The best way to make the modules stick is to build something. These five projects take you from a first Kotlin app through Jetpack Compose UI, a Room and MVVM notes app, a Retrofit weather app, and finally a release build published to Google Play.
Each one is a code-along video, so you can pause, type it out yourself and adapt it to your own ideas. Pick the project that matches the module you've just finished and come back for the rest.
