In this session, with the new updates of ARCore, a feature called Custom Track Recording, is a feature where user can do a recording on an AR session, on one device and replay it on another, where also able to save the record as an MP4 file.

No more a moment where devs have to build and run the app on a test device, disconnect the USB cable, and walk around just to test a small code change. Now devs only need to record the AR data track in the test environment with expected phone movement, and test it right from our desk.

Recording and Playback APIs, one user can record a session using one device, and another can play back the same session on a different device. It's possible to share an AR experience with another user easily.
