These were my codes.

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

But when I add this AdMob code, 

implementation 'com.android.support:appcompat-v7:27.1.1'

this code makes error:

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 27.1.1, 26.1.0. Examples include com.android.support:animated-vector-drawable:27.1.1 and com.android.support:customtabs:26.1.0 less... (Ctrl+F1)

  • Use `./gradlew app:dependencies`, then you can find two different versions. – galcyurio Mar 18 '19 at 03:59

This is probably because implementation 'com.google.android.gms:play-services-ads:17.1.1' is implicitly using support libraries 26.1.0. You can override the libraries by adding the exact version of the conflicted libraries. Add something like this:

implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:animated-vector-drawable:27.1.1'
implementation 'com.android.support:appcompat-v7:customtabs:27.1.1'
