What this log is mean?

My application couldn't get the device admin because unknown errors occur. 
The error log next below is log when my application to get the device admin.

<Log>
KnoxCustomManagerService(950)getSealedState() failed-persistence problem com.android.server.enterprise.storage.SettingNotFoundException: Admin data is null

Please tell me what the problem is and what the way for solving it.
(The application got the ELM license key by samsung. And it was no problem on the most samsung android devices. But 1~2% devices has problems that couldn't to get the device admin.)

Thanks.

Hi Chulok,

Please verify if the issue persist when you are launching sample application from SEAP portal:
https://seap.samsung.com/sdk/knox-standard-android/sample-apps

Probably this issue regarding your implementation of administrator activation class.
