A sample android app that shows how to use ViewModels and Room together with RxJava & Dagger2, in Kotlin by Clean Architecture.

Implemented by Clean Architecture

The following diagram shows the structure of this project with 3 layers:

  • Presentation
  • Domain
  • Data


Communication between layers

  1. UI calls method from ViewModel.
  2. ViewModel executes Use case.
  3. Use case combines data from Album and Photo Repositories.
  4. Each Repository returns data from a Data Source (Cached or Remote).
  5. Information flows back to the UI where we display the list of posts.

Scenario

Used https://jsonplaceholder.typicode.com/ as a public api to generate fake data for testing

At a glance:

  • Created a list of Album
  • In the Item of each Album, showed Album name.
  • When user taps on Album, new page will be shown which includes list of photos.
  • when user taps on photo, show image bigger through transition.
  • Were Written tests to completely cover Exceptions/Expectations
  • And:
    • Supported orientation change
    • Supported offline mode
