On build 3610
I just tested it on Android 10, and it doesn’t capture the image. The response I get is similar to yours. The ‘event.completed’ returns false. I even tried saving it to a file. It works on Android 6 though.
I remember my app that uses media.capture works on the older builds, like 35xx
Maybe you can report an issue in github.
media.capturePhoto( { listener = sessionComplete, destination = { baseDir= system.TemporaryDirectory, filename='123.jpg' } } )
