Understanding the ArCoreApk Availability Issue on API Level 30

Are you facing issues with ARCore availability checks on Android API Level 30? If your ArCoreApk.checkAvailability method is returning false when it worked fine on API Level 29 and below, you’re not alone! This problem has puzzled many developers transitioning their applications to newer Android versions. In this guide, we’ll delve into the problem, discuss its implications, and provide a workable solution to ensure your application continues to function seamlessly.

The Problem: What’s Going Wrong?

When developing applications that utilize augmented reality (AR) with ARCore, it’s vital to check if ARCore is supported and installed on the device. Many developers have encountered a common issue where:

The checkAvailability method returns true for API Level 29 and below.

For API Level 30, however, it unexpectedly returns false.

This inconsistency can lead to user confusion and disrupt the overall functionality of your AR application.

Why Does This Happen?

The changes introduced in Android API Level 30 may affect how your application interacts with ARCore packages. These modifications are detailed in the Android developer documentation, which constantly evolves as new features and capabilities are added to the platform.

A Solution: Update Your Manifest File

To efficiently solve the availability issue, a simple yet effective adjustment can be made in your application’s manifest file. By updating the manifest to include appropriate queries, you can enhance the ARCore detection process. Here’s how you can do it:

Step-by-Step Instructions:

Open your Android Studio project.

Navigate to the manifest file (typically located at app/src/main/AndroidManifest.xml).

Add the following code snippet within the <manifest> tags:

Save the changes and rebuild your project.

What Does This Change Do?

By including the <queries> element in your AndroidManifest.xml file, you explicitly declare your app's intention to check for the ARCore package. This ensures the system correctly handles the availability checks, allowing your application to function appropriately on API Level 30 and above.

Conclusion: Keeping Your AR Application Functional

In summary, the issue regarding ArCoreApk.checkAvailability not working on API Level 30 can be effectively resolved by updating your manifest file. By making this adjustment, your application will have a clear signal about its query for the ARCore package, ensuring smooth functionality for all users.

Don't let compatibility issues slow down your AR development! Always check your manifest and keep up with the latest Android developments to ensure your applications are ready for future updates.

With these insights, you should now feel equipped to tackle ARCore availability issues across different API levels. Happy coding!
