Android Admob不加载广告

广告不会加载，也不会显示在我的应用程序中。我尝试为应用程序创建另一个admob密钥，但没有帮助。此错误显示在logcat中：

W/Ads：获得广告回复时出现问题。错误代码：0 带广告：无法加载广告：0

    InterstitialAd mInterstitialAd;
    @Override
    protected void onCreate (Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

      MobileAds.initialize(getApplicationContext(), Parameters.ADS_KEY_ADMOB);
      mInterstitialAd = new InterstitialAd(this);
      mInterstitialAd.setAdUnitId(Parameters.ADMOB_ID_BLOCK);
      mInterstitialAd.setAdListener(new com.google.android.gms.ads.AdListener() {
         @Override
         public void onAdClosed() {
            requestNewInterstitial();
         }
      });
      requestNewInterstitial();


    RelativeLayout layout = new RelativeLayout(this);


    AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
    GameMain game = new GameMain(this);


    View gameView = initializeForView(game, config);

    layout.addView(gameView);


    setContentView(layout);


    }
    private void requestNewInterstitial() {
       AdRequest adRequest = new AdRequest.Builder()
            .build();
      mInterstitialAd.loadAd(adRequest);
     }

    public void showInterstitial(){
    runOnUiThread(new Runnable() {
      @Override public void run() {
         if (mInterstitialAd.isLoaded()) {
            mInterstitialAd.show();
         }
      }
    });
    }

同时，测试广告通常显示

给它一些时间。。。在真正的广告开始出现之前需要一些时间。。。显示测试广告意味着您的代码正常。。确保您在代码广告中使用了正确的横幅/间隙ID，并且在3天内未显示。您是否设置了正确的ID？确保您没有使用帐户ID。。同时登录您的Admob帐户，确保已填写所有注册信息（付款信息、税务信息等），并且帐户处于活动状态。。如果以上所有步骤都正确。。写信给admob，他们将指导您进一步使用

.addTestDevice（AdRequest.DEVICE\u ID\u EMULATOR）测试您的广告投放情况？
