In many mobile applications, providing the ability to open PDF files directly in the device’s default viewer instead of the browser enhances the user experience significantly. In this guide, we will explore how to achieve this in a React Native environment.

Using React Native Linking

The React Native Linking library is a powerful tool that enables opening external URLs, including files, with the default applications installed on a device. Here’s a step-by-step guide to using React Native Linking to open PDF files in the default viewer.

Step 1: Install and Import Necessary Libraries

First, make sure you have the React Native Linking API available in your project. It usually comes pre-installed with React Native, but you can add it explicitly if needed.

In this example, when the button is pressed, it will open the specified PDF file using the default viewer on the device, providing a more consistent and user-friendly experience compared to opening the file in the browser.

Conclusion

By leveraging the React Native Linking library, you can easily open PDF files in the default viewer on a user's device, improving the overall usability and experience of your mobile application. Incorporate the steps above to achieve this functionality in your React Native projects.
