Stay organized with collections Save and categorize content based on your preferences.

In November 2022, Google Play Services for AR will remove deprecated methods related to NDK camera images and metadata.

Apps using these methods in affected versions of the ARCore SDK might start to behave differently or crash when users update Google Play Services for AR.

Affected apps

Beginning in November 2022, your app may stop working or crash when users update to the latest version of Google Play Services for AR if:

  1. Your app was compiled with an affected SDK
  2. Your app uses any of the following affected APIs:
If your app was compiled with
ARCore SDK version…
And uses affected APIs… Breaking behavior starting in November 2022
1.19.0 or lower Frame.getImageMetadata() Throws IllegalArgumentException.
1.10.0 or lower Frame.acquireCameraImage() Returns a 0x0 sized image.

Fix affected apps

Affected apps may see breakage in November 2022. To mitigate this, rebuild your app using the latest ARCore SDK. At a minimum, you must upgrade to ARCore SDK version 1.20.0 or later.

Verify affected app is fixed

Test the app by simulating the November 2022 changes in advance by adding a special meta-data entry to your app's AndroidManifest.xml:

  1. Ensure Play Services for AR version 1.29.0 or higher is installed on the target device.
  2. Add a new <meta-data> tag as a child of the existing <application> element in the app's AndroidManifest.xml file :

    <application …>
      …
    
      <!--
           Simulate the November 2022 changes in advance.
           IMPORTANT: Remove this tag when testing is completed.
           Do not include this tag in published versions of your app.
      -->
      <meta-data android:name="com.google.ar.core.session_settings"
                 android:value="camera_stack_option,unified_mono" />
    </application>
    
  3. Test your app and verify that all ARCore features are functioning as expected.

  4. Remove the <meta-data> tag when testing is complete. Leaving this tag in place in your published app could result in unexpected behavior in the future.

If the app functions normally, then the app is ready for the changes in November 2022.
