SDK初始化

简介

      在接入MG Ads SDK之前，首先需要进行SDK的初始化，初始化完成后，才可以配合后台系统使用本SDK的全部功能，在进入游戏后即进行SDK初始化。

SDK初始化

void InitMgAdSdk(HWND hWnd) {
    if (hDLL) return;

    hDLL = LoadLibrary(L"MgAdSDKCSharpDLL.dll");
    if (hDLL) {
        // Register the CMP callback event
        if (auto func = (CmpClosedEvent)GetProcAddress(hDLL, "CmpClosedEvent")) //CMP已关闭
            func(onCmpClosedEvent); 

        // Register the initialisation completion callback event
        if (auto func = (InitCompleteEvent)GetProcAddress(hDLL, "InitCompleteEvent")) // 初始化完成后的回调函数
            func(onInitCompleteEvent);
        if (auto func = (AdCloseEvent)GetProcAddress(hDLL, "AdCloseEvent")) //广告关闭事件的回调函数
            func(onAdCloseEvent);

        //1.设置参数
        setAppId(hDLL, YourAppId, YourSecretKey);

        //2.首先判断是否需要弹出CMP
        if (isOpenCmp(hDLL))
        { 
            RECT clientRect;
            if (GetClientRect(hWnd, &clientRect)) {
                int panelWidth = clientRect.right - clientRect.left;
                int panelHeight = clientRect.bottom - clientRect.top;

                //2.1.创建CMP容器
                HINSTANCE minstance = (HINSTANCE)GetWindowLongPtr(hWnd, GWLP_HINSTANCE);
                g_hPnlCmp = CreateWindowW(L"STATIC", L"This is a panel for CMP", WS_CHILD | WS_VISIBLE, 0, 0, panelWidth, 50, hWnd, (HMENU)3011, minstance, NULL);
                BringWindowToTop(g_hPnlCmp); 

                //2.2.弹出CMP
                nlohmann::json json_obj = {
                 {"handle", reinterpret_cast<int>(g_hPnlCmp)},
                 {"parentWidth", panelWidth},
                 {"parentHeight", panelHeight}
                };
                std::string jsonStr = json_obj.dump();
                openCmp(hDLL, jsonStr.c_str());
            }
        } 

        //3.SDK initialisation
        initialize(hDLL); 
    }
}

void initialize(HINSTANCE hdll) {
    try
    {
        Initialize func = (Initialize)GetProcAddress(hdll, "Initialize");
        func(YourAppId, YourSecretKey);
    }
    catch (const std::exception&)
    {
    }
}

//初始化完成的回调函数
void onInitCompleteEvent(char* s) {
    try
    {
        nlohmann::json json_obj = nlohmann::json::parse(s); //{"success":true,"data":""}
        bool success = json_obj["success"];
        if (success) {
            AppendLog(L"Initialization successful");

            //退屏广告；Step1.初始化成功之后，加载退屏广告资源
            setupExitAd(hDLL);

            //向UI线程发消息，使其调用开屏广告
            PostMessage(g_hwndMain, WM_SHOW_OPENSCREEN_ADVERT, 0, NULL);
        }
    }
    catch (const std::exception&)
    { 
    } 
}

void onCmpClosedEvent(char* s) {
    try
    {
        g_cmpChangedWidth = 0;
        g_cmpChangedHeight = 0;

        //在UI线程移除CMP控件
        PostMessage(g_hwndMain, WM_DESTROY_CMP, 0, NULL);

        AppendLog(L"CMP has been removed.");
    }
    catch (const std::exception&)
    {
    }
}

没有初始化成功的错误可能如下

● 网络故障，没有正确的网络支持

　　● UWP应用不支持VPN，本机开启了VPN软件

　　● AppId错误，请登录开发者后台检查应用设置

　　● 服务器问题，请检查result的错误信息，及时联系技术支持
