Cannot resolve GoogleSignIn and GoogleSignInClient

Question

I am not able to use GoogleSignIn(com.google.android.gms.auth.api.signin.GoogleSignIn ) and GoogleSignInClient(com.google.android.gms.auth.api.signin.GoogleSign

Answer 1

For me I was applying a plugin for the google play services in my app's build.gradle:

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

along with that in my Project's Build.gradle I had google services.

buildscript {
    ext.kotlin_version = '1.1.60'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.google.gms:google-services:3.1.2' // <== this guy
        classpath 'com.android.tools.build:gradle:3.0.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

I remember I added them with some compiling issues. But apparently I didn't need them.

By removing them I found there were no more issues with the gms versions.

EDIT

So removing solved my issue initially, but gave me issues later with google sign in. adding the apply plugin: 'com.google.gms.google-services' to the bottom of my projects gradle instead of at the top did actually solve it.
