#Scala on Android: Training

This repository is aimed at developers who want to know how to work in Android using the Scala language. We have created different commits where you can learn step by step. The commits are:

1. Preparing the environment: In this commit you can check how to prepare your project and SBT configuration. You can learn more about that in these posts: Preparing the environment and Setting SBT Configuration
2. DI: APIService and UserService: We are using for this example the Cake Pattern as way to provide compile time dependency injection.
3. Preparing UI: Here is were we add the activity, layouts, adapter and everything we need for our UI
4. Services & UI Integration: We connect our services to UI
5. Tests: Tests for our services

About Example

The app shows different users listed showing their name and age. We preload the list with several default users and we use the API at random.org to create random users from Internet and as way to demonstrate async http resource access
