Introduction

As Android developers, we frequently strive to optimize how we load and display large datasets in our applications. The Paging library is a powerful tool for doing just that. However, what happens when you want to use different versions of the Paging library—like Paging 2 and Paging 3—in the same project? This can present challenges, particularly in managing dependencies across various modules of your application.

In this guide, we’re going to explore how to effectively use both Paging 2 and Paging 3 in your Android application, enabling smooth navigation and displaying paginated data without any dependency conflicts.

Understanding the Problem

The primary challenge arises when trying to implement Paging 3 in one module and Paging 2 in another. When you pull in Paging 3 dependencies into both modules, conflicts can occur, pulling in unwanted versions of components from one library into another.

This guide will help you understand how to separate these dependencies so that both versions can coexist peacefully in your project.

The Solution

Here’s how you can work with both versions of the Paging library in your Android module:

Step 1: Identify Your Modules

Make sure you have at least two modules in your project:

One using Paging 2

The other using Paging 3

Step 2: Exclude Paging 3 in Your Paging 2 Module

In the module where you want to use Paging 2, you will need to explicitly exclude the Paging 3 dependencies. You can do so by adding the following code snippet to your build.gradle file of the Paging 2 module:

Explanation:

Exclude Statement: By using the exclude function, you can specify which modules within the androidx.paging group to ignore. This prevents Paging 3 components from leaking into the Paging 2 module.

Replace with Version: Always remember to replace x.y.z and 2.x.y with the actual versions you are using.

Step 3: Configure Your Paging 3 Module

In the same way, ensure your Paging 3 module correctly pulls in only Paging 3 dependencies. Here’s a snippet for the Paging 3 module:

Key Points:

This code should pull in the Paging 3 library without including any older versions or causing conflicts.

Conclusion

By following these steps, you can reap the benefits of both Paging 2 and Paging 3 in your Android project, allowing you to manage complex datasets efficiently across multiple modules. The process mainly revolves around controlling your dependencies through exclusions, ensuring that each module only retains the specific library version it requires.

In summary, keep your dependencies organized, use exclusion rules wisely, and you'll be on your way to a streamlined development process.

Happy coding!
