API for controlling GPIO pins from Android apps

[tllim]

This is actually why I joined the forum. I want to be able to have Android accept input from a set of GPIO ports and automatically initiate a proper shutdown/startup sequence. I want to build a CarPC with this because it's a lot better than the RPi2 I'm using right now.

I'm using the Mausberry 3A switch (link below) to provide power to everything only when the car is turned on. It send signals to the GPIO pins to initiate the proper shutdown and startup. I'm hoping to be able to incorporate this in Android and the Pine64.

Well, doing a little more research I found that we have an EXP Connector now that's not on the schematic I have printed out. I found the updated pinout on the wiki (https://drive.google.com/file/d/0B0cEs0l...IzTlE/view) that shows hardware pins that allow for a power and reset switch that is integrated into the Android image. Perfect. Looks like this will work flawlessly right out of the box. This is turning out to be one of the best boards on the market as you don't need to waist a GPIO pin for a power switch.

EXP circuit is on the schematic.
