java - 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直接位于我用来请求横幅广告的代码下方(有效):

// 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。我尝试使用 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。

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();
    }
  }
