Thanks eps. There isn't a Module for Activity_Keypress. I searched the code and the message that comes up isn't in the sample code ("App is pinned: Unpinning isn't allowed on this device."). I'm guessing the message is coming from the Administrator library. Should I be editing this library? or something else?
Which might help - someone has altered the Administrator library, so it is possible - I guess you'd have to go digging around in the code and see if you could generate a new jar
Thanks for the suggestions guys.
DonManfred, I found the reference to the Immersive Mode example and used the code there to hide the Nav bar. The back button is still available by swiping up but overall the interface is cleaner and it makes that toast message a bit harder to trigger. Thanks!
