Error: Requested module not found

[ElSifi]

Hello all

for some reason it's getting this error message

Error: Requested module not found: com.google.android.gms.ads.MobileAds
I'm using Ti SDK 9.3.0.GA

I have suspicions about the Gradle dependancies

so I added

dependencies {
    implementation 'com.google.android.gms:play-services-ads:19.7.0'
}

to resources/platform/android

and still having the same problem

Do you have any suggestions?
