ANR related to chromium-TrichromeWebViewGoogle.aab-stable-<US_SOCIAL_SECURITY_NUMBER>

[Dror Cohen]

Hi there,

I'm getting ANRs related to "chromium-TrichromeWebViewGoogle.aab-stable-<US_SOCIAL_SECURITY_NUMBER> - org.chromium.android_webview.AwContents.m"

Sometimes there's a stack trace like the following that appears to be originating from AdMob:

#00 pc 0x000000000001f0ac /system/lib64/libc.so (syscall+28) #01 pc 0x00000000000d7224 /system/lib64/libart.so (art::ConditionVariable::WaitHoldingLocks(art::Thread*)+148) #02 pc 0x000000000051bd30 /system/lib64/libart.so (art::GoToRunnable(art::Thread*) (.llvm.<US_SOCIAL_SECURITY_NUMBER>)+480) #03 pc 0x000000000051bb0c /system/lib64/libart.so (art::JniMethodEnd(unsigned int, art::Thread*)+28) at android.os.BinderProxy.transactNative (Native method)

This Binder call may be taking too long, causing the main thread to wait, and triggering the ANR

I'm using Unity 2021.3.21f Google Mobile Ads Unity Plugin v8.2.0, and have all optimization options turned on.This error has been reported on both Android 9.0 and Android 12.These ANRs originating from AdMob makes my app cross the bad behavior threshold on PlayStore, so resolving them will be greatly appreciated.

Thank you.

Providing a sample app will not be possible, and steps to replicate are also not applicable.

The app id is: com.tinkerlabs.power.inc.idle

This is the complete stack trace of the ANR I received from Google Play:

In the last 28 days, errors that are related to "chromium-TrichromeWebViewGoogle.aab-stable-<US_SOCIAL_SECURITY_NUMBER>" have been reported: 3 days ago, 4 days ago and 7 days ago.

I'm also getting a lot of separate ANRs related to "com.google.android.gms.policy_ads_fdr_dynamite" if that helps.

Thank you.

Hello,

Thank you for the additional information.

Before we forward this information to our wider team for further investigation, are you using any Mediation networks? If so, kindly share.

[Dror Cohen]

Hi, I'm not using any mediation networks.

Thank you.

[Mobile Ads SDK Forum Advisor]

Hi,

Thank you for your response.

Can you confirm first if you have tried to optimize initialization and ad loading (https://developers.google.com/admob/unity/optimize-initialization)? Asking this helps to improve the overall responsiveness of ads and help prevent "Application Not Responding" (ANR) (https://developer.android.com/topic/performance/vitals/anr) errors on your app. If you already tried this and ANR is still occurring, kindly let us know so we can share it to the wider team.

[Dror Cohen]

Thank you. I confirm I have already had these options turned on.

For now I have limited my marketing only to devices with Android 12+ which seems to have improved the situation. Nevertheless, I would prefer not to limit my marketing audience to only those with Android 12+, and of course devices with an older Android version who'd get my game through other means might increase my ANR rate again.

Thank you.

I am also facing a similar issue. I have enabled the manifest flags for optimization for ad load and  sdk inititialization. Any update here? Using Admob 22.1.0

I am not able to reproduce this issue while debugging, so I will not be able to provide a sample. However, the package name is com.english.listeningandspeaking.
