title: How to implement Android’s Data Backup Service
body: <p>For my Android Project I tried to follow and implement Android Developers Data Backup Guidelines ( <a href="http://developer.android.com/guide/topics/data/backup.html" rel="nofollow">http://developer.android.com/guide/topics/data/backup.html</a> ), but Data Backup and Restore doesn't work. Can someone help with examples?</p>
