Gradle is the build tool used by Android Studio Arctic Fox. Here’s how you can configure your Gradle settings:

1. Open Your Gradle File:

   • Navigate to File > Open... and select your project’s build.gradle file.

2. Configure Dependencies:

   • Add dependencies required by your project. For example:
     groovy
     implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
     implementation 'androidx.core:core-ktx:1.6.0'
     implementation 'androidx.appcompat:appcompat:1.3.1'
     implementation "androidx.fragment:fragment-ktx:1.3.6"
     implementation 'com.google.android.material:material:1.4.0'

3. Configure Build Features:

     groovy
     buildFeatures {
     dataBinding true // or viewBinding true
     }

4. Configure Kotlin Options:

   • Set the JVM target for your Kotlin code:
     groovy
     kotlinOptions {
     jvmTarget = '1.8'
     }

5. Configure Build Types:

   • Define build types (e.g., debug, release):
     groovy
     buildTypes {
     release {
     minifyEnabled false
     proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
     }
     }

Handling Kotlin Configuration Issues

Sometimes, even with proper configuration, issues related to Kotlin configuration might arise. Here’s how you can troubleshoot and resolve common issues:

"Kotlin Not Configured" Error

If a "Kotlin not configured" error occurs after upgrading to Android Studio Arctic Fox, it might be due to missing dependencies or incorrect configuration. Here’s how you can resolve it:

1. Check Dependencies:

   • Ensure that the necessary Kotlin dependencies are added in your build.gradle file. For example:
     groovy
     implementation "org.jetbrains.kotlin:kotlin-android-extensions-runtime:$kotlin_version"

2. Verify Gradle File:

   • Review your top-level build.gradle file to ensure that the Kotlin version is correctly set:
     groovy
     ext {
     kotlin_version = "1.5.21"
     version_navigation = "2.3.5"
     version_lifecycle_extensions = "2.2.0"
     version_lifecycle = "2.3.1"
     version_room = "2.4.0-alpha04"
     version_coroutine = "1.5.0"
     }

3. Clean and Rebuild Project:

   • Sometimes, cleaning and rebuilding the project can resolve configuration issues:
