  <p>Everything work fine, but these PublishedAdView make my scrollview performance so slow . I load this ads in <code>onCreate</code> of Activity by normal way in <a href="https://developers.google.com/android/reference/com/google/android/gms/ads/doubleclick/PublisherAdView" rel="nofollow noreferrer">documentation</a>. Is there a way to overcome it? i'm out of ideas. this is how my activity looks like</p>
  
  <pre><code>@Override
      protected void onCreate(Bundle savedInstanceState) {
          DesignUtil.configureNoAppBarTheme(ReadActivity.this);
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_read);
  
  mPublisherAdViewInside = findViewById(R.id.ads_InsideMediumRectangle);
          mPublisherAdViewInside.loadAd(new PublisherAdRequest.Builder().build());
          mPublisherAdViewInside.setAdListener(new TribunAdListener(mPublisherAdViewInside));
  
  }
  </code></pre>
