Objective of this repository is to reduce the classes from original sample and make it easy to understand

also add the actual retrofit API call and some more

Android Architecture Blueprints - AAC + Dagger2 + Dagger-Android

Summary

This sample is written in Kotlin and based on the master branch which uses the following Architecture Components:

• ViewModel
• LiveData
• Data Binding
• Navigation
• Room

It uses Dagger 2 and Dagger-Android for dependency injection. The Dagger setup is deliberately simple and unopinionated.

Differences with master

• The ServiceLocator class is removed. Object creation and scoping is handled by Dagger.
• Flavors mock and prod are no longer needed for testing so they're removed.

Key files

The di directory contains all DI-related classes. This is done to improve browsing the files but feature modules are usually placed alongside their packages (i.e. TaskDetailModule in the detail package).

ApplicationComponent and its testing counterpart TestApplicationComponent define different modules for production and UI testing.

Testing

UI tests don't rely on using the mock flavor to run quickly and hermetically. Instead, they replace Dagger components with their test versions.

This is done by creating a CustomTestRunner which starts the TestTodoApplication instead of the TodoApplication. DaggerTestApplicationRule creates the TestApplicationComponent and injects the Application.
