Remarks
A helper class that can be used in conjunction with android.app.backup.BackupAgentHelper
to manage the backup of a set of files. Whenever backup is performed, all files changed since the last backup will be saved in their entirety. When backup first occurs, every file in the list provided to #FileBackupHelper
will be backed up.
During restore, if the helper encounters data for a file that was not specified when the FileBackupHelper object was constructed, that data will be ignored. <p class="note"><strong>Note:</strong> This should be used only with small configuration files, not large binary files.
