After finally figuring out how to do this (Windows doesn't make it easy), I found it didn't make any difference. I went through the "Safely remove hardware" steps, and that removed the drive from File Explorer. Then, I reran the app, and it still complained about the SD card when I pressed the camera button. At that point I disconnected the USB cable and pressed the camera button again, and this time it worked. > On Dec 19, 5:24 am, Mark Murphy <[email protected]> wrote: > > > On Sun, Dec 19, 2010 at 1:29 AM, David Karr <[email protected]> > > wrote: > > > Sorry, I need more information. > > > ? > > > > You're saying that because I had the phone connected to my computer > > > with the USB cable (so I could deploy the application to the device), > > > that means that the SD card in the phone is mounted on the WinXP box, > > > and so can't be used from the phone? > > > No, I mean that if you mounted the SD card as a drive while connected > > to USB, the SD card is unavailable to Android. > > > > Is there something that should > > > be done in the setup of the test on the phone so that I would unmount > > > the SD card from the WinXP box, but still let me step through the code > > > while it's running on the phone? > > > Don't mount the drive in the first place.
