java - Why doesn't Backup Manager finish my backup? -


    public class mybackupagent extends backupagenthelper {         static final string db_file_name = "name";         static final string db_backup_key = "key";          @override         public void oncreate() {             filebackuphelper dbs = new filebackuphelper(this, getfilespath());             addhelper(db_backup_key, dbs);         }          private string getfilespath() {             file path = getdatabasepath(db_file_name);             return path.getabsolutepath();         } } 

the reported output is:

04-27 21:54:13.681: v/backupmanagerservice(1087): addpackageparticipantslocked: #1 04-27 21:54:13.681: i/backupmanagerservice(1087): scheduling backup new app my.package 04-27 21:54:13.681: d/backupmanagerservice(1087): staging backup of my.package 04-27 21:55:11.621: d/backupmanagerservice(1087): couldn't find params token 0 

what problem?
