Googleads-mobile-unity: cannot resolve AndroidJavaException: java.lang.ClassNotFoundException: com.google.android.gms.ads.AdSize

[YashSOA]

Hi,

I am using version 3.7.1 of googleads mobile unity plugin downloaded from below URL for one of my game that i am developing in Unity.

URL : https://github.com/googleads/googleads-mobile-unity/releases
Version : 3.7.1

However, this doesn't work for me. When i tried to run the game and test out the ad, i am getting below error:

I/Unity﹕ AndroidJavaException: java.lang.ClassNotFoundException: com.google.android.gms.ads.AdSize

I am not sure what i am doing wrong, i tried to look into other open issues, but could not resolve my issue. I would appreciate if some one can guide/help me to resolve this issue.

Regards,

@YashSOA are you including the required Play Services AARs in your Unity project? If these AARs are not present in the Assets/Plugins/Android directory of your Unity project, perform dependency resolution by selecting Assets -> Play Services Resolver -> Android Resolver -> Resolve in the Unity Editor.

[YashSOA]

Thanks for the quick response. I checked the plugins/android and can see that there is no aar file present. I can see two errors in console window (attached the snap), maybe this is the reason why there is no aar present.

I am new to the gradle. Can you please suggest what can fix this issue?

[rampara]

Can you try navigating to the `C:\Users\dominic.gradle\wrapper\dists\gradle-3.2.1-bin\' directory and removing all of its contents before attempting dependency resolution again?

[YashSOA]

sure! giving it a try !

[YashSOA]

well, that worked! AAR files showed up in the folder , and when i build and run the game on my phone, test ads started coming up.

Appreciate your quick help on this. Thanks :+1: :100:

I would close this issue. Thanks for your help.
