Project tutorial by Joppe Smeets and Pieter Luyten
For this you first have to install Android Studio, you can download it here: https://developer.android.com/studio/ . I will update the project by the end of June and provide more detailed instructions. In the meantime, you can already search for ‘Parsing JSON, Android Studio, Volley Library’. These instructions may help you: https://www.thorntech.com/2016/03/parsing-json-android-using-volley-library/
You can also use a NodeMCU development board for ESP8266 ($2-8). I can make a tutorial about this by the end of June or you can search for 'ESP8266, HTTP Post request, Arduino' on the internet.
