I am using 'com.google.android.gms:play-services-ads:12.0.1'. and android support version 27.1.1.
when I try to upgrade my ads library to the latest (15.0.0) I get an error saying that I must use the same version specification. See image below.
Is there a way to use the latest version for both the supportLibraries and the play-services-ads ?
Note that this problem does not exist when i use the play-services-ads version 12.0.1
Change all the libraries to the lowest that has conflict with in your case change some of your libraries from 27.1.1 to 26.1.0.
You can try overriding the conflicted support library by adding the support library to your dependencies block:
I reverted back to 12.0.1
Seems to me that Google need to fix this their end.
Update 4 May 2018:
Firebase-15.0.1 depends on the latest google services
See this blog post
However when I upgraded google services 3.3.0 and firebase-15.0.1 I ran into other issues that I couldn't resolve. Using Google-Services 3.3.0, gradle complained about my library module that I imported:
Gradle Error:
So again my recommendation is not to upgrade.
