I would like to build a simple Android OS app using Android Studio (absolute beginner other than Pascal) for my school that lists its upcoming events (e.g. Graduation along with a description and date and time) that can be refreshed by the user. I would like to know how do I get around creating this app and more importantly, how to host a service on my old PC that I can easily input new events and have the app 'grab' these new events off of it. I will greatly appreciate any help/resources you guys can share.
