The data input is my laptops touchpad, because sneaky elves have hidden my joystick/gamepad  !

At first I thought the keyboard & touchpad did not work, but it turns out they will emit data if the java app has "focus" - to have focus I started the old GUIService ...  Can't seem to get rid of the thing :P

Hi Peppexhio,

Any service exposes all its methods through the web api.  You can use http requests, or websockets.

This page describes it 

http://myrobotlab.org/content/myrobotlab-api 

You can also send parameters to the method python's   methodExec

This method takes an object array, so you it must be a POST and not a simple GET.

If Android appinventor can make a post - it should be possible.
The example below is done with Postman and will invoke a 2 parameter method called 'parm2' if defined in python.

e.g.

def parm2(p1, p2):
   print('p1 is ', p1)
   print('p2 is ', p2)
