MyRed

A sample android app that shows how to use MVVM with Coroutine & Room database with the Koin dependencies injection, in Kotlin by “Clean Architecture”.

Gradle is convert to Kotlin, every build.gradle are build.gradle.kts

The Goal is to get all the Audios from the device’s Provider and show it up.

Implemented by

The structure of this project with 3 layers:

• ui
• domain
• data

Communication between layers

1. UI calls method from ViewModel.
2. ViewModel executes internal logic.
3. Internal logic receive/save/give data from/with Repo.
4. The Repo is tied with the data (Room database here).
5. Information flows back to the UI by LiveData.
