If you are running this on the emulator, do you have an SD card image set up? The emulator does not have SD card storage by default -- you need to use mksdcard to create an image and then tell the emulator to use that image via a command-line switch at startup. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Warescription: Three Android Books, Plus Updates, $35/Year --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
