If you're an Android developer, you know that working with collections in Java can be a bit of a hassle.

Step 1: Add the Dependency to Your build.gradle File

First things first, let's add the dependency to our build.gradle file. Open your app-level build.gradle file and add the following line to the dependencies block:

implementation 'org.apache.commons:commons-collections4:4.4'

This will add the latest version of Apache Commons Collections to your project.

Step 2: Sync Your Project

After adding the dependency, sync your project with Gradle by clicking on the "Sync Now" button in the toolbar or by running the "Sync Project with Gradle Files" option from the "File" menu.

Step 3: Start Using Apache Commons Collections

With the dependency added and your project synced, you can start using Apache Commons Collections in your code. Here's an example of how to use the ListUtils class to reverse a list:

import org.apache.commons.collections4.ListUtils;

List<String> names = new ArrayList<>();
names.add("John");
names.add("Jane");
names.add("Bob");

List<String> reversedNames = ListUtils.reverse(names);

In this example, we import the ListUtils class and use it to reverse the order of the names list.

Conclusion

Adding Apache Commons Collections to your Android Studio project is a breeze thanks to Gradle. With this powerful library at your fingertips, you can simplify your code and focus on building great apps.
