Description

Is there a way to keep a Room camera/microphone active when the app is placed into the background, and if so, detect if camera/microphone are being utilized by another app or have a callback notifying the app that the camera/microphone are no longer available?

Steps to Reproduce

Utilize a foreground service that will allow the camera/microphone to be used while the app is in the background (not needed in this example but better practice)
Do not release the camera onPause (goal is to only hold the camera/microphone if Room is active)
Open another camera app such as the native device Camera app

Code

N/A

Expected Behavior
