ARCore SDK for Android v1.33.0

Breaking & behavioral changes

• To use Cloud Anchors, you must now enable the ARCore API instead of the older ARCore Cloud Anchor API, which is now deprecated. To support older app versions, you may enable both while making the transition. Apps built with ARCore SDK 1.32.0 and lower will target the older API, while apps built with ARCore SDK 1.33.0 and higher will target the new API. Note the following:
  • The new API uses the domain name arcore.googleapis.com instead of arcorecloudanchor.googleapis.com.
  • If you are using an API Key which is restricted by API, you must allow the ARCore API.
  • If you send requests to the ARCore Cloud Anchor Management API from your backend, you must also change the domain name to arcore.googleapis.com, after enabling the ARCore API.
  • The old API/endpoint will continue to be supported through August 2023.
  • See ARCore 1.33 Cloud Anchor endpoint changes for more details.
• ArImage has been removed. Use android.media.Image instead.
• targetSdkVersion inside the ARCore aar has been updated to API level 33. Specifying a targetSdkVersion in your project's build.gradle or AndroidManifest.xml will override the ARCore value.
