Different Methods to Change Kotlin Version:
There are different methods to change the Kotlin version on Android Studio. Below are three methods that you can use to change the Kotlin version:
Method 1: Using the Project-Level Build.gradle file
This method involves changing the Kotlin version specified in the project-level build.gradle file. Follow these steps to change the Kotlin version using this method:
Step 1: Open your project in Android Studio
Step 2: Click on the "Project" view on the left-hand side of the IDE
Step 3: Expand the "Gradle Scripts" folder and double-click on the "build.gradle(project)" file to open it in the editor.
Step 4: Scroll down to the "dependencies" section of the file.
Step 5: Find the line that specifies the Kotlin version and update it to the version you want to use.
Step 6: Click on the "Sync Now" button to apply the changes.
Pros:
– Easy and straightforward
– Changes can be applied globally without affecting individual modules and projects
Cons:
– May affect the functionality of some libraries or modules in your project if they have a dependency on a specific version of Kotlin
Method 2: Using the Module-Level Build.gradle file
This method involves changing the Kotlin version specified in the module-level build.gradle file. Follow these steps to change the Kotlin version using this method:
Step 1: Open your project in Android Studio
