* {@link android.app.backup.BackupAgentHelper}. That class is particularly
* suited to handling of simple file or {@link android.content.SharedPreferences}
* backup and restore.

* The constructor, as well as {@link #onCreate()} and {@link #onDestroy()} lifecycle callbacks run
* on the main thread (UI thread) of the application that implements the BackupAgent.
* The data-handling callbacks:
* {@link #onBackup(ParcelFileDescriptor, BackupDataOutput, ParcelFileDescriptor) onBackup()},
* {@link #onFullBackup(FullBackupDataOutput)},
* {@link #onRestore(BackupDataInput, int, ParcelFileDescriptor) onRestore()},
* {@link #onRestoreFile(ParcelFileDescriptor, long, File, int, long, long) onRestoreFile()},
* {@link #onRestoreFinished()}, and {@link #onQuotaExceeded(long, long) onQuotaExceeded()}
* run on binder pool threads.
