title: No fill from ad server
body: <p>I know this topic had been posted many times, but there's no REAL solution for this problem.</p>
  <p>Recently, in few apps, I've decided to make an update. It was a minor update changing library version (admob as well) to the latest ones. I've also changed targetSdkVersion from 25 to 26. After few days I've checked stats on admob and in all of these apps fill rate had gone down to 0! And the number of requests had gone up. For banners and interstitials. Other apps are unaffected.</p>
  <p>I thought there was some silly mistake, but I cannot find any issue in my code.</p>
  <p>In logs for the banner as well as for interstitial I'm seeing this:</p>
  <blockquote>
  <p>I/Ads: No fill from ad server.</p>
  <p>W/Ads: Failed to load ad: 3</p>
  </blockquote>
  <p>I've tried my best to simplify the problem, so I've created a brand new project from android studio template - Google AdMob Ads Activity and I've set package name to one of the affected apps. And the result is the same. Still no fill.</p>
  <ul>
  <li>I've tried adding device as a test device and this log</li>
  </ul>
  <blockquote>
  <p>This request is sent from a test device.</p>
  </blockquote>
  <p>is confirming this.</p>
  <ul>
  <li><p>I've tried using dummy ad ids from this post: <a href="https://stackoverflow.com/questions/12553929/is-there-any-admob-dummy-id/27390635#27390635">Is there any AdMob dummy id?</a></p>
  </li>
  <li><p>I've tried using different devices with different sdk level.</p>
  </li>
  <li><p>I've tried using firebase-ads as well as play-services-ads.</p>
  </li>
  <li><p>I've tried using older admob sdks.</p>
  </li>
  <li><p>I've tried using lower targerSdkVersions.</p>
  </li>
  </ul>
  <p>All of these gave me nothing. But I've found only one way to this: CHANGE PACKAGE NAME. Immediately, no matter what ad is was, and if it's a test device or not I'm always getting an ad. Interstitials and banners.</p>
  <p>Here's my MainActivity.java code:</p>
  <pre><code>public class MainActivity extends AppCompatActivity {
  
      public static final String ADMOB_INTERSTITIAL_DUMMY = &quot;ca-app-pub-3940256099942544/1033173712&quot;;
      public static final String ADMOB_INTERSTITIAL = &quot;ca-app-pub-my_own_ad_id&quot;;
      public InterstitialAd interstitial;
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
  
          AdView adView = (AdView) findViewById(R.id.adView);
          adView.loadAd(newAdRequest());
  
          interstitial = new InterstitialAd(this);
          interstitial.setAdUnitId(ADMOB_INTERSTITIAL_DUMMY); //ADMOB_INTERSTITIAL
          interstitial.loadAd(newAdRequest());
  
          interstitial.setAdListener(new AdListener() {
  
              @Override
              public void onAdClosed() {
                  super.onAdClosed();
                  interstitial.loadAd(newAdRequest());
              }
  
          });
  
          Button btnShowAd = (Button) findViewById(R.id.btnShowAd);
          btnShowAd.setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View view) {
                  if(interstitial != null){
                      if(interstitial.isLoaded()){
                          interstitial.show();
                      }
                  }
              }
          });
      }
  
      private static AdRequest newAdRequest() {
          AdRequest adRequest = new AdRequest.Builder()
                  .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
                  .addTestDevice(&quot;device_1&quot;)
                  .addTestDevice(&quot;device_2&quot;)
                  .addTestDevice(&quot;device_3&quot;)
                  .addTestDevice(&quot;device_4&quot;)
                  .build();
          return adRequest;

  <p>Could it mean that I've been banned? I didn't get any email from admob, haven't changed places where I display ads and also this happened for few apps at the same time, at the day I've updated them. In the past, I had similar issues, but it was just my devices that didn't get any fill rate, but it wasn't 0 worldwide and also it came back to normal after some time. But this case is different.</p>
  <p>I'm aware of this topic:</p>
  <p><a href="https://stackoverflow.com/questions/33566485/failed-to-load-ad-3">failed to load ad : 3</a></p>
  <p>But this is not a lack of ad inventory, it cannot go from 90% to 0% on few apps at the same time.</p>
