Device Owner without using NFC in Android Lollipop

I want to make my app as Device Owner without using NFC or Root, On developer blog mentioned that to make device owner you must use NFC but according to my requirement i have to make it without using NFC because may some devices do not support NFC, i found it is possible as mentioned by alex_au under this comment. "Device Owner on Android 5.0 (and others) whitout rooted devices, device provisioning by NFC" on StackOverflow.

I have tried this but did not get success yet, please help me out if somebody has got success to accomplish it.

Any Help Would be highly appreciated.

Thanks
