• 先说下大体的思路。和之前说的在Unity中接入ASCSDK一样，在Cocos2dx中接入ASCSDK,我们也分为两步，一个Android中的部分，另 一个是Coccos2dx中的部分。同时，我们希望尽可能地封装不同平台之间数据的传递，以及接口的调用。使得大部分游戏基于这个封装，都可以最快地速度来完成ASCSDK的接入。

1. 新建一个Android工程，作为ASCSDK和Cocos2dx的一个中间工程（ASCSDK_Cocos2dx），主要负责ASCSDK的接口调用封装，参数传递和解析等。这个工程，对于所有游戏都试用。
2. 在Cocos2dx中封装JNI调用，以及和Android中交互的数据格式等的定义和解析。同样地，这部分对于所有游戏也都适用。游戏中只需要调用这里提供的相关接口，以及实现相应的回调即可完成接入。

• 首先， 我们使用cocos new 新建一个Cocos2dx（我这里使用的是Cocos2dx 3.10版本）工程，名为Cocos_Demo。
• 目录如下图
  
• demo中我们创建了5个按钮，分别为登陆，支付，评价，展示横幅，展示插屏。代码以及运行效果如下。

{// 'scene' is an autorelease objectauto scene = Scene::create();// 'layer' is an autorelease objectauto layer = HelloWorld::create();// add layer as a child to scenescene->addChild(layer);// return the scenereturn scene;
}// on "init" you need to initialize your instance
bool HelloWorld::init()

}void HelloWorld::menuCloseCallback(Ref* pSender)
{Director::getInstance()->end();#if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)exit(0);
#endif
}

• 说明：

  • HelloWorldScene.cpp中init方法的最后，我们调用ASCSDK的初始化方法：
    ASCSDKInterface::getInstance()->initSDK(this);

• 实现回调接口

void HelloWorld::OnInitSuc()
{CCLOG("SDK初始化成功...");//一般不需要做什么处理
}void HelloWorld::OnLoginSuc(ASCLoginResult* result)
{CCLOG("SDK登录并认证成功...%s",result->userId.c_str());this->labelUsername->setString(result->sdkUsername);if (result->isSwitchAccount){//TODO:这里退回到登录界面，并且SDK是已经登录成功状态，不用再弹出SDK的登录界面}else{//TODO:登录认证成功，获取服务器列表，进入游戏服...}
}void HelloWorld::OnSwitchLogin()
{CCLOG("切换帐号成功...");//TODO:退回到登录界面，并弹出SDK登录界面(调用ASCSDKInterface::getInstance()->login())
}void HelloWorld::OnLogout()
{CCLOG("SDK帐号退出成功...");this->labelUsername->setString("ASCSDK");//TODO:退回到登录界面，并弹出SDK登录界面(调用ASCSDKInterface::getInstance()->login())
}

• 登陆以及支付以及广告调用，回调方法，具体调用，请参考demo。

3.将Cocos_Demo生成proj.android导入到eclipse中，然后将ASCSDK3和ASCSDK_Cocos2dx工程生成的jar包（分别是ascsdk2.jar和ascsdk_cocos2dx.jar）拷贝到HelloCocos安卓工程的libs目录下以及一些外部jar。然后，将生成的 AppActivity.java，本来是继承Cocos2dxActivity的，改为继承ASCCocosActivity。
同时，将AndroidManifest.xml中的application节点中，加上android:name=”com.ascsdk.ASCApplication”

• 目录如图
  
• AndroidManifest.xml内容

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.asc.sdk.demo.cocos"android:versionCode="1"android:versionName="1.0"android:installLocation="auto"><uses-sdk android:minSdkVersion="19"/><uses-feature android:glEsVersion="0x00020000" /><application android:label="@string/app_name"android:icon="@drawable/icon"android:name="com.asc.sdk.ASCApplication" ><!-- Tell Cocos2dxActivity the name of our .so --><meta-data android:name="android.app.lib_name"android:value="cocos2dcpp"/><activity android:name=".AppActivity"android:label="@string/app_name"android:screenOrientation="portrait"android:theme="@android:style/Theme.NoTitleBar.Fullscreen"android:configChanges="orientation|keyboardHidden|screenSize"><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity></application><supports-screens android:anyDensity="true"android:smallScreens="true"android:normalScreens="true"android:largeScreens="true"android:xlargeScreens="true"/><uses-permission android:name="android.permission.INTERNET"/>
</manifest>

• 最后，为了能够在Android中编译并运行，我们还需要将ASCSDK包含的这些Cpp文件，添加到Android.mk中，最终的文件如下：

LOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)$(call import-add-path,$(LOCAL_PATH)/../../cocos2d)
$(call import-add-path,$(LOCAL_PATH)/../../cocos2d/external)
$(call import-add-path,$(LOCAL_PATH)/../../cocos2d/cocos)LOCAL_MODULE := cocos2dcpp_sharedLOCAL_MODULE_FILENAME := libcocos2dcppLOCAL_SRC_FILES := hellocpp/main.cpp \../../Classes/AppDelegate.cpp \../../Classes/HelloWorldScene.cpp \../../Classes/jansson/value.c \../../Classes/jansson/utf.c \../../Classes/jansson/strconv.c \../../Classes/jansson/strbuffer.c \../../Classes/jansson/pack_unpack.c \../../Classes/jansson/memory.c \../../Classes/jansson/load.c \../../Classes/jansson/hashtable.c \../../Classes/jansson/error.c \../../Classes/jansson/dump.c \../../Classes/NDKHelper/CallFuncNV.cpp \../../Classes/NDKHelper/NDKCallbackNode.cpp \../../Classes/NDKHelper/NDKHelper.cpp \../../Classes/ascsdk/ASCSDKData.cpp \../../Classes/ascsdk/ASCSDKNativeCallback.cpp \../../Classes/ascsdk/ASCSDKInterface.cppLOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes# _COCOS_HEADER_ANDROID_BEGIN
# _COCOS_HEADER_ANDROID_ENDLOCAL_STATIC_LIBRARIES := cocos2dx_static# _COCOS_LIB_ANDROID_BEGIN
# _COCOS_LIB_ANDROID_ENDinclude $(BUILD_SHARED_LIBRARY)$(call import-module,.)# _COCOS_LIB_IMPORT_ANDROID_BEGIN
# _COCOS_LIB_IMPORT_ANDROID_END

4.到这里，接入就算完成了。我们可以使用cocos compile -p android 命令来编译Android平台，之前的操作如果稍有不慎，这里编译的过程中，也许会遇到一些错误，不过，看着啥错误，一一解决即可。
