Introduction
facing an issue with your Android project while trying to add the Taboola SDK? Specifically, are you encountering an error stating “unable to find valid certification path to requested target”? Don’t worry, we’ve got you covered! In this article, we’ll explore the possible causes of this error and provide step-by-step solutions to help you resolve it. So, let’s dive in and get your Taboola integration up and running smoothly!
Understanding the Error
When working with the Taboola SDK in an Android project, you might come across the “unable to find valid certification path to requested target” error. This error occurs when your project is unable to establish a secure connection with the Taboola repository due to certificate-related issues. However, it can be perplexing because you can access the URL without any problems in the browser on the same machine. Let’s explore the possible causes and solutions for this error.
1. Check Your Network Connection
Before delving into complex troubleshooting steps, ensure that your machine has a stable internet connection. Sometimes, network issues can interfere with the secure connection establishment process, leading to the certification path error. Try accessing other websites or repositories to confirm that your network connection is functioning properly.
2. Verify URL and Repository Configuration
Double-check your project’s build.gradle file and confirm that you’ve added the Taboola repository URL correctly. Ensure that the URL is accurate and doesn’t contain any typos or formatting errors. Even a small mistake in the URL can prevent the successful retrieval of the required resources.
3. Gradle Configuration: Allowing Other TLS Protocols
The “unable to find valid certification path to requested target” error can occur if the server doesn’t support the TLS protocol versions used by your Gradle configuration. To resolve this, you can configure Gradle to allow other protocols to be used. Follow these steps:
- Open your Gradle build configuration file.
- Add the following line to the file:
System.setProperty("https.protocols", "TLSv1,TLSv1.1,TLSv1.2,TLSv1.3") - Sync your project to apply the changes.
By allowing multiple TLS protocol versions, you ensure that Gradle can negotiate a compatible protocol with the server, resolving any protocol compatibility issues.
4. SSL Certificate Installation
In some cases, the error can be related to the SSL certificate chain. While you’re able to access the URL in the browser, your Android project might require additional intermediate certificates to establish a valid certification path. Here’s what you can do:
- Visit the Taboola repository URL in a browser on your machine.
- Inspect the SSL certificate details and identify any intermediate certificates used.
- Download the intermediate certificates from the certificate authority’s website.
- Install the downloaded certificates in your Android project’s certificate store.
- Sync your project to apply the changes.
By providing the necessary intermediate certificates, you ensure that your project can establish a valid certification path to the Taboola repository.
Conclusion
Encountering the “unable to find valid certification path to requested target” error while accessing the Taboola SDK can be frustrating. However, by following the troubleshooting steps outlined in this article, you can resolve the issue and continue integrating Taboola into your Android project without any obstacles. Remember to double-check your network connection, verify the URL and repository configuration, adjust the Gradle configuration to allow other TLS protocols, and install any required SSL intermediate certificates. With these solutions, you’ll be well-equipped to overcome the certification path error and make the most of the Taboola SDK in your Android application.
