Hi,
I have a problem with a simple application that captures images from
the camera. It works on the emulator, but throws an exception when I
run it on the HTC Desire.
Here are the relevant log messages:
W/CameraSwitch( 3801): open main camera

I have used the correct <uses-permission> and <uses-feature> tags in

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
Thanks in advance!
