Coroutines Flows - Modularised 🚀
Table of Contents
The purpose of this project is to consolidate some of the learned insights throughout the years about the
Clean Architecture principles and reflect those lesson on Android, taking advantage of the Kotlin programming language features too.
This project summarises some of the general use cases and needs that could be demanded on a production project using:
Kotlin Flows and
LiveData (I've kept a branch using
On Going Work
🔛 Paging 2 library integration
🔛 UI Update
🔜 Jetpack Compose
app - The application module with access to all the application
data - Android module that can only access domain module
data-api - Android module that can only access data module
domain - Kotlin module that cannot access any other module
presentation - Android module that can only access domain module
navigation - Android jetpack navigation abstraction (it contains the navigation config file) cannot access any other module
And two extra modules:
core - Base classes module (factories, events, etc.) that cannot access any other module
core-android-test - Tests classes module (rules, date builders,etc.) that cannot access any other module
There are some highlights:
- Every layer in the architecture has been tested with its mapper|transformer|provider.
- Mockito has been used for mocking|stubbing.
Given|When|Then steps have been followed, in order to give a more structured overview.
I opted for a dynamic test configuration, so it's possible to inject different configurations as peer need. Find more info in my post right here 👉 Medium Post
- In order to mock the responses and use them for instrumentation testing, I've used MockWebServer.
- In order to give a concise and clean face of the Espresso tests, I've applied Robot Pattern.
Coroutines Library support for Kotlin coroutines.
Flows for asynchronous data streams.
LiveData for reactive style programming (from VM to UI).
Navigation for in-app navigation.
Dagger2 for dependency injection.
Retrofit for REST api communication.
Timber for logging.
Espresso for UI tests.
Mockito-Kotlin for mocking in tests.
MockWebServer for Instrumentation tests.
AndroidX Test Library for providing JUnit4 and functions as
launchActivity in UI tests
Picasso Image downloading and caching library
JodaTime Date library that lets manage more extensively and easily dates
BottomSheet Library that contains a bottom sheet view with animations (expand/collapse)
SolidAdapter Library that provides a SolidAdapter implementation, instead of RecyclerView.Adapter
