Android Question FirebaseAdMob Issue (LoadAdWithTestDevice) [SOLVED]

Hi!

After fixing many things today regarding SDKManager, missing libs, DEX issues and so on ....
now I am faced with the follwing, new issue:

I can compile my app without any problems - so far so good,
but while runtime while trying to show my activiy with my normal AdBanner ...


... I get every time this exception:

java.lang.NoSuchMethodError: No virtual method addTestDevice(Ljava/lang/StringLcom/google/android/gms/ads/AdRequest$Builder; in class Lcom/google/android/gms/ads/AdRequest$Builder; or its super classes (declaration of 'com.google.android.gms.ads.AdRequest$Builder' appears in /data/app/de.padlockblue.manager-rlxyQEL7PreeBAQXnaDgBg==/base.apk)

So, I guess there was a replacement of a lib or something like this.
Any idea, what to do in such a case?

I am using this in order to see real AD BANNERS - provided from google - but not to pay with it - because the TESTDEVICE ID is given and inserted in this method as a parameter from B4A log.

Using admob 2:



Using method: LoadWithTestDevice (with my own device ID):
