Audio player sample app

This is a sample project where I experimented with ExoPlayer

Libraries/architecture used

ExoPlayer 2
Hilt
Android Architecture Components
JUnit5

What's implemented?

Loading multiple media sources
Music playback with a system notification synchronised with playback actions
Error handling
Audio Service is in a separate Gradle module - the main module does not know anything about ExoPlayer nor the Service itself
sample JUnit5 unit & instrumentation tests

How does it look like?

TODOs

add a :core module and a feature module
Loading music list from an external source e.g. a Web Service via Kotlin coroutines
