Learn how to create an Android app with Kotlin that uses core UI components from the Robinhood stock trading app. Instead of tracking stocks, this app will track COVID-19 cases. The app displays key metrics around the growth of coronavirus, including the number of positive cases, negative cases, and deaths per day.
We use data from The COVID Tracking Project (https://covidtracking.com/api).
If you’re encountering an issue with views not being resolved in the Kotlin file, you should get a reference to the view with findViewById at the top of MainActivity.
