ANR happened on loading RewardedInterstitialAd

[Benjamin Cheng]

Hi,

We're facing this ANR after another Admob ANR have been resolved. They are reported in multiple terms. We currently can't reproduce the ANR locally, so we attached the logs from the Google Play console. It looks like the ANR occurred while loading the RewardedInterstitialAd. Could you please help to check and assist us how to get rid of this ANR? Thank you!

The ANR rate would be around 1% and it happened on devices across Android 6, 7.x, 8.x, 9, 10, 11 platforms. It seems that it's a general issue which didn't occur on specific brand of devices

The library version we are using is :

implementation 'com.google.android.gms:play-services-ads:19.8.0'

Hi,

Sorry! I don't have the sample app to reproduce this issue. However, I got more useful log and found that the ANR could be caused by the deadlock. We loaded some ads in the background thread and it seemed that they were blocked by com.android.webview.chromium.WebViewChromiumFactoryProvider.getStatics() call. We've modified our code to load all the ads in the same thread and wait for the next release to verify if it get resolved. Would that help to investigate this issue?

Hi Benjamin,

Thank you for your response.

Since you mentioned that your are getting blocked by the chromium web view, it seems that the issue may occur in chromium side. With that, you may want to file a bug Chromium for the crashes. Kindly inform us also once your'e updated code is release if you still encounter this issue.
