Android Clean Architecture

👉 Clean Architecture:

👉 Domain & Data Layer:

👉 Presentation Layer:

👉 Architecture:

  • Following Clean Architecture.
  • MVVM Architecture.
  • Repository pattern.
  • Use Cases.
  • Applying SOLID principles, each class has a single job with separation of concerns by making classes independent
    of each other and communicating with interfaces.
  • Using Kotlin-KTS & buildSrc to handle project dependencies.

👉 Tech Stack & Libraries:

  • Navigation component – navigation graph for navigating and replacing screens/fragments
  • DataBinding – allows to more easily write code that interacts with views and replaces findViewById.
  • ViewModel – UI related data holder, lifecycle aware.
  • Flow & StateFlow – Build data objects that notify views when the underlying database changes.
  • Dagger-Hilt for dependency injection. Object creation and scoping is handled by Hilt.
  • Kotlin Coroutines – for managing background threads with simplified code and reducing needs for callbacks
  • Retrofit2 & OkHttp3 – to make REST requests to the web service integrated.
  • Coil – for image loading.
  • Material Bottom Navigation – to handle bottom tabs with support for multiple backStack.

👉 Project Structure:

  • Sample includes some basic features required in each project like :
    • Splash.
    • App Tutorial.
    • Login – (With Business Logic).
    • Sign Up – (Blank Screens).
    • Forgot Password -(Blanck Screens).
    • Home Screen – (Contains 3 Tabs with 3 NavGraphs).

👉 Extra Modules:

  • You will find extra modules also developed by me like :
    • AppTutorial – (To handle onBoarding tutorial screens).
    • ActionChooser – (A customized pop up with recyclerView of single selection).
    • PrettyPopUp (A customized pop up to display message to user with two actions (positive & negative buttons)).
    • ImagesSlider (An images slider supports auto scrolling for images from url and support GIF images).

👉 Code Style:

  • Following official kotlin code style

👉 Apply Git Hooks:

  • To apply git hooks in order to automate process of styling and checking your code, just follow this steps:
    • Copy pre-commit file depending on your OS from myGitHooks.
    • Paste it into .git/hooks in your project.
  • Now each time you commit your changes, ktlintFormat and ktlintCheck will automatically run

👉 Local Development:

  • Here are some useful Gradle commands for executing this example:
    • ./gradlew clean – Delets build directory.

👉 TO DO:

  • Apply ktlint for checking code style.
  • Use git hooks to automate code checking and styling before any new commit.
  • Use Flow in Domain layer.
  • Use StateFlow in Presentation layer.
  • Use UseCases.
  • Handle Different Build Variants.
  • Use Ktor as network client instead of Retrofit & OKHTTP.
  • Use Data Store instead of Shared Preferences.
  • Explore full MVI implementation.
  • Add some unit tests.
