Backups will be handled by launching the application in a special mode under which no activities or services will be started, only the BackupAgent subclass named in the app's android:backupAgent manifest property. This takes the place of the BackupService class used earlier during development. In the cases of *full* backup or restore, an application that does not supply its own BackupAgent will be launched in a restricted manner; in particular, it will be using the default Application class rather than any manifest-declared one. This ensures that the app is not running any code that may try to manipulate its data while the backup system reads/writes its data set.
