ANR rate still increasing despite updating to latest AdMobSDK

[Marcin Małysz]

Hi 

I'm trying to find the reason of ANRs in our app as the threshold is very high 

We are using newest LTS Unity Version 2021.3.25f1

We have also integrated newest AdMobSDK 8.3.0

To make sure there are no other partner networks problem we have removed all mediation from our current build (so clean AdMobSDK only)

Also we incorporated all required flags like:

 <meta-data android:name="com.google.android.gms.ads.flag.OPTIMIZE_INITIALIZATION" android:value="true"/>
    <meta-data android:name="com.google.android.gms.ads.flag.OPTIMIZE_AD_LOADING" android:value="true"/>

Yet we still see same repeating ANR

Please assist what can we can do to minimize ANR on Admob setup.

Since I started using admob 8 years ago, on play store console under "Crashes & ANRs" I had millions of both crashes & anrs all related to gms dependency until version 22.0.0 not a single crash or anr after updating to 22.1.0 it started again not only crashes but on android 10 I have a interstitial ad after the splash it wouldn't load basically frozen on the splash so I downgraded to 22.0.0.

This worked for me to drastically reduce Crashes & ANRs:

AndroidManifest:

    <application

        <uses-library
            android:name="org.apache.http.legacy"
            android:required="false" />

    </application>

app build gradle:

    defaultConfig {

    useLibrary 'org.apache.http.legacy'

Hello Ronald Dwk,

You've mentioned that you were experiencing crashes and unexpected behavior when you were using version 22.1.0 of the SDK, would it be possible to provide the following so we may be able to investigate this:

• Sample App
• Steps to replicate
• App ID
• Complete Stack Trace Error
• Device name and versions affected
• Screen Recording

You can provide the following details via reply privately to author option or directly provide it to the link below.

If the file(s) you are looking to share are less than 25mb in total you can attach them to this case on your next reply. If you are having trouble attaching your file to this case or if your file(s) are larger than 25mb, you can share your files with me by performing the following steps:

Hi Marcin,

Thanks for reaching out to the GMA SDK Forum.

I understand that you already have tried to follow guide here https://developers.google.com/admob/android/optimize-initialization but still ANR persists.

However, you may try steps below:

• Install latest Unity 2022.3 LTS release in your app
• Use Google Mobile Ads Android SDK 22.1.0

If the issue still persists after doing the recommendation above, you may provide us the following details via "Reply Privately to Author" option:

1. Are there factors that cause this to happen more frequently?
2. Does this happen in our Sample apps?
3. Could you give us steps to replicate this ANR?
4. App ID
5. Ad Unit ID
6. Full stack trace of the crash logs (text copy)
7. Affected devices
8. percentage occurrence of the crash

If the file(s) you are looking to share are less than 25mb in total you can attach them to this case on your next reply. If you are having trouble attaching your file to this case or if your file(s) are larger than 25mb, you can share your files with me by performing the following steps:

Hi,
We also get many of these ANRs, and they increase with every new AdMob version :-(

The Play Console shows us logs like the following for initialization and ad loading (Banner, Interstitial, and Rewarded). We do not use any other mediation networks, and also OPTIMIZE_INITIALIZATION and OPTIMIZE_AD_LOADING do not help.

Now we can reproduce it on an Android Go device locally, and we figured out that this only happens when we use the Release build. On a Debug build, everything works fine without ANRs.

Hi

Yes we already tried the optimize initialization and as we are using Unity SDK 8.3.0 for AdMob we are targeting Google Mobile Ads Android SDK 22.1.0 we will update to latest Unity LTS version soon. 

I'm attaching the full ANR log from Crashlytics 

Thanks!

Hi Marcin,

Thank you for your response.

Let me share this to the wider team to further investigate this ANR. We will update you once we have more information.

Hello Marcin,

Thank you for waiting. Our team has completed the investigation and it appears that the ANR happened when the main thread is executing native code, which is out of GMA SDK's control. The GMA SDK is just happened to be on the main thread, which is one of the many calls that needs the JNI to translate Android to c#.

These ANR is probably on the Unity engine side, as there are other similar ANRs reported from external links: https://forum.unity.com/threads/anr-il2cpp-com-unity3d-player-reflectionhelper-nativeproxyinvoke.1012210/. We recommend reaching out to Unity's support team instead for further assistance.
