A sample modular Android app

This sample app has been developed with Kotlin following an MVVM architecture pattern with a modular approach.

Working

Branches

master

Koin: Dependency injection
Reactive streams: Networking & Async.
LiveData and ViewModel: Isolate business logic and maintain state.

coroutines

Dagger 2:Dependency injection
Coroutines: Networking & Async.
LiveData and ViewModel: Isolate business logic and maintain state.

Decisions

Koin: This is my first experiment with Koin, and it turned out to be straight-forward to implement. The performance is also great. Although, feature module support is something they are still working on.
Modular: The app is developed with a modular approach to support instant apps & dynamic delivery for the users. Modularity also allows us to have faster gradle build speeds, clear ownerships amongst the team & cleaner git flows. More info about modular apps can be found here.

Structure

app module is where the application initializes & characters dynamic module is where our sample screens reside. CharacterActivity holds the CharacterSearchFragment & CharacterDetailsFragment. The packages are "by-feature" for easier access.

Running

You will need a device / emulator with Android Oreo (API 27) and up. Configuration

Testing

Test cases for the CharacterSearchVM & CharacterDetailsVM have been implemented.

Write-ups

Rx vs Coroutines: Complex network chains on Android
