Everything work well when I follow the guide.However when I try to build my own COSU application, CMD give me this exception after I write adb command:

adb shell dpm set-device-owner com.example.myapp/.DeviceAdminReceiver
java.lang.SecurityException: Neither user 2000 nor current process has com.sec.enterprise.permission.MDM_PROXY_ADMIN_INTERNAL.

Actually, there is no issue. I was writing the package name incorrectly! :) but the error message seems useless

I am facing the same issue, what do you mean incorrect package name.. I provided the package correctly but still get the same error
