Hi, cameraX development team.
We have done click animation effect when focusing, so we need to know when focusing ends, but we can't get it in the lifecyclecameracontroller class. I think we should provide a callback monitor for focusing completion to let us know when focusing ends.

Thanks for posting the request. If you are using the tap-to-focus feature of PreviewView/CameraController, right now there isn't a good way to get the callback/ListenableFuture. This is something we will consider in the future.

Hi,

Here's my code for checking focus status, and it works well even with VideoCapture. Hope this helps.
