I have a project for uni which consists in a remote controlled raspberry pi car. All the hardware is on point, I only need a way to control the car. I tried controlling it by running a local site on the raspberry using python and flask which has four buttons : Forward, Left, Right, Backward.
I have decided to develop an android app which would control the car by having the same four buttons. It should work like this: raspberry connects to the same wifi as phone (mobile hotspot in this case) and everytime i press a button in the android app, it would send the proper command to the raspberry, just like the web site version would have done;
I have no experience in programming android apps so that is why I am posting this here.
TL;DR
I need help in developing an android app to control an rc raspberry car (through wifi)
