How to enable dpad in android studio? I read that I need to change the hw.dPad parameter in hardware-qemu to yes - I changed it, but when I start the virtual machine, this parameter is reset to no and again dPad does not work. How to turn it on or which key is responsible for pressing the center key on the dPad, who knows? I tried pressing "5" on the add. clave, but there is a normal input of a number, and not pressing the center key on the emulator.
