Hi,

Think i've fixed it, what its highlighting issue its a 'plugin' which is not the same version, and your updated version of gradle, they are two different things

https://stackoverflow.com/questions/25994163/could-not-resolve-all-dependencies-for-configuration-classpath

I've changed this section to - 

dependencies {

classpath 'com.android.tools.build:gradle:4.2.0'

classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

classpath 'com.google.gms:google-services:4.3.3'

}

and error has gone, but now got another error showing instead, hope this works
