Listing 1112 Example of Extending the Backup AgentHelper

public class MyFileBackupAgentHelper extends BackupAgentHelper { ^Override public void onCreate() {

FileBackupHelper filehelper = new FileBackupHelper(this,

DATA_FILE_NAME);

addHelper(FILE_HELPER_KEY, helper); SharedPreferencesBackupHelper xmlhelper

= new SharedPreferencesBackupHelper(this, PREFS); addHelper(PREFS_BACKUP_KEY, helper);

All backup agent helpers need an onCreate() method.The BackupAgent can have more than one backup helper. In the class extended with BackupAgentHelper, it does not need to override onBackup and onRestore because it is handled well by the BackupAgent.
