How to backup/restore SQLite database on Android to Dropbox

Using the answer here, you can get a reference to your database in the form of a .db File object.

final String inFileName = "/data/data/<your.app.package>/databases/foo.db";File dbFile = new File(inFileName);

Once you have this, it's easy to read/write to a user's Dropbox using the Dropbox Sync API.

Backup: Use writeFromExistingFile() to write this local File to the Dropbox directory
Restore: Use getReadStream() to get a FileInputStream that can write to the appropriate local path where your .db file goes.
