Thanks, I didn't know of the android-platform group, I've posted my question there.
Meanwhile, do you have any idea why I would encounter the above-mentioned problems with SharedPreferences? I've also tried simply creating a file in /mnt/sdcard in the framework with the intention of the app reading it later, but I was thrown a permission denied error. I was under the impression that accessing the external sdcard required no special permissions, but if permissions are necessary, I'm not even sure where to specify it since I can't seem to find the AndroidManifest.xml of this particular framework component. Thanks again. On Monday, August 13, 2012 10:31:47 PM UTC+8, Kristopher Micinski wrote: > > This group is solely for SDK related applications.
