Beers App – A Demo Android App Code

Description

The app displays a list of dummy beers from a JSON hosted on this github server.

It originally connected to an API to download a beer catalog based on Brewdog’s DIY Dog (hence the name of the project), but unfortunately the API shut down.

Data is always saved to the device (using data persistence with Room) and is consumed from there when it exists.
