COVID-19 Tracking App (Robinhood Style) Ep 2: Retrieving Data from the API - Android Studio Kotlin

In this episode (2 of 8), we use The COVID Tracking Project API in order to retrieve the data that will power our application. We use the Retrofit library to make the API call and map it to a CovidData data class. Since there are no UI changes in this video, we use the debugger to validate our progress. Code written in this video: https://github.com/rpandey1234/Covid1... In this series, we build an open-source Android COVID-19 tracking app using core UI components from the Robinhood stock trading app. The app displays key metrics around the growth of coronavirus, including the number of positive cases, negative cases, and deaths per day.
