Learning Objectives

This example is intended as a starting point for anyone planning develop actor-based Android applications using Scala and Akka. Its learning objectives are:

• Android application development using Scala
  • using the Simple Build Tool (sbt) for Scala in conjunction with pfn's well-maintained plugin
  • using IntelliJ IDEA
• Android application architecture for testability and maintainability
  • Dependency Inversion Principle (DIP)
  • Model-View-Adapter architectural pattern
  • Separation of Android activity into event-handling and lifecycle management
  • Separation of concerns among components using Akka actors
• Effective testing
  • Unit testing and Behavior-Driven Development (BDD) with ScalaTest
  • Mock objects with ScalaMock
  • Functional testing (out-of-container) using Robolectric
• End-to-end example of continuous integration (CI) for Scala/Android (see status badges at the top of this file)
