How to update gradle in android studio?

Updating Gradle in Android Studio is an important step to keep your project up to date and leverage the latest features. Here are the steps to update Gradle:

1. Open the Project: First, open your Android Studio and load the project you want to update Gradle for.

2. Modify Gradle Version:

   • Locate the gradle/wrapper/gradle-wrapper.properties file in the root directory of your project.
   • Open the file and find a line similar to: distributionUrl=https://services.gradle.org/distributions/gradle-x.y-all.zip.
   • Replace x.y with the new version number you want to use. Ensure you select a version compatible with your Android Studio. You can view all available versions on the Gradle official website.

3. Update Gradle Plugin:

   • Open the build.gradle file of your project (project-level, not module-level).
   • Within the dependencies block, find the Gradle plugin and update it to the latest version, for example:

     gradle
     classpath 'com.android.tools.build:gradle:x.y.z'

   • Replace x.y.z with the new version number. You can find the latest version number on the Google Maven repository.

4. Sync the Project:

   • After completing the above steps, click the Sync Project with Gradle Files button in the Android Studio toolbar. This will make Android Studio resynchronize and rebuild your project based on the new configuration.

5. Check and Debug:

   • After the update, verify that your project still runs normally. Sometimes, updating Gradle or the plugin may introduce incompatible changes, which can cause build failures or runtime errors in the application.
   • If you encounter issues, check the Logcat or Console output in Android Studio to find possible error messages and make the necessary adjustments.

Example

Suppose the original Gradle version is 6.5, and we want to update to 6.7. We will modify the gradle-wrapper.properties file as follows:

properties
distributionUrl=https://services.gradle.org/distributions/gradle-6.7-all.zip

Similarly, if the original Android Gradle plugin version is 4.1.0 and we want to update to 4.2.0, we will modify the project-level build.gradle file as follows:

gradle
classpath 'com.android.tools.build:gradle:4.2.0'

After completing these steps and syncing, your project should build using the new Gradle version and plugin version.
