Does anyone know how to select a camera when there are multiple Back cameras?

I looked at the Multi-camera API page and could not figure out how to do it.

If there are 3 or 4 back cameras, can you give me the code for KOTLIN to select those cameras and show the preview? Thanks in advance.

Hi,

Are you using CameraX or Camera2? Do you want to select a camera based on its ID or other criteria like FOV?

For the devices that support logical camera (as described in https://developer.android.com/training/camera2/multi-camera), CameraX has CameraControl#setZoomRatio that automatically switches between the cameras with different FOV.
