The Weather App in Jetpack Compose using Kotlin | Part 1: Prerequisites | Android Knowledge

Summary

In this tutorial series, the creator guides viewers through building a weather app using Jetpack Compose. They start by setting up prerequisites like adding dependencies for Retrofit and MVVM, defining colors, and obtaining an API key from OpenWeatherMap. The UI is kept simple, focusing on logic over design. The app will fetch and display weather data for a user-specified city, including temperature, humidity, and a description, using the OpenWeatherMap API. The series is divided into three parts: prerequisites, Retrofit setup, and UI design with Jetpack Compose.
