I am trying to develop an application on android to work as a screen for inputs data and these data will be processed to generate some interfaces after some amount of time. It is a sort of human-android interaction. During the processing I want the android to be connected to raspberry pi and instruct GPIOs to move a servos.
I would be grateful if i get any direction to walk through.
Now (since December 2016) You can do it with Android Things on Raspberry Pi side.
