Hello! I am absolutely new to android and web development. I would like to make an app which I can use to login to my account on a website (https://mijn.park-line.nl/bzp/DenHaag.asp) and to be able to start and stop the parking time. It should also show the time passed and notify every 30 minutes about it. I am not looking for code (but of course, it would be nice to have some examples) at this moment but for some tutorial or a list of functions which I need to program to make such an app. If there is an existing application which I can modify for my needs, I can also try it. I tried to search but the most of the content assumed for people with some knowledge of http post (I even do not know what it is) and others. Please give me some hints or links where I can find such information. Thank you.
