Yeah, I also noticed that. No idea what the lines about a 'camera
switch' are about ...
I also tried the API demos (one of the samples that came with the
Android SDK), and found to my surprise that Google's own camera
preview example also crashed on the HTC Desire. Hope it's not a bug in
the Desire's firmware ... The camera and camcorder apps that came with
the device work perfectly though.
It would be great if other people with a HTC Desire could try the
Camera Preview API demo to verify that they experience the same
problem.
Cheers,
