Hi Olexandr,

Thanks for the heads-up! I'll relay the crash logs to the rest of the team and we'll see what we can do.  In the meantime, if you have more information regarding the steps that lead to these crashes, that'd rock.

Unfortunately, I can provide precise information only about Crash 7

Application use 'com.google.android.gms:play-services-ads:8.4.0'

To load DFP ads:

        final AdLoader loader = new AdLoader.Builder(getService().getApplicationContext(), AD_UNIT_ID)

            .forCustomTemplateAd(AD_UNIT_TEMPLATE_ID, new NativeCustomTemplateAd.OnCustomTemplateAdLoadedListener() {

              @Override

              public void onCustomTemplateAdLoaded(final NativeCustomTemplateAd dfpCustomAd) {

                if (!subscriber.isUnsubscribed()) {

                  subscriber.onNext(dfpCustomAd);

                  subscriber.onCompleted();

                }

              }

            }, null)

            .withAdListener(new DreamAdListener(tabletState.getShortName() + " : " + AD_UNIT_ID) {

              @Override

              public void onAdFailedToLoad(int errorCode) {

                if (!subscriber.isUnsubscribed()) {

                  subscriber.onError(new DfpLoadingException(errorCode, getTarget()));

                }

              }

            })

            .build();

        PublisherAdRequest.Builder builder = new PublisherAdRequest.Builder();

        tabletState.addTargetingOptions(builder);

        loader.loadAd(builder.build());

And display it:

    NativeAd.Image image = keyprDfpAd.getImage(DFP_AD_IMAGE_ASSET);

    if (image == null) {

      getAnalytics().serverError("Tablet downloaded dfp ad without image asset. Ad should have image under \""

          + DFP_AD_IMAGE_ASSET + "\" key. Available asset keys: " + String.valueOf(dfpAd.getAvailableAssetNames()))

          .log();

      return;

    }

    

    ImageView promoImage = ...;

    promoImage.setImageDrawable(image.getDrawable());

    dfpAd.recordImpression();

    promoImage.setOnClickListener(new View.OnClickListener() {

      @Override

      public void onClick(View v) {

        dfpAd.performClick(DFP_AD_IMAGE_ASSET);

      }

    });

For Crashes 1 - 6 we use variety of google-ads versions from 6.x to 8.4.0

And simply show PublisherAdView:

  <com.google.android.gms.ads.doubleclick.PublisherAdView
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:gravity="center"
      android:background="@android:color/white"
      android:tag="ad"
      android:layerType="software"
      ads:adSizes="@string/banner_size"
      ads:adUnitId="@string/ad_banner_unit_id"/>

And PublisherInterstitialAd:

  public boolean showInterstitialAd(final Activity activity) {
    // Create the interstitial
    final PublisherInterstitialAd interstitial = new PublisherInterstitialAd(activity);
    interstitial.setAdUnitId(activity.getString(R.string.ad_interstitial_unit_id));

    // Set Ad Listener to use the callbacks below
    interstitial.setAdListener(new InterstitialAdListener(interstitial));

    try {
      // Begin loading your interstitial
      final PublisherAdRequest.Builder interstitialAdRequestBuilder = buildAdRequest();
      interstitial.loadAd(interstitialAdRequestBuilder.build());
      return true;
    } catch (final Throwable t) {
      //rooted device
      if (interstitial.getAdListener() != null) {
        interstitial.getAdListener().onAdFailedToLoad(AdRequest.ERROR_CODE_INTERNAL_ERROR);
      }
    }

    return false;
  }

Hi Olexandr,

Do you also have the versions of the local Google Play services on the devices for any of those crashes?

I also see Crash 7 in my crash logs. As far as I observed, this happens more frequently when I try to load more than 1 ad at the same time(I have a viewpager like a slider banner and I try to load more than 6 ads concurrently). Any progress on that issue?

[Vu Chau (Mobile Ads SDK Team)]

Hi Yasin,

Can you send us some code snippets?  If you are loading multiple ads in parallel, are you doing so on background threads?

[mmccl...@twobitlabs.com]

Seeing a crash similar to Crash 7 in Play Services 9.2.0. Not sure if this has any bearing, but we're also loading multiple ads. This crash was not occurring on 7.8.0.

I couldn't find a bug report for this issue. Am I missing it?

This appears to be the same issue: https://groups.google.com/forum/#!category-topic/google-admob-ads-sdk/jXQW4gwUEDs as the crash I just posted.

Hi Mark,

The one on the forum thread you linked is a different stack trace (Fatal Exception: java.lang.NullPointerException: Attempt to invoke interface method 'android.view.View xq.e()' on a null object reference).

Can you update to Google Play services v9.4.0, recompile your app, and report back on whether the crash should subside?  V9.4.0 has resolved a large number of this and similar crashes.

Hi Fabian,

Could you share some other details (which kind of ad you are using, which ad network, affected Android API versions, and devices et al.)?

Are you able to reproduce the crash locally or are you receiving those reports from your users?

Thanks,
