Starter code for Android Basics in Kotlin.


Using this stater code you will create MarsPhotos is a demo app that shows actual images of Mar’s surface. These images are real-life photos from Mars captured by NASA’s Mars rovers. The data is stored on a Web server as a REST web service. The solution app will demonstrate the use of Retrofit to make REST requests to the web service, Moshi to handle the deserialization of the returned JSON to Kotlin data objects, and Coil to load images by URL.

The app also leverages ViewModel, LiveData, and Data Binding with binding adapters.
