List Device Camera ID

Hi everyone, hoping for some help here.

Working on a app for employees doing site visits and inspections. Basically they create an entry on a SharePoint list for the visit, record information and upload photos.

Everything is working fine but I do have one issue. I use a camera control to take photos within the app and use a Flow to attach them to the appropriate entry on the list (Side note, is there a way to do this without a flow? I couldn't figure it out)

The issue I have is with the camera ID. On app start, I set a variable called cameraIndex to 0 and use that to set which camera the app is using. I have two icons on the screen, one which increases cameraIndex by 1 and one which decreases it by 1 (to a minimum of zero.) This works fine except I have no way to know what the max camera ID of the end user's device. They can cycle through until they get an error message and then go back a step.

Is there a way I can know which camera IDs are available? It bugs me because the app is pretty polished except for this one feature I can't figure out.

You could possibly use IfError(...your code here..., -1) in your math for your button that way if it produces an error it will catch said error and auto decrease the value by 1 for you. Should surpress the error as well. Worth a shot.

No idea how I missed this but there is a property called AvailableDevices which, obviously, does exactly what I need. For future reference, this is how I have it set up.

In OnStart, I have the following
Set( cameraIndex, Min( Camera1.AvailableDevices, Id ) )

I have two buttons on the camera screen with OnSelect the following
Set( //Decreases cameraIndex variable by 1 to minimum available value cameraIndex, Max( Min( Camera1.AvailableDevices, Id ), cameraIndex -1 ) ) Set( //Increases cameraIndex variable by 1 to max available value cameraIndex, Min( Max( Camera1.AvailableDevices, Id ), cameraIndex +1 ) )

And Camera1.Camera is set to cameraIndex
