How to read data(measurements) from Arduino Ethernet Web Server


I am new on android development. I have an Arduino connected to a temperature sensor that sends the measurements via ethernet on a webpage. Arduino acts as a webserver. I want to build an application that will display all the measurements that gathers from the webpage. More specifically I need to keep history of the measurements, and not just keep the last one. Any idea where to start?


Thanks! I mean I want to build an android application for my samsung mobile phone in order to gather the measurements and keep the history, obviously display the measurements + control button and things like this...

Do you know how to code in either Java or Kotlin? I believe that's what's used for building Android apps with Android Studio.
