在模拟器中加载插页式广告时出现 AdMob 错误

Question

当我尝试加载插页式广告时，出现以下错误：

我用来请求插页式广告的代码就在我用来请求横幅广告（有效）的代码下方：

// Ads...
AdView mAdView = (AdView) findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);

// Create the interstitial.
interstitial = new InterstitialAd(this);
//interstitial.setAdUnitId(AdRequest.DEVICE_ID_EMULATOR);
// Create ad request.
AdRequest adRequestI = new AdRequest.Builder().addTestDevice("B3EEABB8EE11C2BE770B684D95219").build();
// Begin loading your interstitial.
interstitial.loadAd(adRequestI);

第 97 行是上例中的最后一行。我试过使用 interstitial.setAdUnitId(AdRequest.DEVICE_ID_EMULATOR) 而不是 addTestDevice，它不会引发错误，但也不会加载插页式广告。

Answer 1

您在设置 ID 之前加载您的广告：

AdRequest adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);// <-- Here

删除第一个调用，这样你会得到：

// Create the interstitial.
interstitial = new InterstitialAd(this);
//interstitial.setAdUnitId(AdRequest.DEVICE_ID_EMULATOR);
// Create ad request.
AdRequest adRequestI = new AdRequest.Builder().addTestDevice("B3EEABB8EE11C2BE770B684D95219").build();
// Begin loading your interstitial.
interstitial.loadAd(adRequestI);

此外还有这个方法：

// Invoke displayInterstitial() when you are ready to display an interstitial.
  public void displayInterstitial() {
    if (interstitial.isLoaded()) {
      interstitial.show();
    }
  }

Answer 2

您必须在加载前设置 AdUnitId Ads

    mAdView = (AdView)findViewById(R.id.adView);
    mAdView.setAdSize(AdSize.SMART_BANNER);
    mAdView.setAdUnitId("ca-app-pub-160126019342****/405183****");
    AdRequest.Builder adRequestBuilder = new AdRequest.Builder();
    adRequestBuilder.addTestDevice("B3EEABB8EE11C2BE770B684D95219ECB");

    mAdView.loadAd(adRequestBuilder.build());
