广告请求成功，但由于缺少广告资源而没有返回广告 [英] Ad request successful, but no ad returned due to lack of ad inventory

问题描述

我刚接触 AdMob.起初，我试图用不同类型的广告创建一个测试应用程序.我使用真实的 ad_unit_id 和 nexus 4 进行测试.

I new in AdMob. At first I'm trying to create a test app with different types of ad. I use real ad_unit_id and nexus 4 for testing.

我为所有活动使用 1 个布局 xml:

I use 1 layout xml for all activity:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
    android:id="@+id/empty_layout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
</LinearLayout>

当我使用横幅广告创建简单的活动时，它工作正常.活动代码:

When i create simple activity with banner ad it's work fine. Activity code:

public class AdBannerActivity extends Activity {

    private AdView adView;

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

        adView = new AdView(this, AdSize.SMART_BANNER, getString(R.string.adUnitId));
        adView.setAdListener(this);

        LinearLayout layout = (LinearLayout) findViewById(R.id.empty_layout);

        layout.addView(adView);

        adView.loadAd(new AdRequest());
    }

    @Override
    public void onDestroy() {
        if (adView != null) {
            adView.destroy();
        }
        super.onDestroy();
    }
}

当我尝试使用全屏广告创建活动时，出现错误消息:

When i try to create activity with full screen ad, i have error message:

Ad request successful, but no ad returned due to lack of ad inventory.

活动代码:

public class AdInterstitialActivity extends Activity implements AdListener {

    private InterstitialAd interstitial;

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

        interstitial = new InterstitialAd(this, getString(R.string.adUnitId));

        interstitial.setAdListener(this);

        AdRequest adRequest = new AdRequest();

        interstitial.loadAd(adRequest);
    }

    @Override
    public void onReceiveAd(Ad ad) {
        if (ad == interstitial) {
            interstitial.show();
        }
    }

    @Override
    public void onDismissScreen(Ad ad) {
    }

    @Override
    public void onFailedToReceiveAd(Ad ad, ErrorCode error) {
        Log.e("AdTest", "Error code: " + error);
    }

    @Override
    public void onLeaveApplication(Ad ad) {
    }

    @Override
    public void onPresentScreen(Ad ad) {
    }
}

我做错了什么?如何解决这个问题?

What am I doing wrong? How to solve this problem?

解决方案:为 AdMob 帐户中的插页式广告创建新的 ad_unit_id.

Solution: Create new ad_unit_id for interstitial ads in AdMob account.

推荐答案

如果你有那个错误，那么你的代码是正确的.Admob 没有为您的应用展示任何广告(您所在的国家/地区，您的广告类型是决定因素).

If your have that error, then your code is correct. Admob just doesn't have any ads to display for your app (your country, your type of ads are determinants).

如果您想在测试模式下测试广告的行为，您应该查看此链接:

If you want to test the behavior of your ads in test mode, you should take a look at this link :

https://developers.google.com/mobile-ads-sdk/docs/admob/additional-controls#testmode

如果您刚刚创建了 Admob 帐户，则可能需要一些时间和一些请求来投放第一批广告.我在某处看到人们通过使用自定义横幅大小也有这个错误，所以一定要检查:

EDIT : If you have just created your Admob account, it may take some times and some requests to deliver the first ads. I saw somewhere that people had this error too by using custom size for banner, so be sure to check :
