android-things-button-examples

This repository will demonstrate the different ways in which you can access and deal with physical buttons on Android Things.

There are 4 different ways in which you can use/access a button in Android Things:

Simple Peripheral I/O

Consuming the Peripheral IO, we can get raw access to the GPIO pin which will receive the value if the button is pressed or not.

Button Input Driver

You can create your own custom Input driver combined with a GPIO pin, that will trigger normal key events. On this branch, the KEYCODE_SPACE is triggered when the button is pressed. This is a basic naive approach example of writing a custom user driver.

Button User Driver

This is based off the contrib-driver libraries given in the android-things repository. It triggers a KEYCODE_SPACE but the driver itself is not written here. It comes from the library.

Master - Button Library Callback - No KEYCODE events

On master branch, the android things contrib-driver is used, but we do not use the onKeyEvent method, we use the callback defined on the Button.
