Authorizing Dropbox
Whenever you first use Dropbox in OnSong, you will need to first authorize OnSong to access your Dropbox contents. This is handled completely by the Dropbox SDK, so no information is passed to OnSong along the way. Dropbox authentication is performed inside of OnSong to avoid confusion if you are signed into another account on an installed Dropbox app on your device.
Getting Dropbox
Dropbox is a popular cloud-based storage service that offers 2 GB of free storage for signing up. You can pay a subscription if you need to store more information. 2 GB is more than enough space for chord charts and OnSong backups. Sign up at http://dropbox.com.
Authorization
Before you can use your Dropbox account with OnSong, you need to sign into Dropbox and authorize OnSong. Enter the email address you use to sign into Dropbox along with your password and tap the Sign In button. This will authenticate you with Dropbox and authorize OnSong to access your Dropbox.
The login and authorization process is handled completely by Dropbox and no credentials are sent to OnSong at any time. OnSong requests access to your entire Dropbox to allow you to import and export files from any folder.
