广告请求成功，但由于缺少广告资源而没有返回广告

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 :
