In the kiosk app example, it was mentioned to add the attirbute android:testonly = "true" into
the {device_admin.xml} file which was created by the manifest editor file.
May I know the correct way of doing this.
If I insert that attribute in position 1 - I think this will not create the attribute in the [device_admin.xml}.
Whereas if I put it in position 2 - I will a have a compilation error as it is not a correct syntax.
Kindly advise.
Thanks

Sounds strange. Why is it needed?

I had tested with the application attribute testonly added, I will not be able to uninstall the file after I used the
cmd line "adb shell dpm set-active-admin b4a.example/kioskapp.AdminReceiver2"
to make the app as an active admin app.
Why this happened as it was mentioned that if the app is a testonly app, it can be removed at any time.

My reply: I'm not familiar with this attribute and didn't use it in my tutorial.

You could also try uninstalling it programmatically: https://stackoverflow.com/a/50257835

Actually I've got this working. Removing the app can be done by first running adb remove-active-admin, then uninstalling the app as usual. I'll write a tutorial and I'll post it on the forum in the next day or two.
