无法让MoPub向我的Android应用程序发送本机广告

我按照Mopub的说明在我的Android应用程序中实现了他们的原生广告

我检查了其他来源的代码，显然，一切似乎都正常，但实际上我无法让Mopub加载任何广告。我的代码是：

 SdkConfiguration sdkConfiguration = new SdkConfiguration
            .Builder("11a17b188668469fb0412708c3d16813") // trial #
            .build();
    MoPub.initializeSdk(this, sdkConfiguration, initSdkListener());

    MoPubNative moPubNative = new MoPubNative(this, "11a17b188668469fb0412708c3d16813", this); // 11a17b188668469fb0412708c3d16813

    ViewBinder viewBinder = new ViewBinder.Builder(R.layout.mopub_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();
    MoPubStaticNativeAdRenderer moPubStaticNativeAdRenderer = new MoPubStaticNativeAdRenderer(viewBinder);
    moPubNative.registerAdRenderer(moPubStaticNativeAdRenderer);

    EnumSet<RequestParameters.NativeAdAsset> desiredAssets = EnumSet.of( // Optional
            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();

以及mopubinal.makeRequest（）之后的MoPub本机变量的快照：
