AdMob and custom Assemblies

Unity Engine

Hi,

I’ve been using custom assemblies through my project to make everything more modular and I had to in the past create assemblies of plugins as well. I tried to do the same for AdMob but I get the error below.

NullReferenceException: Object reference not set to an instance of an object
GoogleMobileAds.Api.MobileAds.GetMobileAdsClient () (at Assets/GoogleMobileAds/Api/MobileAds.cs:50)
GoogleMobileAds.Api.MobileAds..cctor () (at Assets/GoogleMobileAds/Api/MobileAds.cs:24)
Rethrow as TypeInitializationException: The type initializer for 'GoogleMobileAds.Api.MobileAds' threw an exception.
AdMobInitialize.Awake () (at Assets/BasicMobile/Scripts/Ads/AdMobInitialize.cs:20)

Deleting all the assemblies resolves the issue, but I was wondering if there is a better way.

To replicate the problem:

  • Empty Unity project
  • Import AdMob
  • Create an assembly for the adMob
  • Create a script Like so:
string appId = "myAppID" //Here you put the actual ID, or a test ID
MobileAds.Initialize(appId);
  • Create custom assembly for the script and reference the AdMob assembly to it.

I would appreciate some help. Am I using assemblies wrong?

Hi Nightstriker,

I am having the same issue with the AdMob native library.

Without asmdef file everything works fine but when I add asmdef, MobileAds.Initialize throws null reference exception.

I think it is related to il2cpp code stripping but I could not find a way to prove it.

If you solved this problem please tell us the solution.

Thanks.
