"A problem occurred evaluating project ':app'."

I tried looking at old solutions for this error but some of the suggestions were to change versions. Is that what I should be doing? If so, what version should I change to? And is this related to my other error "Plugin with id 'com.google.gms.google-services:4.3.10' not found."?

CodePudding user response：

In the 'app/build.gradle' file, at the top you have:

apply plugin: 'com.google.gms.google-services:4.3.10'

This should not include the version.

You define the version in the project build.gradle file (the first one you posted)

It should just be:

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