The application's restore operation has completed. This method is called after all available data has been delivered to the application for restore (via either the BackupAgent.OnRestore(BackupDataInput, System.Int32, System.Int32) or BackupAgent.OnRestoreFile(Android.OS.ParcelFileDescriptor, System.Int64, System.Int64, System.Int64, System.Int64, System.Int64) callbacks). This provides the app with a stable end-of-restore opportunity to perform any appropriate post-processing on the data that was just delivered.
