    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.2.0'
        classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.31'
    }
  }
  
  

3. Sync your project with Gradle files by clicking on the “Sync” button in the top-right corner of Android Studio
