Answer 1

I started seeing this after I upgraded to kotlin plugin version : 1.2.41-release-Studio3.1-1.

Upgrading firebase-core and firebase-messaging from 15.0.0 --> 15.0.2. Fixed the problem, database, auth and gms-auth-services are at 15.0.0

Answer 2

I fix the same issue in my project - after updating the Kotlin plugin to 1.2.41 (I don't know if it is really related. Edit: apparently this is not related with Kotlin) - with :

classpath 'com.google.gms:google-services:3.2.1' 

https://developers.google.com/android/guides/google-services-plugin

Remark: I could stay with the unique 15.0.0 Google Play Services libraries version but not the play-services-tagmanager one and firebase :

implementation "com.google.android.gms:play-services-tagmanager:15.0.2"
implementation "com.google.firebase:firebase-core:15.0.2"

The project is compiling now.

Answer 3

This is very boring. Google should review these updates better. I tried everything, but my issue was only fixed by returning the version of the Google Play Services APIs:

implementation 'com.google.android.gms:play-services-gcm:11.8.0'

Answer 4

For me the problem was

dependencies {
       classpath 'com.google.firebase:firebase-plugins:1.1.5'
}

used for Performance Monitoring. Just commented out.

Answer 5

I fixed the issue using new firebase independent version numbers https://firebase.google.com/support/release-notes/android#latest_sdk_versions

SDK Update - May 2, 2018 -> Firebase Android SDKs now have independent version numbers, allowing for more frequent, flexible updates.

Answer 6

I had the same issue, the thing which is causing this error is 2 versions of same dependency with different services

I changed this:

implementation 'com.google.android.gms:play-services-ads:17.1.0'
implementation 'com.google.android.gms:play-services-analytics:16.0.5'

To:

implementation 'com.google.android.gms:play-services-ads:17.1.1'

these versions are importing same subpackages which is why it is a ambiguity error basically same subpackage is imported from 2 different dependencies (in background)

Have fun coding!!
