无法使用 Mopub 在 android 中通过手动集成实现原生视频广告

Question

正如 Mopub 的文档所说的 here，集成了原生广告，然后是原生视频广告。

整合代码后，广告请求响应调用回调方法onNativeFail() 有一些回应

以下代码与工作流和 logcat 消息有关

公共类 MainActivity 扩展 Activity {

private MoPubView moPubView;
//private MoPubInterstitial mInterstitial;
private MoPubNative moPubNative;
private MoPubNativeNetworkListener moPubNativeNetworkListener;
private NativeAd.MoPubNativeEventListener moPubNativeEventListener;
AdapterHelper adapterHelper;
private NativeFullScreenVideoView nativeFullScreenVideoView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    moPubNativeNetworkListener = new MoPubNativeNetworkListener() {
        @Override
        public void onNativeLoad(NativeAd nativeAd) {
            Log.d("MoPub", "Native ad has loaded.");

        }

        @Override
        public void onNativeFail(NativeErrorCode errorCode) {
            Log.d("MoPub", "Native ad failed to load with error: " + errorCode.toString());
        }
    };

    moPubNativeEventListener = new NativeAd.MoPubNativeEventListener() {
        @Override
        public void onImpression(View view) {
            Log.d("MoPub", "Native ad recorded an impression.");
            // Impress is recorded - do what is needed AFTER the ad is visibly shown here.
        }

        @Override
        public void onClick(View view) {
            Log.d("MoPub", "Native ad recorded a click.");
            // Click tracking.
        }
    };

    moPubNative = new MoPubNative(this, "02a2d288d2674ad09f3241d46a44356e ", moPubNativeNetworkListener);

    ViewBinder viewBinder = new ViewBinder.Builder(R.layout.native_ad_list_item)
            .mainImageId(R.id.native_main_image)
            .iconImageId(R.id.native_icon_image)
            .titleId(R.id.native_title)
            .textId(R.id.native_text)
            .privacyInformationIconImageId(R.id.native_privacy_information_icon_image)
            .build();


    MediaViewBinder mediaViewBinder = new MediaViewBinder.Builder(R.layout.native_video_ad_layout)
            .mediaLayoutId(R.id.native_ad_video_view)
            .iconImageId(R.id.native_ad_icon_image)
            .titleId(R.id.native_ad_title)
            .textId(R.id.native_ad_text)
            .build();

    MoPubVideoNativeAdRenderer moPubVideoNativeAdRenderer = new MoPubVideoNativeAdRenderer(mediaViewBinder);
    moPubNative.registerAdRenderer(moPubVideoNativeAdRenderer);


    MoPubStaticNativeAdRenderer moPubStaticNativeAdRenderer = new MoPubStaticNativeAdRenderer(viewBinder);
    moPubNative.registerAdRenderer(moPubStaticNativeAdRenderer);


    EnumSet<RequestParameters.NativeAdAsset> desiredAssets = EnumSet.of(
            RequestParameters.NativeAdAsset.TITLE,
            RequestParameters.NativeAdAsset.TEXT,
            RequestParameters.NativeAdAsset.CALL_TO_ACTION_TEXT,
            RequestParameters.NativeAdAsset.MAIN_IMAGE,
            RequestParameters.NativeAdAsset.ICON_IMAGE,
            RequestParameters.NativeAdAsset.STAR_RATING
    );

    RequestParameters mRequestParameters = new RequestParameters.Builder()
            .desiredAssets(desiredAssets)
            .build();

    moPubNative.makeRequest();

}

}

运行此代码后，广告未加载，我的代码响应如下

Answer 1

根据他们的博客，以下情况不会出现广告：

这些错误表明您的广告单元没有填充。 没有广告网络会在 100% 的时间内填满，所以看到这个日志是正常的。新应用和容量非常低的应用往往会遇到较低的填充率。如果您对特定网络的填充有任何疑问，请联系您的广告网络代表。

如果您始终没有看到填充，请在 MoPub 用户界面的“网络”标签中查看您的广告网络展示位置详细信息，以及您在网络用户界面中的设置。

如果您忘记包含网络 SDK 或适配器文件，您将无法展示来自认证广告网络的广告。无法找到或实例化自定义事件和无法找到本机网络或自定义事件适配器日志消息指示网络 SDK 或适配器文件丢失、重命名或位于错误位置。

查看我们的集成第三方广告网络文档以解决此问题。
