AdMob Unity 5.3 integration problem

I have done everything perfectly as described here https://firebase.google.com/docs/admob/unity/start
I have proper components in SDK manager.
I have imported:
Unity AdMob SDK
Google Play Games SDK for Unity
Had some errors, cleared them all after spending a lot of time.

After all this, I get this damn error:
“File not found: support-v4-.pom”
I cannot solve this error.
And it is annoying me as hell.
Can I please get some help?

This question is also posted at https://askhelpy.com/t/admob-unity-5-3-integration-problem/788 and I request you to please provide the solution there it self.

Hello,

Implementing Admob to unity in this way usually gave me problems, im not saying its not solvable, but my easier solution was Unity Native Plugin from the asset store, it is seemless and makes life easier regarding everything Google related integration in one plugin.

Actualizing Admob to solidarity along these lines more often than not gave me issues, im not saying its not reasonable, but rather my less demanding arrangement was Unity Native Plugin from the advantage store, it is seemless and makes life less demanding with respect to everything Google related reconciliation in one module.
