Nice indeed. To add more unsubstantiated rumours, it appear that there are
actually environment variables that store the mount point(s) of secondary
SD cards. Those have been seen in the wild:
EXTERNAL_STORAGE_ALL
EXTERNAL_STORAGE
SECOND_VOLUME_STORAGE
THIRD_VOLUME_STORAGE
System.getenv("EXTERNAL_STORAGE_ALL") returns something like
this on *some* devices:
/mnt/sdcard:/mnt/usbdisk:/mnt/ext_card
So you'd have to check all and/or parse /proc/mounts, and
if you have the magic permission, you might be able to use
the secondary, etc. SD card.
In short, save yourself the trouble and don't bother :)
Using Dropbox, or Google Drive(?), or whatever will
give you less headaches.
