Architecture

• 

• 

• 

• The entity/domain:

  • Only contains business models

• The dataprovider:

  • Provide data from repository:
    • Can get from remote source by using retrofit and map raw data model to business model
    • Or, get cached from local source by using room database from framework

• The usecases:

  • Provide the interaction with dataprovider for app UI

• The framework:

  • Implement caching by using Android framework: room database

• Main app:

  • Apply MVVM architecture
  • Apply Dependency Injection by using Dagger

Code folder structure

• 
  • Contains 4 modules: entirty, usecases, dataprovider, and main app
  • app contains:
    • base: define some base classes that will be extented in the application
    • di: define dependency injection with application scope
    • ext: define extensions will be used in the application
    • features: separate application into many features will make it be easier on scaling up
    • framework: implementation of Android framework

Framework, library and run

• Libraries/frameworks using in the application:
  • Kotlin
  • Coroutines
  • Room
  • Retrofit
  • Dagger
  • Rootbeer
  • Mockito
• Required configurations:
  • AndroidSDK
  • Gradle 6.5
• Launch:
  • Windows
