How do i integrate this application with Google Drive?

Google Drive is not a recommended sync platform for Srivener because of its tendency to corrupt files across platforms (PC/Mac). Even if you are using a PC and are unlikely to have problems within your own system, publishers, designers, and other industry services will likely use Macs. By syncing with Google Drive, you may be risking file corruption when you try to share your Scrivener files across operating systems. The basic version of Dropbox is free and it's very easy to use. I recommend using it, even if only for your Scrivener files.
