廣告請求成功，但由於缺少廣告資源而沒有返回廣告

我是AdMob中的新成員。起初我試圖用不同類型的廣告創建測試應用程序。我使用真正的ad_unit_id和nexus 4進行測試。廣告請求成功，但由於缺少廣告資源而沒有返回廣告

我用1對佈局XML進行的所有活動：

<?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>

當我創建橫幅廣告簡單的活動它的做工精細。活動代碼：

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(); 
    } 
}

當我嘗試創建一個全屏的廣告活動，我已經錯誤消息：

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

活動代碼：

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) { 
    } 
}

我在做什麼錯？如何解決這個問題？

解決方案：爲AdMob帳戶中的插頁式廣告創建新的ad_unit_id。
