Hi. Well...the class name of my backupagenthelper altered in the proguard.cfg(my config file name) with below setting. *-keep public class * extends android.app.backup.BackupAgent -keep public class * extends android.app.backup.BackupAgentHelper *And the command 'adb shell bmgr run' also works fine.
This is randomly occur in idle time when user not using the app which is I don't understand... Here is the my situation again clearly fyi, -My 'BackupAgent*Helper*' exist in the path -It defined in Manifest.xml. -Backup request queue processed well by 'adb shell bmgr run'. -Proguard also avoid obfuscation for this class by config. -BackupAgentHelper added from someday wihile distributing. Mean that previously my 'BackupAgent*Helper*' doesn't exist. It is newly supported from someday. -This error occur randomly from everywhere in OS since at least froyo. -No right answer exist so far. -This occur when run UNSIGNED binary either. Does above situation seem okay..? One thing weired is why OS looking path '/data/app/' ?? Do you know that?
