  1. Dagger 2

  2. MVI Architecture



What you'll learn:

    1. Advanced coroutine management using jobs
    2. Cancelling active jobs
    3. Coroutine scoping
  • Navigation Components:
    1. Bottom Navigation View with fragments
    2. Leveraging multiple navigation graphs (this is cutting edge content)
  • Dagger 2:
    1. custom scopes, fragment injection, activity injection, Viewmodel injection

    1. Cancelling pending network requests (Kotlin coroutines)
    2. Testing for network delays
  • Pagination:
    1. Paginating objects returned from server and database cache
  • Material Design:
