W/Ads: The Google Mobile Ads SDK will not integrate with Firebase.

[Saowaluk Sompong]

W/Ads: The Google Mobile Ads SDK will not integrate with Firebase. Admob/Firebase integration requires the latest Firebase SDK jar, but Firebase SDK is either missing or out of date

What does this Log mean exactly? I have latest version in gradle:

implementation 'com.google.firebase:firebase-core:16.0.0'
implementation "com.google.firebase:firebase-ads:15.0.1"

Hello,

I am not initializing the AdMob sdk (but I was previously told that it was an option step)

And everything is work fine and Ads are displayed.
Just I would like to know where that Log come from. How can Firebase be missing or out of date even.

Hi there,

Since you've mentioned that you have successfully loaded Ads, it is safe to assume that your code implementation specific for Mobile Ads SDK is working correctly. 

For the warning logs captured, I suggest that you have this checked with the Firebase Support Team as they can give more insights regarding this matter.
