        maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
        google()
        jcenter()
        
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.2'
        //classpath 'com.android.tools.build:gradle:4.0.2'

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


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

    }
}

allprojects {
    repositories {
        google()

        jcenter()
