Problem integrating AdMob plugin into my Unity Project

[Evangelos Oganesof]

Hi, I have to integrate AdMob into my Unity Project. 
I followed the steps of installing the latest unity package from the official guide, I did install GoogleMobileAds-v7.1.0.unitypackage then I installed GoogleMobileAds-Ad-Placements.unitypackage. I ran Resolve, Force Resolve, and Delete Resolved Libraries

then I did the GoogleMobileAdsSettings setup by enabling
Google AdMob Enabled = ✔ , AdMob App ID Android = "Filled with my app admob id"

then i went to my initializing script and added these lines of code 
/////////////////////////////////////////////////////

using GoogleMobileAds.Api;

void Start(){

AdModInit();

}

void AdModInit(){

         Status = "Initializing Ads Service";

         // Initialize the Google Mobile Ads SDK.

        MobileAds.Initialize(initStatus => {

            Status = "Ads Service is Initalized successfully";

            Ads_St = true;

         });

    }

////////////////////////////////////////////////////////

When I start Unity I get this error
Unloading broken assembly Assets/GoogleMobileAds/GoogleMobileAds.Unity.dll, this assembly can cause crashes in the runtime

When I build my project and run my game, at the initialization scene where the script is, the logcat outputs the following errors

 AndroidJavaException: java.lang.ClassNotFoundException: com.google.android.gms.ads.initialization.OnInitializationCompleteListener

Hi Evangelos, 

 

Did you try the steps I outlined in the previous email?

I was able to replicate the issue. Here is the fix:

- Delete the GoogleMobileAds plugin. This includes the /Plugin folder and the /GoogleMobileAds folder.
- Install the Ad Placements Beta.
- Do not install any additional plugins. The Ad Placements beta plugin includes all required dependencies.

Hope this helps,

Nick
