So, I am following the instructions here:

https://www.b4x.com/android/forum/threads/device-owner-tasklock-kiosk-apps-2017.81765/page-2

However the ADB setip isnt working properly. on my Samsung Tab E, I keep getting this:

Z:\android-sdk\platform-tools>adb shell dpm set-device-owner b4a.example/anywher

Z:\android-sdk\platform-tools>

looks like a Knox block.

any ideas?

Figured it out. I had to un-enroll the device from Knox. We had it on our corporate Knox account in case it gets stolen, it can be tracked/locked out. So if your running knox, it becomes the defacto admin app.
