Make sure to add to your root-level build.gradle
buildscript {
// ...
dependencies {
// ...
classpath 'com.google.gms:google-services:4.3.2'
}
}
Then, in your module level Gradle file (usually the app/build.gradle), add the 'apply plugin' line at the bottom of the file to enable the Gradle plugin:
apply plugin: 'com.android.application'
android {
// ...
}
dependencies {
// ...
implementation 'com.google.firebase:firebase-core:9.6.1'
// Getting a "Could not find" error? Make sure you have
// the latest Google Repository in the Android SDK manager
}
// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'
As said in documentation. I had exception as in a question above when forgot to add this in my gradle files.
