How to fix "Failed to resolve com.google.firebase:firebase-ads:9.2.0"?

Question

I have tried to integrate Admob Ads. The very first step is to add these statements to build.gradle.

Project Level

dependencies {
        classpath 'com.google.gms:google-services:3.0.0'
    }

Module level:

dependencies {
            compile 'com.google.firebase:firebase-ads:9.2.0'
        }

apply plugin: 'com.google.gms.google-services'

But when synced getting

 Failed to resolve: com.google.firebase:firebase-ads:9.2.0

How can I integrate these advertisements?

Answer 1

You have to update your Google Play Service to the last version, currently is 31, also your Google Repository must be the last too, now is 29.

Answer 2

I just integrated Firebase analytics as well. I had the same problem though! What seems to fix the problem is changing compile 'com.google.firebase:firebase-core:9.2.0' to compile 'com.google.firebase:firebase-core:9.0.2'. Basically the 9.2.0 should be 9.0.2. I was using this tutorial, and it said to use 9.2.0. I am assuming either the tutorial has a typo or something needs to be updated. This will work though! :)
