I want a sound to be played when the user presses the power button, Since I am customizing Android for Visually Challenged people this feature might let them know if the tablet has actually powered on or not.
This feature is by default switched off in my firmware. And also I think that since this sound comes just when the device is switched on, that is, before the Android Boots, the power on sound should be a function of underlying Linux kernel.
Any clue how to go about it and turn it on. Thanks in advance.
