我最近实施了 admob 插页式广告，并将异常/错误作为构建请求 URL 的错误。来自方法 onAdFailedToLoad()，而且我的广告也没有显示。

我的代码：

InterstitialAd interstitialAd;
        protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
        
                InterstitialAd interstitialAd = new InterstitialAd(MainActivity.this);
                interstitialAd.setAdUnitId(KEY);
                MobileAds.initialize(MainActivity.this, new OnInitializationCompleteListener() {
                    @Override
                    public void onInitializationComplete(InitializationStatus initializationStatus) {
                        Log.e("app","MobileAds onInitializationComplete");
                    }
                });
                interstitialAd.loadAd(new AdRequest.Builder().build());
                interstitialAd.setAdListener(new AdListener(){
                    @Override
                    public void onAdLoaded() {
                        Log.e("app","ad loaded");
                    }
        
                    @Override
                    public void onAdFailedToLoad(LoadAdError loadAdError) {
                        Log.e("app","ad failedToLoad: "+loadAdError.getMessage()); //error/exception here
                    }
                });
}
                  protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        super.onActivityResult(requestCode, resultCode, data);
        if(interstitialAd.isLoaded()) {
                    interstitialAd.show();
                    Log.e("app","ad loaded"); …
