Need some existing code fixed - must know Android and Dropbox SDK use.

I have an existing application that has some broken code in it. Basically it can upload the applications database to Dropbox without issue for backup. However, it cannot download/restore the database. The existing block of "download" code is not very big and probably does not need much work. It may be as simple as fixing a couple of lines of code to as complex as writing a single activity or intent. I'm classifying this as "homework help" because for someone who knows the Dropbox SDK, this will be something they can probably fix in a few minutes to an hour at most.
