-<p>Any application can use the backup manager to save and restore data. To do
-so, the application instantiates a {@link android.app.backup.BackupManager} and
-uses its methods to trigger a new backup or restore operation. The application
-must also create a subclass of {@link android.app.backup.BackupAgent} and
-implement its methods to handle calls from the backup manager to get data for
-backup and provide data to restore
-({@link android.app.backup.BackupAgent#onBackup(android.os.ParcelFileDescriptor, android.app.backup.BackupDataOutput, android.os.ParcelFileDescriptor) onBackup()}
-and {@link android.app.backup.BackupAgent#onRestore(android.app.backup.BackupDataInput, int, android.os.ParcelFileDescriptor) onRestore()}).
-A simple implementation of a BackupAgent useful for backing up preferences 
-and files is available by using {@link android.app.backup.BackupAgentHelper}.
