Dualshock 4 input for Android

Hi
I recently purchased a Samsung Gear VR and are making a project for it. I have managed to hook up my Dualshock 4 via Bluetooth to ky phobe so I can control the movement of the character however I want to use the buttons on the Dualshock to perform simple actions - like picking up objects but the buttons dont seem to work. I have used the gamepad inputs. I know all features dont work but is there a simple way to make the basic triggers register in the Gear VR

Thanks
Ben
