Describe the problem

Steps to reproduce:

I build a project using Admob, it works fine with test app id, ad unit id. But when I release the app, no ads are shown. I test my application using LogCat, it shows these errors.

Relevant Code:

When App start this error is displayed in LogCat

我也有这个问题，蹲一手

Aseim99 · 2022-12-30T10:38:58Z

Hi, I have the same problem. Test ads work fine on editor but nothing happens on the mobile device (via apk).
"15938 15986 Error Unity AndroidJavaException: java.lang.ClassNotFoundException: com.google.android.gms.ads.AdSize"

Anyone got any solution? I have tried resolve and force resolve for android.

SYRollingStone · 2022-12-30T11:46:55Z

我将Gradle版本升级到6.9.x，并且重新修复了网络环境后，这个问题解决了。

Wondering, i have excluded the last line '-dontobfuscate', that doesn't matter right? Coz i think to keep the 'Obfuscate' feature.

NVentimiglia · 2023-01-18T01:43:02Z

This issue is often related not running the dependency manager before building.

In the Unity editor, select Assets > External Dependency Manager > Android Resolver > Resolve. The Unity External Dependency Manager library will copy the declared dependencies into the Assets/Plugins/Android directory of your Unity app.

Yes, me too. Everything is fine

Since there were no recent activities for this issue, we are therefore reluctantly going to close this bug for now.

If you are still experiencing the problem, please file a new issue with the same description, what happens and system / network tracing / Charles logs.

All system setups can be slightly different, so it's always better to open new issues and reference the related ones. Thanks for your contribution.

Unchecking "Use R8" from Edit->Project Settings->Publishing Settings under "Minify" solved this for me.
FYI I still have "Release" checked.

If you've followed the above solutions and the problem persists in Unity 2021.3.35, you can try disabling the main Gradle template. When prompted with the following message, click 'Disable'.
