- Sceneform SDK for Android
was open sourced and archived ( github.com/google-ar/sceneform-android-sdk
) with version 1.16.0.
- This site ( developers.google.com/sceneform
) serves as the documentation archive for the previous version, Sceneform SDK for Android
1.15.0.
- Do not use version 1.17.0 of the Sceneform Maven artifacts
.
- The 1.17.1 Maven artifacts can be used. Other than the version, however, the 1.17.1 artifacts are identical to the 1.15.0 artifacts.
