On CommCare ODK there are several additional question types that cannot be used on the J2ME version. There are also some unique configuration or design issues to keep in mind while building your app.
Image Question (captures an image)
CCODK cannot accept large image files. Anything greater than 1MB could cause issues including slow syncing and failure to upload the picture to CCHQ.
The best rule of thumb is to use a small (< 1MB) file size when taking pictures within CC. VGA files seem to work particularly well. You may have to manually adjust this in your camera app if you prefer to take larger size pictures outside of CommCare.
If you are looking at a report in CCHQ and you either can't find an image you know you captured, or you see an image file name but it is not linked to anything, make sure that you did not take a very large image.

Case List Details
In CCODK case list view it is important not to put too much text or data in the "short view" as this will make it very difficult to navigate through the case list. Click here for more information on case lists.
