How do I set Android app as device owner?

I'm developing Kiosk Mode App for my organization.

The only thing I want is to set my App as device-owner-mode to launch the app in Kiosk Mode. I am debugging this by using adb shell to set this app as device owner. The problem is how I set this as device owner on the other device without using adb???

I found some ways by scanning QR code Provisioning.. but this method is really confusing.. Should I develop EMM Console kind of thing to do this..?

As I said the only thind I want is just set the app as device owner. No need for managing that device or create multi profile.

How can I do this?? Please help. Thank you

To set your app as device owner via QR code provisioning you need to:

• host your APK on a public URL
• generate a QR code containing your APK URL and checksum, along with your package name and admin receiver name (cf example)
• factory-reset your device
• tap 6 times on the initial setup screen
• scan your QR code
