- I've also tested on a second phones, so it's not a phone specific thing.
- I formated using the phone, windows and linux with no discernable difference.
- I copied the files using windows and linux directly to the SD card and via the USB cable with no difference in behaviour.
- The file permissions, owner and owner ID are all the same on the directories read by the app and those not able to be read by the app.
- I've seen my test program be able to read some directories but after making a small modification to the app the directory becomes unreadable.
- The QDir iterator code I posted and this opendir/readdir code product the problem:
bool listdir(const char *name, int level)
{
DIR *dir;
struct dirent *entry;
struct stat st_buf;
dir = opendir(name);
if (dir == NULL) {
fprintf(stderr, "opendir error %d [%s] for %s\n", errno, strerror(errno), name);
return false;
}
entry = readdir(dir);
do {
if (entry == NULL) {
if (errno)
fprintf(stderr, "readdir error %d\n", errno);
}
char filepath[512];
memset(filepath, 0x00, 512);
if (entry == NULL) {
fprintf(stderr, "readdir error %d", errno);
return false;
}
strcpy(filepath, name);
strcat(filepath, "/");
strcat(filepath, entry->d_name);
if (stat(filepath, &st_buf) == -1) {
fprintf(stderr, "stat error %d on %s", errno, entry->d_name);
return false;
}
if (S_ISDIR(st_buf.st_mode)) {
char path[1024];
int len = snprintf(path, sizeof(path)-1, "%s/%s", name, entry->d_name);
path[len] = 0;
if (strcmp(entry->d_name, ".") == 0 || strcmp(entry->d_name, "..") == 0)
continue;
printf("%*s[%s] (%d)\n", level*2, "", entry->d_name);
listdir(path, level + 1);
}
else
printf("%*s- %s (%d)\n", level*2, "", entry->d_name);
errno = 0;
} while ((entry = readdir(dir)));
closedir(dir);
fflush(stderr);
fflush(stdout);
return(true);
}Whatever mechanism that enforces the acess_shared permission, over and beyond the filesystem based permissions, seems to be inconsistently applied to the SD card filesystem. Incidently, while testing I removed access_shared permission for my app but still managed to access shared folder and files... (via settings->security->app permissions),
