How to Pause Video on Navigation in React Native

If you are developing a mobile application using React Native and you’re implementing a feature that involves audio or video playback, you might encounter a common problem: how to pause the playback when the user navigates away from the screen. In this article, we’ll dive into how to effectively manage the video state while using react-navigation and react-native-video to ensure a smooth user experience.

The Problem

Imagine this scenario: You have a video or audio player in one of your screens, and when the user decides to navigate to a different screen, the audio keeps playing even when it's no longer visible. This can create a confusing experience for the user, and consequently, it’s essential to automatically pause the audio or video when the user leaves the screen.

In this case, we’ll explore a solution that uses React hooks and the capabilities of react-navigation. Below is the existing screen code that has the problem:

With the above code, the audio status is set to true (paused) on screen blur, but unfortunately, the audio keeps playing because the player does not respond to this state change.

The Solution

To solve this issue, we will utilize a ref to manage the video's playback state from within our player component. By making some adjustments to both the MainScreen and the Player components, we can ensure the video pauses as expected. Here’s how you can implement the solution:

Step 1: Modify the MainScreen

We need to create a ref for the player and ensure we call the pauseVideo method when the screen blurs.

Step 2: Convert Player to Use Hooks

Next, we will update the Player component to use hooks and expose the pauseVideo method via useImperativeHandle, which allows us to call it from the parent component.

Step 3: Testing Your Implementation

With the above changes, it’s time to test your application:

Play a video on the main screen.

Navigate to another screen to ensure that the video pauses as expected.

Conclusion

By following these steps, you can effectively pause your audio or video playback in a React Native application using react-navigation. This will enhance the user experience by avoiding unexpected audio playback when leaving the screen. Remember, managing state and ensuring components communicate properly is crucial in React Native applications. Happy coding!
