How to Catch PlayerError in NativeScript ExoPlayer and Show a Proper Alert

When developing applications with NativeScript and using the ExoPlayer plugin, you might encounter problems when users face connection issues. A common challenge developers face is how to notify users when a video cannot be loaded due to connectivity problems. If you see an error message like this in your console:

this indicates that the ExoPlayer is unable to stream the video content as expected. In this guide, we provide a step-by-step guide on how to catch these PlayerErrors and present a proper alert to your users to enhance their experience.

Understanding the Issue

When there is a connectivity issue, the video player throws an error, which, if not handled, can lead to confusion or a poor user experience. As a developer, it is crucial to intercept these errors and notify the user appropriately.

The Solution: Catching PlayerError

To catch the PlayerError in NativeScript ExoPlayer and show a user-friendly alert, follow these organized steps:

Step 1: Locate the Error Handling Code

First, you need to tap into the error handling capabilities of the ExoPlayer plugin. Open the videoplayer.android.js file located in your node_modules. Look for the onPlayerError function:

Step 3: Integrate with the PlayerError Handling

Now that you have your error handling function defined, you need to call it within the onPlayerError method. Doing so will ensure that whenever an error is caught, your custom alert will be triggered:

Step 4: Test Your Application

After integrating the above changes, it’s essential to thoroughly test your application. Simulate poor network conditions and observe whether your alert displays as intended when the video fails to load. This real-world testing will help ensure that users are effectively notified of any issues.

Summary

Handling PlayerErrors in your NativeScript ExoPlayer application is not just about fixing bugs but also about providing a great user experience. By following the steps outlined in this guide, you can catch connection issues and show clear alerts to your users.

Identify the error handling code in the ExoPlayer plugin.

Define a method in your component to manage user notifications.

Hook into the onPlayerError function to trigger alerts as needed.

Now your users will have a smoother experience knowing there’s an issue—enhancing overall satisfaction with your application!
