I have connected several external devices through GPIO , SPI , I2C and UART peripheral ports to my RPI 3. I am using Android OS on my RPI too.
My goal is developing a GUI android launcher run on my RPI and communicate with the external devices and user can control these devices easily. I do not want to use Android things OS because it is so limited.
How can I use WiringPi library in my android application(launcher)?
