidAd()
{
#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID) //判断当前是否为Android平台
JniMethodInfo minfo;
jobject jobj;
bool b = 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
