| Scott Main | b83a283 | 2010-04-29 13:26:53 -0700 | [diff] [blame] | 12 | <p>All backup and restore operations are controlled by the {@link |

| kopriva | 7ecfe31 | 2018-09-17 15:17:50 -0700 | [diff] [blame] | 14 | like to enable backup and preserve its data on remote storage must implement a |
| Scott Main | b83a283 | 2010-04-29 13:26:53 -0700 | [diff] [blame] | 15 | backup agent. A backup agent can be built by extending either {@link android.app.backup.BackupAgent} |
| 16 | or {@link android.app.backup.BackupAgentHelper}. The {@link |
| 17 | android.app.backup.BackupAgentHelper} class provides a wrapper around {@link |
| 18 | android.app.backup.BackupAgent} that simplifies the procedures to implement a backup agent by |
| 19 | employing backup helpers such as {@link android.app.backup.SharedPreferencesBackupHelper} and |
| 20 | {@link android.app.backup.FileBackupHelper}.</p> |
