How to download file from Google Drive and restore db from it

Using the quickstart provided by Google I managed to upload a copy of my SQLite DB to my Google Drive properly. My only problem now is getting it back and restoring using that file.

I read here that since I've already uploaded the file I should have access to it as well. So far I can follow that, but when it goes down to reading the contents I get confused.

I'm still new so I can barely understand the processes I see on the demos, so far from what I can tell all I can do right now is ( I hope I'm actually doing it, I just follow the demos ) locate it. So now I'm stuck at HOW do I get it back? Can anyone lend a hand?

My original plan was to just download the file into a specified folder on my SD and just restore from that since I already know how to do backups and restoration from SD.
