Title: How to disable internal keypad while external keypad is connected to rk3399
Hello,
My problem is, I want to disable internal keypad only when the external keypad is attached to rk3399.
Can we do this? And Can we do this from an android application or this can be done through firmware modification only? If we have to go with firmware modification only then what they should be?

I have tried this code but when I attach external keyboard it doesn't detect it and always go to this condition "config.hardKeyboardHidden = Configuration.HARDKEYBOARDHIDDEN_YES";

I also want to hide softKeyboard when external one is connected. Is there any way to hide it permanently until the External keyboard is detached?

I have tried the code you have suggested.
In Firefly when I attach an external keyboard and in Settings->Languege/Input->Physical Keyboard->show virtual keyboard I keep it disabled, it is still showing virtual keyboard.
