Alex,
Unfortunately, you have found something that we do not have an answer for
yet. Briefcase is designed to interface with mounted drives which means the
MTP protocol does not quit fit what briefcase was designed to access
mounted drives.
I have created an issue to fix it but we are in the middle of trying to get
other releases out so it will be a few weeks before anyone on the ODK core
team looks at it.
http://code.google.com/p/opendatakit/issues/detail?id=682
Star the issue if you want to follow the progress.
Patches to solve the problem are welcome!
Additionally, suggestions or code from anyone who has written a java
program to move files over MTP is welcome!
Regards,
Waylon

We are planning to use Asus Nexus 7 tablets for our data collection in
Liberia in the coming few months. These devices are great as they: 1)are
relatively cheap and well-built, 2) have a great, easy to read screen even
in some sunlight, which is made especially useful by the newly implemented
feature of having several survey questions on the same screen in ODK
Collect 1.2, and 3) have a long battery life (>10h) and are reasonably fast.
So far, they have performed admirably well with the ODK ecosystem (running
both ODK Collect and Kobo Collect with no issues or crashes, syncing to ODK
Aggregate with no issue, etc.) despite running a brand-new version of
Android. Or so it was, until today...
I began testing ODK Briefcase, and realized that, because all Android 3.x
and 4.x (Honeycomb and Ice Cream Sandwich/Jelly bean) devices have switch
away from mass-storage class (MSC) transfer protocol to Media Transfer
Protocol (MTP) connection when plugged into a host computer using USB, ODK
Briefcase will not recognize the memory card when selecting "Pull" and then
"Mounted SD Card".
The device shows up as a media player though the memory card content is
still present and accessible via normal Windows navigation, and does not
have a drive letter (as do all MTP devices, unfortunately). I have so far
been unable to find a walk-around (tried the usual: enabling/disabling USB
debugging mode, installing the Asus ADB drivers, etc.) to no avail.
My understanding is that MTP is read-only from the host computer's point
of view. Since no writing on the memory card has to be done for ODK
Briefcase to work, it should be possible to get it working. Does anybody
have a suggestion? I'm guessing that ODK will have to be modified sooner or
later to accommodate MTP since it has become the standard for recent
Android devices.
Thank you very much for any help and I look forward to hearing from you

One solution until a java to MTP solution is found (suggestions welcome) is
to use the OS that has recognized the MTP and copy the ODK directory files
into a local directory on the OS. The use the 'Custom Path to ODK
Directory' option to specify the path to the local copy of the ODK
directory.
I realize less is a sub-optimal solution but hopefully someone will have
suggestions or sample code of a java program reading files over MTP so it
will reduce the time until the problem is completely solved.
Patches and/or suggestions on how to solve the problem are welcome!

Is there an off chance that in your wireless settings there is a line USB
utility? My Samsung Note has that and I have to run that to get MSC,
otherwise the default is MTP upon connection w USB cable.

Thanks for getting back to me Waylon! I stared the bug you opened and will
keep an eye on it. I hope this is something that can be resolved at some
point so that users have a greater set of options for android devices to
use (though as you mention in your next post, this is not a deal-beaker by
any means). I know you guys are busy and I appreciate any help.
I'll continue looking at options and will post what I can find/test on this
thread for future reference. I think in the end, the easier approach for us
will be to pull the completed forms 4 devices at the time using a USB hub
and a script either in ADB or something else (I saw one that was written
using Python somewhere on this board). Once the data is all at one place,
we can still use ODK Briefcase to aggregate, encrypt and send it over to
our ODK Aggregate server.

I have a galaxy nexus running google jelly bean, i think the menus are
similar to the asus nexus. When you connect your device. In the line of
curtis have told to you. You could try to run the device as a ptp.
Im only guessing i have no tecnical knowledge about it.
You tap on the notification "connected as a media device" an then you tap
on "camera (PTP)"
I think thats the only other option you will have. But i repeat i have no
tecnical knowledge about the connectivity but i will give it a try.
I have atached screenshots.
i wish you luck

Thank you for the suggestion and screenshots, Guillermo! The screens
look just like those on the Nexus 7, but unfortunately, I had tried
that before posting. PTP makes the device show up as a camera in
Windows, and limits the folders accessible to only DCIM and Pictures,
so in a way this is even more problematic than the regular MTP option.
To be sure, I also tested PTP in combination with USB debugging and
without (as I had also done with the regular MTP approach) but that
made no difference (before and after installing the Asus ADB drivers
for the Nexus 7).
