A convenient Android.App.Backup.BackupAgent wrapper class that automatically manages heterogeneous data sets within the backup data, each identified by a unique key prefix. When processing a backup or restore operation, the BackupAgentHelper dispatches to one or more installed Android.App.Backup.IBackupHelper objects, each of which is responsible for a defined subset of the data being processed.

An application will typically extend this class in its own backup agent. Then, within the agent's BackupAgent.OnCreate method, it will call BackupAgentHelper.AddHelper(string, Android.App.Backup.IBackupHelper) one or more times to install the handlers for each kind of data it wishes to manage within its backups.

The Android framework currently provides two predefined Android.App.Backup.IBackupHelper classes:

• Android.App.Backup.FileBackupHelper - Manages the backup and restore of entire files within an application's data directory hierarchy.
• Android.App.Backup.SharedPreferencesBackupHelper - Manages the backup and restore of an application's Android.Content.ISharedPreferences data.

An application can also implement its own helper classes to work within the Android.App.Backup.BackupAgentHelper framework. See the Android.App.Backup.IBackupHelper interface documentation for details.
