[ODK Community] Move ODK Collect data to SD card?

yanokwa · March 19, 2013, 11:40pm

Mary,

By default, ODK Collect writes all form data to the SD card. If you
want to transfer the form data to your local computer, make sure to
try ODK Briefcase at http://opendatakit.org/use/briefcase/

Hi,
I'm using a Samsung Galaxy Y Duos Android phone to access ODK Collect.

I tried doing this from the app manager settings, and when that didn't work I downloaded "App2SD" from the Google Play Store, but it says the ODK collect app is "Phone only". Is there a way to move this app and saved surveys to an SD card? Ultimately I want to be able to backup saved surveys on the SD card and transfer them to my computer, and I'm a little unsure if this is even something that can be done.....can anyone help me out on either count?

Mary,

I bet this is one of the Samsung Devices that doesn't do the right
thing when we call Environment.getExternalStorageDirectory().

This is a known issue (see
https://code.google.com/p/opendatakit/issues/detail?id=447) but it
isn't high priority for the core team.

Star the issue to help make it higher priority, and if this is urgent
problem, you can hire a developer to fix it at

Yaw,
Is it possible that at the moment the ODK collect is installed, it checks
to see if there is an SD Card inserted into the phone, and if not decides
that it will have to use the "internal" SD storage area there on and
forever?

Hi Curtis,

This is a problem bigger than just ODK. Other applications that use SD
storage, especially those that store a lot of data, are facing the
problem. We've faced it in our own applications here at the Serval
Project and MaGDAA Project and are currently evaluating what we can
do.

The issue comes down to two main components.

As was noted in an earlier message thread[1] Android changed the
way that SD Cards are used. The change basically boils down to the
fact that the officially supported Java methods that in the past would
return the path to the external strorage, that is storage that is made
available via an SD Card in a slot on the device, now always return
the path to the storage that is internal to the device.
Different device manufacturers, and different Android ROMs, make
the storage available on an SD Card inserted into the slot on the
device via an arbitrary path. Some devices / ROMs use
/mnt/sdcard/external_sd others use /mnt/externalSD others use a
different path.

Basically this means that there is no clean and reliable way to
determine the path to the storage on a SD Card inserted into slot of
the device.

Therefore in newer versions of Android, I believe from version 3.0 and
later, there is no clean and reliable way for an application to
determine if it can store data on an SD Card inserted into the slot of
a device. Additionally devices hat have an SD Card are becoming
increasingly rare as device manufacturers appear to prefer having
storage on the device only.

ODK Collect, and other applications, when using the officially
supported API will always find that the path to the "internal" storage
(that is storage that is physically part of the device) is returned
when requesting the path to store data on the SD Card, wether an SD
Card is inserted into the slot on the device or not. It doesn't matter
when the lifecycle of the app the request for the path for storage is
made, the result is always the same. The "internal" storage (part of
the device) is made available in preference to the "external" storage
(an SD Card).

It isn't the fault of ODK Collect or any other application, the fault
in my opinion, lies with this change in policy of Android and the
device manufacturers being inconsistent.

Hope this helps.

-Corey
