Basic Code demo to cover:

• MVVM
• Clean Architecture
• Coroutines
• Repository pattern
• Local data source ( Room )
• Remote data source ( Retrofit )
• DI
  • Dagger2 ( master branch )
  • Hilt ( using_hilt branch )
• Android Test
  • DAO test
  • More to add
• Local Test
  • Livedata test
  • ViewModel test
  • Test doubles ( FakeRepository )

Structure:

• Presentation
  • View
  • ViewModel
• Domain
  • Usecase
  • Repository Interface
• Data
  • Repository Implementation
  • Data Sources

Quick Intro:

• LiveData
  • Android LiveData is lifecycle aware, observable data holder class
  • As its name suggest, we use to get live data
  • In another words, to get real time updates form the data source
  • Define a LiveData instance var count = MutableLiveData()
  • Update a LiveData instance count.value = 0
  • Obaseve a LiveData instance viewModel.count.observe(this, observer{ // Update UI })
