1. 引言

Cocos2d-x作为一款跨平台游戏开发引擎，在移动游戏开发中占据重要地位。随着游戏商业化需求的增长，集成第三方SDK（如广告、支付、分享）已成为游戏开发的必备环节。本文将全面介绍如何在Cocos2d-x项目中集成各类第三方SDK，提供从理论到实践的完整解决方案。

2. 技术背景

2.1 Cocos2d-x架构特点

跨平台性：支持iOS、Android、Windows等多平台
C++核心：基于C++开发，性能优异
JavaScript绑定：支持JS脚本开发
Lua绑定：支持Lua脚本开发

2.2 SDK集成挑战

平台差异：不同平台的SDK接口和实现方式各异
生命周期管理：需与Cocos2d-x的生命周期协调
线程安全：确保UI操作在主线程执行
内存管理：避免内存泄漏和资源冲突

3. 应用使用场景

3.1 广告场景

激励视频广告：观看完整视频获得游戏奖励
插屏广告：关卡切换或游戏结束时的全屏广告
横幅广告：常驻界面底部的广告条

3.2 支付场景

应用内购买：购买虚拟道具、金币等
订阅服务：会员特权、去广告等
一次性付费：解锁完整版游戏

3.3 分享场景

社交分享：分享游戏成绩到微信、微博
邀请好友：通过分享链接获取奖励
内容传播：分享游戏截图或视频

4. 环境准备

4.1 开发环境要求

# Cocos2d-x版本：v3.17+
# Android Studio：4.0+
# Xcode：11.0+
# NDK：r21e+
# Python：2.7.x (用于构建)

4.2 项目配置

下载Cocos2d-x引擎并配置环境变量
创建新项目：cocos new MyGame -p com.yourcompany.mygame -l cpp -d ~/projects
配置Android和iOS原生开发环境

5. 广告SDK集成（以AdMob为例）

5.1 原理概述

AdMob通过JNI桥接Android原生SDK和Cocos2d-x C++层，iOS则直接通过Objective-C++调用。

5.2 Android平台集成

5.2.1 添加依赖

在proj.android/app/build.gradle中添加：

dependencies {
    implementation 'com.google.android.gms:play-services-ads:20.6.0'
}

5.2.2 JNI接口定义

创建proj.android/app/src/org/cocos2dx/cpp/JniHelper.java的扩展：

package org.cocos2dx.cpp;

import android.app.Activity;
import android.util.Log;
import com.google.android.gms.ads.AdError;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.FullScreenContentCallback;

5.3 iOS平台集成

5.3.1 添加依赖

5.3.2 Objective-C++封装

创建proj.ios_mac/ios/AdMobBridge.h：

#import <Foundation/Foundation.h>
#import <GoogleMobileAds/GoogleMobileAds.h>

NS_ASSUME_NONNULL_BEGIN

6. 支付SDK集成（以Google Play Billing为例）

6.1 原理概述

Google Play Billing通过AIDL接口与Android应用交互，Cocos2d-x通过JNI桥接调用Java层API完成支付流程。

6.2 Android支付集成

6.2.1 添加依赖

在proj.android/app/build.gradle中添加：

dependencies {
    implementation 'com.android.billingclient:billing:5.0.0'
}

6.2.2 权限配置

在proj.android/app/src/main/AndroidManifest.xml中添加：

<uses-permission android:name="com.android.vending.BILLING" />

6.2.3 Java层支付逻辑

创建proj.android/app/src/org/cocos2dx/cpp/BillingManager.java：

7. 分享SDK集成（以ShareSDK为例）

7.1 原理概述

ShareSDK通过桥接各社交平台的原生SDK，提供统一的分享接口。Cocos2d-x通过JNI调用Java层的ShareSDK API完成分享功能。

7.2 Android分享集成

7.2.1 添加依赖

在proj.android/app/build.gradle中添加：

dependencies {
    implementation 'cn.sharesdk:ShareSDK:3.9.9' // 包含常用平台
    // 或者单独添加平台
    // implementation 'cn.sharesdk:ShareSDK-Wechat:3.9.9'
    // implementation 'cn.sharesdk:ShareSDK-Wechat-Favorite:3.9.9'
    // implementation 'cn.sharesdk:ShareSDK-QQ:3.9.9'
    // implementation 'cn.sharesdk:ShareSDK-QZone:3.9.9'
    // implementation 'cn.sharesdk:ShareSDK-SinaWeibo:3.9.9'
}

7.2.2 权限配置

在AndroidManifest.xml中添加：

<!-- 网络权限 -->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

<!-- 外部存储权限（可选，用于保存图片） -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

7.2.3 分享功能实现
