ASCSDK-------通用包接入文档（COCOS篇）-阿里云开发者社区

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。

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。
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。

#include "HelloWorldScene.h"

USING_NS_CC;

Scene* HelloWorld::createScene()
{
    // 'scene' is an autorelease object
    auto scene = Scene::create();
    
    // 'layer' is an autorelease object
    auto layer = HelloWorld::create();

    // add layer as a child to scene
    scene->addChild(layer);

    // return the scene
    return scene;
}

// on "init" you need to initialize your instance
bool HelloWorld::init()
{
    //////////////////////////////
    // 1. super init first
    if ( !Layer::init() )
    {
        return false;
    }
    
    Size visibleSize = Director::getInstance()->getVisibleSize();
    Vec2 origin = Director::getInstance()->getVisibleOrigin();

    auto bg = Sprite::create("HelloWorld.jpg");
    bg->setAnchorPoint(Vec2(0.5f, 0.5f));
    bg->setPosition(Vec2(origin.x + visibleSize.width / 2, origin.y + visibleSize.height / 2));
    bg->setScale(2.0f);
    this->addChild(bg);

    /////////////////////////////
    // 2. add a menu item with "X" image, which is clicked to quit the program
    //    you may modify it.

    // add a "close" icon to exit the progress. it's an autorelease object
    auto closeItem = MenuItemImage::create(
                                           "CloseNormal.png",
                                           "CloseSelected.png",
                                           CC_CALLBACK_1(HelloWorld::menuCloseCallback, this));
    
    closeItem->setPosition(Vec2(origin.x + visibleSize.width - closeItem->getContentSize().width/2 - 5.0f ,
                                origin.y + closeItem->getContentSize().height/2 + 5.0f));

    // create menu, it's an autorelease object
    auto menu = Menu::create(closeItem, NULL);
    menu->setPosition(Vec2::ZERO);
    this->addChild(menu, 1);

    this->labelUsername = Label::createWithTTF("ASCSDK", "fonts/Marker Felt.ttf", 24);
    
    // position the label on the center of the screen
    this->labelUsername->setPosition(Vec2(origin.x + visibleSize.width / 2,
        origin.y + visibleSize.height * 0.9 - this->labelUsername->getContentSize().height));

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_shared

LOCAL_MODULE_FILENAME := libcocos2dcpp

LOCAL_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.cpp

LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes

# _COCOS_HEADER_ANDROID_BEGIN
# _COCOS_HEADER_ANDROID_END


LOCAL_STATIC_LIBRARIES := cocos2dx_static

# _COCOS_LIB_ANDROID_BEGIN
# _COCOS_LIB_ANDROID_END

include $(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。
