SumerianARCoreStarter can't build project. Have only updated the scene URL and attempted to build in Android Studio on Windows (fresh install of AS). and this error occurs.

I think this could be a general problem with your system setup. Searching for the issue on StackOverflow reveals many similar issues.

One solution could be to click on "Please configure Android SDK" in the Logcat window (source: https://stackoverflow.com/questions/56373903/generate-signed-apk-classnotfoundexception-com-google-wireless-android-sdk-s )

It could also be related to some versions of Android Studio. Try to update to the latest version: https://stackoverflow.com/questions/56053161/errorinternal-error-java-lang-classnotfoundexception-com-google-wireless-and

Closing this out as a local setup issue.
